Question

The earth retains its atmosphere because ___.

• A. the value of the escape is less than the average kinetic of atmospheric molecules.
• B. the value of the escape is more than the average kinetic of atmospheric molecules.
• C. the earth rotates
• D. the earth is spherical

Answer 1

Answer: (A)

the value of the escape is less than the average kinetic of atmospheric molecules.

It absorbs harmful ultraviolet radiation from the sun, helps keep Earth's surface warm via the greenhouse effect, and reduces temperature extremes between day and night., although some of Earth's atmosphere is escaping to space, most is staying here.
