Answer:
Explanation:
Climate can be affected by many factors. On the west coast of South America in Peru, many Peruvians depend upon the fishing industry. Fishermen find a wealth of fish in the cool nutrient-rich Pacific waters. Occasionally, these same nutrient-rich waters warm up, and the fish disappear. When this has happened, the fishermen would be temporarily out of work, but this warming does not last, and then the waters would return to normal with abundant schools of fish. This ocean warming phenomenon would often occur near Christmas, so the fishermen started referring to these warming events as El Niño. In Spanish, El Niño is short for “El Niño Jesus” meaning “the child Jesus.” Scientists have continued to use the term El Niño for this change in ocean temperature. El Niño has been part of life for Peruvian fisherman for hundreds of years, but the global atmospheric affects of El Niño events have only recently come to the attention of atmospheric scientists. In the past twenty years, the “no fish” periods off the coast of Peru began to last longer, causing a serious disruption in the fishing industry of Peru. Scientists began to take note of this problem, and since then research seems to be indicating that a correlation seems to exist between El Niño events and global warming. Scientists began to wonder whether the El Niño events were the cause of global warming, or, whether global warming was the cause of the longer El Niño events. In the following activity you will explore the data and have a chance to consider the nature and the effects of El Niño events.
These natural cycles have, in the past, resulted in regional and global climates that are very different than our climate today. These natural influences are still at work but have recently been overshadowed somewhat by the influences of human-produced greenhouse gases.
The Milankovitch cycles relate to the effect that the Earth’s positioning with respect to the sun has on the Earth’s climate.There are three Milankovitch cycles:
eccentricity (orbit)
obliquity (tilt)
precession (wobble)
We also take a look at changes in radiation from the sun
The Earth’s orbital patterns are always changing. This variation follows cyclical patterns that take thousands of years to repeat. The point the Earth is at in the cycle changes the distribution of solar radiation, and therefore, cooling or warming in different parts of the world.
The amount and distribution of solar energy that Earth has received (due the Earth’s natural orbital variations) is thought to be responsible for triggering major climate epochs in the past, such as ice ages.

In most classification schemes, which principal indicator is used to
delineate five zones and their subtypes?
Cloudiness
Temperature
Daylength
Precipitation
Vegetation types
Answer:
Vegetation types
Explanation:
In the case of biomes, which are perhaps the most commonly used classification scheme in physical geography, vegetation is the principal indicator to delinate the different zones and their subtypes.
Even if both vegetation and fauna define a biome, and a sub-biome, because vegetation is more pervasive than fauna, it becomes the principal indicator in practice.
The correct answer is E. Vegetation types
Explanation:
In geography, the zones around the world are classified into five main types: the tropical zone, the Arctic, the Antarctic, the South temperate zone, and the North temperate zone. These zones are determined by two main factors, the first one is the latitude, for example, the tropical zone is near the equator line, and the second one is the vegetation that is different in each zone. For example, the Arctic and Antarctic zones differ from others because the vegetation is not abundant and includes mainly grasses and mosses; on the opposite, in the tropical zone, the vegetation is abundant including diverse grasses, shrubs, and trees. At the same time, it is vegetation the key to determining sub-type zones. Thus, one principal indicator used to delineate the five zones is vegetation types.
Chinese cities will be submerged underwater
Answer:
You have posted a statement and not a question
Explanation:
Explanation:
China produces more carbon dioxide emissions than any other country, and its coastal cities will be dramatically affected by rising seas as the atmosphere warms, according to a November report by Climate Central, a nonprofit organization.
Barring large amounts of spending on shoreline barriers and flood control systems, these images show what China would face if carbon emissions cause global temperatures to rise by 2° Celsius (3.6°F), the current international target by 2100, or by 4° Celsius (7.2°F), roughly the warming predicted if no action is taken to curb emissions.
Shanghai
China's largest city, with a population of around 24 million at the edge of the East China Sea, has the most to lose from rising sea levels. Climate Central estimates that 76 percent of the Shanghai region's current population lives in areas that would eventually be underwater if the Earth warms by 4°C by 2100.

Tianjin has a lower elevation than its larger neighbor Beijing, and the city proper is home to about 11 million people. The rising waters created by a 4°C temperature increase would submerge about 29 percent of the area’s current population.

Shantou
The large southern port city of Shantou sits on a river delta surrounded by mountains, making it vulnerable to the encroaching ocean. Fifty-four percent of the current population lives below where sea level would end up following a 4°C warming scenario, in contrast to 22 percent for a 2°C increase.

Note: Because the elevation data used to model inundation tends to over-estimate the height of urban areas, rising seas would likely cover more than is shown on the map. Because of the difficulty of estimating how quickly ice will melt, the scenarios shown could develop over the course of several centuries.
What do we call the form of weathering that involves temperatures fluctuating around 0°C and is the dominant mechanical weathering process on coastlines?
Answer:
Freeeze-thaw weathering
Explanation:
Freeze- thaw weathering involves the breakdown of rock particles into smaller fragments through continuous fluctuations in the temperature of the water bodies. This form of weathering is common along coastlines. The water enters the rocks and then freezes when there is a decrease in temperature. The freezing expands the rock particles and aids frictions between the rock parts. This helps in the breakdown of the rocks to smaller particles.
It involves temperatures fluctuating around 0°C and is the dominant mechanical weathering process on coastlines

Match the term in column 1 to the characteristics in column 2.
Column 1:
a) Mass wasting
b) Heating and cooling
c) Dust bowl
d) Oxidation
Column 2:
1) Severe farmland erosion
2) Type of physical weathering
3) Type of chemical weathering
4) Landslides or other collapses
Answer:
a) Mass wasting - 4) Landslides or other collapses
b) Heating and cooling - 2) Type of physical weathering
c) Dust bowl - 1) Severe farmland erosion
d) Oxidation - 3) Type of chemical weathering
Explanation:
a) Mass wasting is defined as the slope movement which causes the downslope of soil, sand, and rock under the influence of the force of gravity. So, mass wasting causes landslides and other collapses due to slope movement.
b) Heating and cooling or temperature changes is a type of physical weathering. Rocks expand at high temperatures (Hot) and contracts at lower temperature (Cool).
c) Dust bowl : When grasses in farmlands are not tightly rooted, the eroding soil led to massive dust bowl and blow the grasses in the farmlands.
d) Oxidation is a type of chemical weathering. Oxidation is defined as the reaction of a substance with oxygen, when oxygen reacts with rocks and soil, it forms oxides which result in weathering.
Hence, the correct answer is:
a) Mass wasting - 4) Landslides or other collapses
b) Heating and cooling - 2) Type of physical weathering
c) Dust bowl - 1) Severe farmland erosion
d) Oxidation - 3) Type of chemical weathering
Answer:
a) Mass wasting - 4) Landslides or other collapses
b) Heating and cooling - 2) Type of physical weathering
c) Dustbowl - 1) Severe farmland erosion
d) Oxidation - 3) Type of chemical weathering

What was important about Timbuktu’s location?
Answer:
Explanation:
Located near the Niger river in Mali, West Africa, on the edge on the Great Desert, Timbuktu was established in the year 1100 by the Tuareg people, it was know for a hundreds of years as key trading post of the ancient Mali Empire (1235 to 1670 C.E.) Sub-Saharan caravans would trade gold, slaves, ivory, silver and stock up with water and then go into the Sahara Desert to get to the Mediterranean Sea from the heart of Africa.
