Trace fossils represent fossilized behavior and usually do not include any of the original organic material. Identify the trace fossils in the images by dragging the labels to the correct location.
a) footprints
b) feeding marks
c) burrows
d) coprolites

Answers

Answer:

1. d) coprolites, 2. b) feeding marks, 3. a) footprints, 4. c) burrows

Explanation:

Trace fossils are those that have a fossil record of the biological activity and not the preserved parts of the plants and are usually altered by the later chemical activity or mineralization. A coprolite is a fossilized feace and are opposed to the body fossils and is evident from the behaviour of the animals and formed in different shapes and compose of animal dung. The feeding marks are the longest and deepest tooth marks left by carnivorous dinosaurs. Burrows in a fossil is the remains of the holes and tunnels excavated into the ground or the seafloor. The footprints are the tracks that are left by the ancient animals upon the sedimentary rocks.

Essay 1.Why rural settlements have declined 2.reasons why city dwellers opt for the country 3.Benefits of living in the country 4.impact on the rural economy

Answers

Answer:

1.Why rural settlements have declined

Rural settlements have declined because they offer less economic opportunities. In rural areas, the basic activity is agriculture, which tends to pay less than manufacturing or services, and that, due to mechanization, needs less workers every decade.

2.reasons why city dwellers opt for the country

Sometimes city dwellers opt to move out for the country either because they find employment there, or can work remotely, Living in the country is usually cheaper than living in the city, and can also be more desirable to many people who prefer a quiet enviroment.

3.Benefits of living in the country:

As said above, one benefit is in lifestyle: the country is quiet, calm, and cheap. It has higher quality air, and less polution overall. Many people also find small country communities more socially desirable than the large communities that can be found in cities.

4.impact on the rural economy

City dwellers moving for the country benefits the rural economy. City dwellers bring their incomes, and they support the local community businesses. New comers can also help revitalize areas whose population is dwindling.

What were the first two great continents in continental drift

Answers

What were the first two great continents in continental drift

Pangea, the last supercontinent formed some 360 ​​million years ago by the grouping of all existing continental masses, begins to separate 130 million later, during the transit between the Permian and Triassic, and it does so by fragmenting into two major continents:

One, which begins to drift north and is called Laurasia, and another, which drifts south, called Gondwana. These two great continental masses are separated by the Neotethys ocean.

Laurasia will subsequently fragment and give rise to what will be Eurasia and North America, while the rest of the continents will separate from Gondwana: South America, Africa, Antarctica and Indoaustralia, which in turn will break, giving rise to the Indian and Australian subcontinents.

A volcano that has not erupted in a very long time suddenly has a plume of steam coming from it. Which best describes this volcano? was dormant and is now active was quiet and is now active was extinct and is now explosive was dormant and is now explosive

Answers

Answer:

A

Explanation:

It was dormant and is now active best describes the volcano. There are three types of volcanoes: active, dormant, and extinct. Thus, option A is correct.

Active volcanoes have recently erupted; they are likely to do so once more. Volcanoes that are dormant have not erupted in a very long time but could do so in the future. It seems unlikely that extinct volcanoes will erupt in the near future.

Thus, Magma, or molten rock, accumulates in a chamber inside an active volcano. The magma escapes onto the surface of the planet through channels in the rock as a result of pressure building up inside the magma chamber. Lava is the name given to magma once it spills onto the surface.

Thus, A is the ideal selection.

B. A surveyor provides close readings of soil decomposition.
C. A surveyor provides close readings of land elevations.
D. A surveyor provides detailed descriptions of flora and fauna.

Answers

The correct answer is C. A surveyor provides close readings of land elevations.

Explanation:

One of the main focuses of geography is to study land features including relief or elevations. This is possible through main experts including surveyors who survey the land, which implies observing and measuring the land to record its features and elevations. Additionally, the information collected by surveyors is later used by other experts to create maps or even to compare how the land changes over time. Thus, the role of a surveyoR is to provide close readings of land elevations (Option C.)

What is a Climate?

Climate is determined by a region’s climate system. A climate system has five major components: the atmosphere, the hydrosphere, the cryosphere, the land surface, and the biosphere.

Climate is the long-term pattern of weather in a particular area. Weather can change from hour-to-hour, day-to-day, month-to-month or even year-to-year. A region’s weather patterns, usually tracked for at least 30 years, are considered its climate.

Explanation:

Native species of North America are often defined as those species that were present in North America before Europeans arrived in the early 1600s. When Europeans arrived, they found extensive forests dominated by the American chestnut tree. These chestnut trees were extensively cultivated and planted by the North American natives for food and other wood products. In the early 1900s the chestnut blight (a fungus) virtually exterminated all of the American chestnut trees from North America.

(a) Is the American chestnut considered a native species despite its intensive cultivation? Explain why.

(b) Is the chestnut blight considered a native or invasive species? Explain why.

