Question 1
Match each of the following types of islands with its description.
volcanic islands
coral islands
continental islands
2 pts

Answers

Answer 1

Volcanic islands: Volcanic islands are formed as a result of volcanic activity and they emerge from the sea floor as a result of volcanic eruptions. Coral islands: Coral islands are created by the buildup of coral reefs, and the islands are essentially made up of coral structures that have been lifted up by the force of the ocean’s waves. Continental islands: Continental islands are those that are located on a continental shelf and were once a part of the mainland but were separated from it as a result of rising sea levels.

Volcanic islands are generated through volcanic activity, emerging from the ocean floor due to volcanic eruptions. These islands form as molten lava, ash, and other volcanic materials are expelled, gradually accumulating and building up the landmass above sea level. Coral islands, on the other hand, originate from the accumulation of coral reefs. Over time, coral structures grow and develop in shallow, tropical waters. As the reefs continue to expand, they contribute to the formation of an island. Continental islands are distinguished by their location on a continental shelf. These islands were once connected to the mainland but became separated as rising sea levels submerged the land bridge that linked them.

In summary, volcanic islands arise from volcanic activity, coral islands form from accumulated coral reefs lifted by ocean waves, and continental islands were once connected to the mainland but became isolated due to rising sea levels.

Ecological succession is defined as the gradual process of change and replacement of different species in an ecosystem over time. Several models of ecological succession have been proposed and these include the tolerance model, nutrient depletion model, inhibition model, and facilitation model. The Facilitation Model is one of the models proposed in ecological succession. In the Facilitation Model, early species modify the environment in such a way that they enable the survival of intermediate species. The intermediate species in turn modify the environment, making it less suitable for early species and more suitable for late-stage species.

Late-stage Climax species do not change the environment in ways that favor other species. The model of ecological succession that has the above-mentioned characteristics is the Facilitation Model. It is worth noting that the Facilitation Model is a type of ecological succession where early colonizers pave the way for other species to succeed them. These early species modify the environment in a way that enables the survival of the intermediate species.

If a barometer reads 755 mmHg at the ground level before rising up a mountain (or a building) with a hight equal to the last 4 digits of your ID number. What will be the reading at the top of the mountain in mmHg? Take the densities of mercury and air to be 13600 kg/m³ and 1.18 kg/m³ respectively.

Answers

The barometric pressure at the top of the mountain (or building) is approximately 647.81 mmHg, considering a hypothetical height of 1234 meters and using the given values for air density and the conversion factor.

To calculate the barometric pressure at the top of the mountain (or building), we need to consider the change in pressure with height using the concept of atmospheric pressure gradient.

The change in pressure with height is given by the formula:

ΔP = ρ * g * Δh,

where ΔP is the change in pressure, ρ is the density of air, g is the acceleration due to gravity, and Δh is the change in height.

The density of air (ρ) is 1.18 kg/m³ and the density of mercury is 13600 kg/m³, we can convert the barometric pressure at ground level from mmHg to Pa using the conversion factor 1 mmHg = 133.322 Pa.

Let's assume the height of the mountain (or building) is 1234 meters (using a hypothetical value). Now we can calculate the change in pressure:

ΔP = ρ * g * Δh

  = 1.18 kg/m³ * 9.8 m/s² * 1234 m

  = 14,287.24 Pa

To convert the change in pressure from Pa to mmHg, we divide by 133.322:

ΔP (mmHg) = 14,287.24 Pa / 133.322 mmHg

            ≈ 107.19 mmHg

To find the barometric pressure at the top of the mountain, we subtract the change in pressure from the initial reading:

Barometric pressure at the top = 755 mmHg - 107.19 mmHg

                                       ≈ 647.81 mmHg

Therefore, the barometric pressure at the top of the mountain (or building) would be approximately 647.81 mmHg.

which is one way that analyzing ice benefits scientists who study ancient climates?scientists can analyze frozen volcanic dust to help predict eruptions. scientists can study the layers of ice

Answers

One way that analyzing ice benefits scientists who study ancient climates is by studying the layers of ice.

Analyzing the layers of ice in glaciers and ice sheets provides valuable information about past climates and environmental conditions. As snow accumulates over time and compacts into ice, it forms distinct layers that represent different periods of time. By drilling ice cores and extracting samples from these layers, scientists can obtain a chronological record of climate variations and atmospheric composition stretching back hundreds of thousands of years.

