It is believed the that the Appalachian Mountains used to reach heights of nearly 20,000 feet. Over the last 300 million years since the mountains were formed, there has been enough erosion to flatten the mountains. However, despite all of the erosion, Virginia still has its mountain ranges. Which is NOT a major cause of the erosion of the mountains? A)water run-off B)wind C)coal mining D)rain

Answers

Answer 1

Answer:

Coal mining is not a major reason for the erosion of the Appalachian Mountains.

Explanation:

The Appalachian Mountains are one of the oldest mountain chains in the world. They have formed over 300 million years ago, being one of the highest, if not the highest mountains in the world in their prime. As we can see nowadays though, these mountains are not anywhere near to being the highest, but instead have a medium and small height, depending on which part of them.

The reason that these mountains lost much of their elevation is the erosion. 300 million years is a very long time, and constantly being affected by erosion has led to gradual losing of rock layers, flattening, and having gentle slopes. The rainfall, water run-off, wind, high and low temperatures, ice, have all had their impact on the erosion of the Appalachians. Over time, in a few million years, what will be left of this mountain range would be smaller and larger hills intersected with lowlands.

Answer:

The US wanted to find out how communism was spreading so fast

Explanation:

The US knew how the USSR had become a super power, and they didn't care how the citizens were being treated. The threat of a nuclear attack was on the minds of many, but the US's main goal during the Cold War was to prevent communism from spreading, so using intelligence agents to find out how it was spreading is the best answer.

suns out put atmosphere traps heat
green house gases coldest phase of climate cycle
green house effect can vary
ice age atmosphere traps even more heat

Answers

Answer:

Sun's output - can vary

Greenhouse gases - atmosphere traps even more heat

Greenhouse effect - atmosphere traps heat

Ice age - coldest phase of the climate cycle

Explanation:

The Sun is a star, and it is constantly active. Its activity is very important when it comes to the living conditions on Earth because it can have a big climatic impact. In general, when the sun's output is higher, the Earth is warmer, when the sun's output is smaller, the Earth is colder.

Greenhouse gases are gases that have properties that enable them to trap heat. Such gases are carbon dioxide and methane. When these two gases are in a higher amount in the atmosphere, the atmosphere becomes increasingly warmer, leading to global warming.

The greenhouse effect occurs when there is a solid amount of greenhouse gases in the atmosphere. They manage to trap the heat, thus increase the temperature. By increasing the temperature in the atmosphere, the whole climate on Earth experiences changes.

Ice ages occur because of the motion cycles through which Earth goes through When all three are in place, Earth cools down. Not just that the global climate becomes cooler, but it is also much drier, while the ice caps extend significantly more toward the lower latitudes.
