Question

Which layer of the atmosphere is the hottest?

A) troposphere

B) stratosphere

C) mesosphere

D) thermosphere

Answer 1

D

Step-by-step explanation:

It extends from 80 kilometers above the surface of the Earth up to 600 kilometers and can heat up to 1,500 degrees Celsius because it’s very sensitive to solar activity.

Answer 2

Answer: Thermosphere

Explanation: Because there are relatively few molecules and atoms in the thermosphere, even absorbing small amounts of solar energy can significantly increase the air temperature, making the thermosphere the hottest layer in the atmosphere. Above 124 mi (200 km), the temperature becomes independent of altitude.