The composition of the ice layers contains a wealth of information. For example, the ratio of stable isotopes of oxygen and hydrogen in the ice can provide insights into past temperatures and precipitation patterns. Air bubbles trapped within the ice contain samples of ancient atmospheres, allowing scientists to reconstruct past levels of greenhouse gases and trace the impact of human activities on climate change.

By analyzing ice cores, scientists have been able to reconstruct past climate events, such as ice ages and interglacial periods, and understand the factors that influence long-term climate variations. This knowledge helps improve climate models and predictions for the future, providing valuable insights into the potential impacts of ongoing climate change. In addition to studying the layers of ice, scientists can also analyze frozen volcanic dust in ice cores to gain insights into past volcanic activity and its impact on climate, which can aid in predicting future eruptions.

Using these observations, answer the following questions (7 marks) 1) Identify the diameters of the three particle classes. Show your work (6 marks) 2) Using the diameters you calculated, identify the name of this soil. (1 mark)

Answers

The settling behavior of soil particles can be analyzed using observations and Stoke's Law to calculate particle diameters, which can then be used to classify the soil type according to standard soil classification systems.

How can the settling behavior of soil particles in a water column be used to determine particle sizes and classify the soil type?

The given information describes the settling behavior of soil particles in a water column, which can be used to determine the particle sizes and classify the soil type. Here's a breakdown of the answers:

1) To identify the diameters of the three particle classes, we can use Stoke's Law, which relates the settling velocity of a particle to its diameter. The settling velocity can be calculated using the observed settling times.

Let's denote:

D1 = diameter of the first particle class

D2 = diameter of the second particle class

D3 = diameter of the third particle class

Using the given observations:

a) After 1 minute, 70% of the soil sample fell. This indicates the settling velocity of particles of diameter D1, so we can use Stoke's Law to solve for D1.

b) After 8.5 minutes, 20% of the soil sample fell. This corresponds to particles of diameter D2.

c) After 5500 minutes, the remaining 10% of the soil sample fell. This corresponds to particles of diameter D3.

By solving the appropriate equations using Stoke's Law, the diameters of the three particle classes can be determined.

2) Based on the calculated diameters, the soil can be classified using standard soil classification systems, such as the Unified Soil Classification System (USCS) or the AASHTO soil classification system.

Answers

If decomposition in a forest could be magically turned off, then the answer to this question is that "not much would change except deer and other herbivores would have more plants to eat".

The breakdown of organic matter into its inorganic components is known as decomposition. It is an essential process that recycles nutrients and breaks down waste in ecosystems, allowing for the development of new life. It converts the remains of dead plants and animals into nutrients that can be reused by other organisms in the ecosystem. If decomposition were to stop, a host of problems would arise.

The organic matter will begin to accumulate on the ground, and nutrients will be tied up in the dead and decomposing material, making them inaccessible to living plants and trees. This will result in a decrease in the overall productivity of the ecosystem. Additionally, the accumulated organic matter may serve as fuel for fires, which could result in more catastrophic fires if it continues to accumulate over time.Thus, the answer to the question is option a.

The following statements are true about geostationary weather satellites:

(E) They orbit the equator at a rate equal to that of Earth’s rotation on its axis.(F) They continuously monitor the weather over a particular region of the earth.

Therefore, option E and option F are correct.

Explanation:

Geostationary weather satellites are used to study and monitor weather patterns over a particular region of the Earth. They are placed in geostationary orbit around the earth's equator, which means they orbit the earth at a rate equal to that of the earth's rotation on its axis.

The benefit of the geostationary orbit is that the satellite can stay above a particular region of the earth continuously, providing up-to-date information about the weather patterns over that area. As such, they continuously monitor the weather over a particular region of the earth. This allows meteorologists to keep an eye on developing weather patterns, providing early warning of impending storms and other weather-related events.

However, they don't always provide more detailed images than polar-orbiting satellites. Polar-orbiting satellites have sensors and instruments that can collect more detailed information about the Earth's surface than geostationary satellites. They can also provide more detailed images of the earth's polar regions, which geostationary satellites can't do. And they have ceilometers onboard to detect clouds as well.

The stages in a normal star's life cycle, regardless of mass, are given below: Giant molecular cloud (GMC) Protostar Pre-main-sequence star/T Tauri star Main-sequence star Giant star (red or otherwise)Asymptotic Giant Branch star/Double/multiple shell-burning giant star (red or otherwise) Planetary nebula or supernova (see next question for more details) Supergiant star (red or otherwise)Horizontal Branch (HB) star/"He main-sequence" star/possibly a variable star Stars have a life cycle that starts with their birth and ends with their death. The life cycle of a star, however, is influenced by its mass.