(c) Discuss why invasive species tend to proliferate at very high rates.

(d) Many people are trying to grow hybrid chestnut trees that will be immune to the chestnut blight so that forests can be restored to those found by the Europeans in the 1600s. Do you agree or disagree that this should be done? Justify your answer

Answers

Answer:

a) Yes! the American chestnut tree is a native species. The American chestnut tree was present before the Europeans arrived in North America in the 1600s. Since a native species has been defined as any species that was present in North America before the arrival of the Europeans, then it is a fact that the North American chestnut tree is a native species.

b) The chestnut blight is an invasive species that is native to east East Asia, and was accidentally introduced into North America around the early 1900s, when the Japanese chestnut was commercially cultivated in the United States.

c) Invasive species tend to proliferate at a very high rate because they lack some natural constraints in the new environment such as natural predators, competition, and as in the case of this chestnut blight; the host has no natural defense mechanism against them. These conditions allow them thrive more than they would in their natural environment, unchecked

d) Yes, I agree with this idea, albeit to some extent. The development of hybrid chestnut resistant to the chestnut blight will possibly return the forests back to how it was before the Europeans arrived in the 1600s, but the genetic conservation will be altered, since these new trees will be an hybrid of the old trees, and the forest won't truly be as it was before the 1600s

Explanation:

Private student loan is an option for financing which is meant for higher studies from college or bank for student education. This type of loan is available to any student who meets learning standards but do not allow for income-driven repayment plans. There is also no student loan forgiveness. Credit check is required in this type of loan financing so as to know whether the student has loan elsewhere and whether he is up to date in terms of repayment.

Once the loan has been taken, one can start paying up but there is a grace period of six months within which repayment must be fully made. The loan can be refinanced, no borrowing rates, have variable interest rate, hence no interest ceiling.

Humans and their close relatives (hominins) have been around for roughly 5 million years. What percentage of geologic time is represented by the history of this group?

Answers

Answer:

Approximately 0.11% of the geological time.

Explanation:

Evidence from radiometric dating indicates that Earth is about 4.54 billion years old.

If humans and their close relatives (hominins) have been around for roughly 5 million years, the the fraction of this time to the geological time is calculated below

4.54 billion years = 4.54 x 10^9 years

5 million years = 5 x 10^6 years

percentage = [tex]\frac{5*10^{6} }{4.54*10^{9} } *100%[/tex] ≅ 0.11% of the geological time.

During summer, cities located near the coast are ________ than those in the interior at the same latitude, while in the winter they are ________. Group of answer choices

Answers

Answer:

During summer, cities located near the coast are cooler than those in the interior at the same latitude, while in the winter they are warmer.

The reason for this climate is the proximity to the sea and its large masses of water that bind thermal energy. In winter, the sea works warming and in summer cooling. The humidity prevents really low temperatures because heat is released when the water vapor condenses. However, the weather often varies as the impact can come more from the sea or more from land depending on the movement of the weather systems.

The term "geographical region" refers to a particular location on the globe. Latitude and longitude are the two parameters that determine your exact physical region. Relative position, on the other hand, describes one place in relation to another.

Cities near the shore are colder in the summertime than those in the hinterland at the very same latitude, and milder in the winter.

The closeness to the sea and its enormous quantities of water that bind heat energy is the cause of this climate. The ocean heats in the winter and cools in the summer. Because heat is generated when water condenses, humidity prevents extremely low temperatures.

The weather, on the other hand, is frequently unpredictable, as the impact might come more from the water or more from the land, depending on how the weather patterns shift.

Answers

Answer: 9.25°C

Explanation:

As you move higher from sea level, the temperature drops at an average rate. This average rate at which the temperature drops is known as the lapse rate.

This rate is 6.5 °C per 1000 m.

Temperature at 5,500m has dropped by;

= 6.5 * [tex]\frac{5,500}{1,000}[/tex]

= 35.75 °C

Temperature has decreased by 35.75 °C.

Temperature at 5,500m above sea level is;

Answers

-Seasonality of volume of water;Some rivers have very high volume of water during the wet season but very low volume of water during the dry season
-Presence of rapids and waterfalls like Rippon falls on R.Nile hinders movement of vessels
-Some rivers eg Nzoia and Yala are too short and narrow making movement of vessels difficult ----floating vegetation like sudd on parts of R.Nile hinder navigation
-Silting at rivers mouths for example on R.Athi, R.Tana and R.Rufiji hindering movement of vessels

Africa is the second large continent after Russia and is home to a large number of rivers. But most of these rivers are not navigable due to they have waterfalls and are seasonal in nature.

Africa has a large natural resource base but suffers from a shortage of infrastructure and development. Most of the African land is under corruption and is politically unstable.  Most of the wars are due to power, political conflicts, and lack of developmental projects and financial constraints. Hence transportation through most of rivers is a big problem for people.
