Chapter 6: Problem 670

The atmosphere is held to the earth by (A) clouds (B) Gravity (C) Winds (D) None of the above

Short Answer

Expert verified
The correct answer is (B) Gravity, as it is the force that attracts objects with mass towards each other, keeping the atmosphere close to Earth's surface.

Step by step solution

01

Understand the atmosphere

The atmosphere is the layer of gases surrounding the Earth that is held in place by Earth's gravity. It is composed mainly of nitrogen, oxygen, and trace amounts of other gases. The primary purpose of the atmosphere is to protect life on Earth, absorb sunlight, and maintain temperature balances. It consists of various layers that extend several thousand kilometers above Earth's surface.
02

Evaluate Option (A) Clouds

Clouds are formed from water droplets or ice crystals that condense in the atmosphere. While they are a crucial part of Earth's weather system, they do not have the ability to hold the entire atmosphere in place. As such, option (A) is not the correct answer.
03

Evaluate Option (B) Gravity

Gravity is the force that attracts two objects with mass toward each other. In the context of the atmosphere, Earth's gravity pulls the gases closer to its surface, which in turn keeps it from escaping into outer space. This force is strong enough to hold the entire atmosphere in place. Thus, option (B) is the correct answer.
04

Evaluate Option (C) Winds

Winds are the movement of air caused by differences in pressure within the atmosphere. They can indeed move and distribute certain elements within the atmosphere, but they lack the strength to hold the entire atmosphere in place. Therefore, option (C) is not the correct answer.
05

Evaluate Option (D) None of the above

We have already determined that gravity (option B) is responsible for holding the atmosphere to the Earth. Therefore, none of the above (option D) cannot be the correct answer. #Conclusion#: The correct answer to the question of what holds the atmosphere to the Earth is (B) Gravity, as it is the force that acts on all masses to keep them close to each other, and in this case, keeps the atmosphere close to the surface of the Earth.