As a result, high-mass stars evolve much more quickly than low-mass stars. The stage during which all stars fuse hydrogen into helium in their core is the main-sequence stage. During this stage, the force of gravity is in equilibrium with the radiation pressure generated by nuclear fusion in the star's core. The majority of a star's life is spent in this stage, during which it converts hydrogen to helium by nuclear fusion. This is the phase in which our Sun currently is.

As a result, the correct order is Protostar → Pre-main-sequence star/T Tauri star → Main-sequence star (during which all stars fuse hydrogen into helium in their core) → Giant star (red or otherwise) → Horizontal Branch (HB) star/"He main-sequence" star/possibly a variable star → Asymptotic Giant Branch star/Double/multiple shell-burning giant star (red or otherwise) → Planetary nebula or supernova (see next question for more details) → White dwarf or neutron star or black hole → End.

2. Discuss the THREE (3) parameters affecting the ultimate oil recovery of gravity drainage drive reservoir. • Permeability in the direction of dip Dip of the reservoir Reservoir producing rates Oil viscosity Relative permeability characteristics . .

Answers

The ultimate oil recovery of a gravity drainage drive reservoir is affected by permeability in the direction of dip, reservoir producing rates, and oil viscosity. Optimizing these parameters is crucial for maximizing oil recovery.

Gravity drainage is a reservoir recovery mechanism where oil is produced due to the natural downward movement of the oil towards a production well. The permeability in the direction of dip plays a crucial role in this process. Higher permeability allows for easier movement of oil through the reservoir, increasing the ultimate recovery. Conversely, lower permeability restricts the flow, reducing the recovery potential.

The dip of the reservoir refers to the angle at which the layers of rock and oil are inclined. It affects the efficiency of gravity drainage as the steeper the dip, the more effective the drainage. In such cases, gravity acts more strongly, aiding the movement of oil towards the production well. On the other hand, a gentle dip reduces the gravitational forces and makes the drainage less efficient.

Relative permeability characteristics describe the relationship between the effective permeability of oil and water as a function of saturation. It determines how easily the fluids flow through the rock formation. The relative permeability curves for oil and water provide insights into the displacement efficiency and the recovery potential. Optimal relative permeability characteristics favor a higher recovery factor.

In summary, the permeability in the direction of dip, the dip of the reservoir, and the relative permeability characteristics are key parameters influencing the ultimate oil recovery of gravity drainage drive reservoirs. Understanding and managing these factors are crucial in maximizing the recovery factor of such reservoirs.

The given statement, Experts estimate that most oil reaching the ocean comes from oil tanker accidents and pipeline breaks is true.

Oil spills from oil tankers and pipelines are considered to be the largest source of oil entering the ocean environment. Every year, millions of gallons of oil are spilled into the ocean due to accidents from these sources. Tanker accidents are the most common because large vessels often operate in hostile conditions and accidents on the high seas can be difficult to detect.

Many of the spills occur due to human error, such as crew failing to properly secure cargo during loading and unloading, or due to vessel structural issues. Pipeline breaks occur due to corrosion, natural disasters, maintenance issues and acts of sabotage. With pipeline spills, the sheer volume of oil is higher as the line can be pressurized, leading to much larger and more catastrophic spills.

How are convergent and divergent plate boundaries related to constructive and destructive plate margins?

Answers

Convergent and divergent plate boundaries are related to constructive and destructive plate margins in the following ways:

Convergent Plate Boundaries: These types of plate boundaries are where two tectonic plates come together, causing one to move under the other. This process is also known as subduction. It is related to destructive plate margins as it leads to the destruction of the subducted plate. At the same time, it also causes the formation of volcanic mountains, thus making it a constructive margin.

Divergent Plate Boundaries: These types of plate boundaries are where two tectonic plates are moving away from each other, and new oceanic crust is being formed from the magma that rises to the surface. This process is related to constructive plate margins as it leads to the formation of new crust. The Red Sea is an example of a divergent plate boundary that is still active.Constructive and destructive plate margins:Convergent and divergent plate boundaries are the two types of plate margins.

These plate margins can be further categorized as either constructive or destructive.

Constructive plate margins: These types of plate margins are where two plates are moving away from each other. The gap between the two plates is filled with magma that rises to the surface, leading to the formation of new crust. An example of a constructive plate margin is the Mid-Atlantic Ridge.

Destructive plate margins: These types of plate margins are where two plates are moving towards each other. One plate is subducted under the other, leading to the formation of a subduction zone. As the subducted plate is pushed deeper into the mantle, it melts, leading to the formation of magma. This magma then rises to the surface, leading to the formation of volcanoes.

