Question

the average temperature of the earth's atmoshphere has decreased​

Answer 1

Answer:

Hello....

Explanation:

On the average, it extends 11 km to the top of the troposphere which is called the tropopause. In the troposphere, the temperature generally decreases with altitude. The reason is that the troposphere's gases absorb very little of the incoming solar radiation.

The farther away you get from the earth, the thinner the atmosphere gets. The total heat content of a system is directly related to the amount of matter present, so it is cooler at higher elevations.

Answer 2

Explanation:

This absorption and radiation of heat by the atmosphere—the natural greenhouse effect—is beneficial for life on Earth. If there were no greenhouse effect, the Earth's average surface temperature would be a very chilly -18°C (0°F) instead of the comfortable 15°C (59°F) that it is today.
