Satellites detect relative heights of cloud by sensing different levels of long wave (infrared) radiation emitted from clouds; i. e., colder clouds are normally higher in the air, and radiate less long wave energy than warmer, lower clouds.

a. True
b. False

a. True

Explanation:

The clouds that are closer to the ground surfaces are considered to be warm clouds and those that are higher above are cool and cold clouds. And thus the clouds near the earth surface traps more heat and this is able to reflect back more of the energy potential. The cold clouds are high above and don't tarp as much as the heat from the sun.

Ibelieve the answer is c also i'm in k12 too

I'm not sure i'm sorry
