Question

Temperature of troposphere decreases with altitude. This is because of_____.

• A. high pressure of air
• B. gases present in air
• C. low density of air
• D. all of these

Answer 1

Answer: (A)

high pressure of air

Generally, temperatures decrease with increasing height because the atmosphere distributes itself according to gravity.

In the troposphere, the temperature generally decreases with altitude. The reason is the troposphere's gases absorb very little of the incoming solar radiation. Instead, the ground absorbs this radiation and then heats the tropospheric air by conduction and convection.