Ocean salinity refers to the concentration of dissolved salts in seawater. While various factors can influence salinity, the overall balance between inputs and outputs of dissolved solids determines whether salinity increases, decreases, or reaches an equilibrium.

The statement that correctly reflects this is that ocean salinity has reached an equilibrium, as the addition of dissolved solids equals the removal of dissolved solids by geological, biological, and hydrological processes.

Salinity is regulated by a dynamic interplay of different processes. The addition of dissolved solids occurs through volcanic eruptions, which release minerals into the oceans.

On the other hand, the removal of dissolved solids happens through various mechanisms, including sedimentation, precipitation of minerals, and biological uptake by marine organisms.

Additionally, the input of freshwater from rivers and the output through evaporation also impact salinity. While global warming and the melting of glaciers can influence freshwater input into the oceans, it is not the primary driver of salinity changes.

The long-term balance of inputs and outputs, including both natural and human-induced factors, determines the equilibrium state of ocean salinity.

The development of a glacial period requires:
cool summers so that snow doesn't melt and ice sheets can
build.
cold autumns
extra cold winters so there is more snow.
cold springs

Answers

The development of a glacial period primarily requires cool summers, where temperatures remain low enough to prevent the melting of snow and allow for the accumulation of ice sheets.

These cool summers play a crucial role in building and sustaining glaciers. Additionally, cold autumns and winters contribute to the formation and growth of glacial ice by providing prolonged periods of cold temperatures and facilitating the accumulation of snow. The extra cold winters are particularly important as they ensure the preservation of snowfall and prevent it from melting. While cold springs are not directly essential for the development of a glacial period, they can contribute to the overall persistence of the icy conditions. Together, these factors create the necessary climate conditions for the formation and expansion of glacial periods.

In conclusion, the development of a glacial period is primarily dependent on cool summers, which prevent snow melt and enable the formation of ice sheets.

Earth’s natural carbon cycle influences the balance of greenhouse gases in the atmosphere but is being impacted by human activity. Evidence of this includes:
A. Ocean acidification and increased volcanic activity Increased tsunamis and ocean acidification
B. Ocean acidification, and increased global average temperatures
C. Decreased volcanic activity and increased tsunamis
D. Increased acid rain and increased tsunamis

Answers

Option B which is "Ocean acidification, and increased global average temperatures".

Earth’s natural carbon cycle regulates the equilibrium of greenhouse gases in the atmosphere, which helps maintain a moderate global temperature. However, human activities are increasing the concentration of greenhouse gases in the atmosphere, leading to a warming trend and other changes in the environment.

Among the human activities that influence Earth's carbon cycle are the burning of fossil fuels, deforestation, and other land-use changes. These activities are causing an imbalance in the carbon cycle, leading to a buildup of carbon dioxide and other greenhouse gases in the atmosphere, trapping heat and contributing to global warming.

Among the evidence of the impact of human activity on the carbon cycle are ocean acidification and increased global average temperatures, among others. Ocean acidification is caused by the increase in carbon dioxide in the atmosphere, which reacts with seawater to form carbonic acid, resulting in an increase in ocean acidity. Increased global average temperatures, on the other hand, are the result of the buildup of greenhouse gases, particularly carbon dioxide, in the atmosphere, which traps heat and warms the planet.

The other options mentioned, such as increased volcanic activity, increased tsunamis, and increased acid rain, are not directly related to the impact of human activity on the carbon cycle. Therefore, the main answer is option B, which is "Ocean acidification, and increased global average temperatures".

a) Define permeability. What three features influence this property in a geologic body?

Answers

Permeability can be defined as the ability of a geologic body to transmit fluids or air through it. It is the measure of the capacity of the rock or soil to transmit a fluid.

This ability is determined by the pore space and the degree of connectivity between pores. A material with high permeability permits fluids to pass through it more quickly than a material with low permeability.Furthermore, three factors that influence the property of permeability in a geologic body include:Porosity of the material: It is the amount of space between solid particles in a soil or rock mass. Materials with higher porosity can contain more fluid and hence have higher permeability size and shape of the pores: The size and shape of the pores is another factor that influences permeability. Larger pores have higher permeability compared to smaller pores.

The shape of pores also affects the rate of flow of fluids through a material as well as the distribution of the fluids.Connectivity of the pores: It is the degree of connectedness between pores in a soil or rock mass. In geologic bodies, a higher degree of pore connectivity translates into higher permeability. Highly connected pores facilitate the flow of fluids in a geologic mass, resulting in higher permeability.

Explain the conditions that make the climate on Antarctica
different to the climate in Papa New Guinea.

Answers

The conditions that make the climate on Antarctica different to the climate in Papa New Guinea are the latitude, the altitude, and the ocean currents.

Antarctica and Papua New Guinea are two different parts of the world with distinct climates. Antarctica has a cold, dry climate, whereas Papua New Guinea has a hot, wet climate. There are several reasons for this difference in climate conditions.

Antarctica is located at the southernmost part of the globe, near the South Pole. In contrast, Papua New Guinea is situated near the equator. The Earth's tilt and rotation result in differences in the amount of solar radiation that each place receives.

The topography of the two places is another factor. Antarctica has an elevation that is mainly covered with ice, which creates its cold, dry climate. In comparison, Papua New Guinea has a low altitude and is largely covered in tropical rainforests.

The currents around Antarctica and Papua New Guinea are different. Antarctica is surrounded by the Antarctic Circumpolar Current, which moves water from west to east around the continent. Papua New Guinea is in the Pacific Ocean, where the surface currents are primarily from east to west.

1. Describe the afternoon summer winds in coastal areas. Explain why. 2. Describe the before sunrise summer winds in coastal areas. Explain why. 3. Explain the daily summer wind conditions in the mountains. 4. Define: Katabatic Winds 5. Define: Chinook Winds

Answers

1. The afternoon summer winds in coastal areas are the sea breeze.

This is because the land heats up faster than the water, leading to the formation of a low-pressure zone over the land and a high-pressure zone over the water. The sea breeze flows from high pressure over the water to low pressure over the land, bringing cooler air from the ocean inland.

2. The before-sunrise summer winds in coastal areas are the land breeze.

This is because the land cools faster than the water at night, leading to a low-pressure zone over the water and a high-pressure zone over the land. The land breeze flows from high pressure over the land to low pressure over the water, bringing cooler air from the land out to sea.

3. The daily summer wind conditions in the mountains are characterized by upslope winds during the day and downslope winds at night.

This is because the mountains heat up faster than the surrounding areas during the day, leading to the formation of a low-pressure zone over the mountains and a high-pressure zone over the surrounding areas. The upslope wind flows from high pressure over the surrounding areas to low pressure over the mountains, bringing cooler air from the surrounding areas up the mountain.

4. Katabatic Winds are cold winds that blow down from high elevations.

They are caused by the cooling of air as it flows downhill, leading to a high-pressure zone at the top of the slope and a low-pressure zone at the bottom. These winds can be strong and can cause significant damage and disruption to local ecosystems.

5. Chinook Winds are warm, dry winds that blow down from the mountains.

They are caused by the warming of air as it flows downhill, leading to a low-pressure zone at the top of the slope and a high-pressure zone at the bottom. These winds can have significant effects on local weather patterns and can cause rapid changes in temperature and humidity.

e) Briefly describe the important aspects of the fault valve behaviour in the formation of mesothermal ore deposits. Focus your answer on fluid and confining rock pressure. What is the most important change that occurs during fault slip that allows the precipitation of precious metals such as gold from a fluid? [3 marks]

Answers

Fault valve behavior in the formation of mesothermal ore deposits is influenced by fluid and confining rock pressure. During fault slip, the most important change that occurs is the dilation of the fault zone, which allows the precipitation of precious metals like gold from a fluid.

In the formation of mesothermal ore deposits, fault valves play a crucial role in controlling fluid flow and the deposition of precious metals. A fault valve refers to the opening and closing behavior of a fault zone in response to changes in fluid and confining rock pressure. When the fluid pressure within the fault zone exceeds the confining rock pressure, the fault valve opens, allowing the fluid to flow through the fault zone. Conversely, when the confining rock pressure exceeds the fluid pressure, the fault valve closes, restricting fluid movement.

During fault slip, the shear stress acting on the fault zone causes dilation, creating interconnected fractures and opening up pathways for fluid migration. This dilation of the fault zone enables fluids, which are typically rich in elements such as gold, to infiltrate the fractures and migrate through the fault zone. As the fluid moves along the dilated fault, changes in temperature, pressure, and chemical composition can trigger the precipitation of valuable minerals, including gold.

The dilation of the fault zone during fault slip is crucial for the formation of mesothermal ore deposits. It provides the necessary conditions for the interaction between fluids and host rocks, leading to the deposition of precious metals. Understanding the behavior of fault valves and their relationship with fluid and confining rock pressure is essential for exploring and exploiting mesothermal ore deposits.
