Question

Which two layers of the atmosphere are characterized by decreasing temperatures with increasing altitude?

A
troposphere, mesosphere

B
stratosphere, thermosphere

C
troposphere, thermosphere

D
stratosphere, mesosphere

Answer 1

A troposphere, mesosphere

Step-by-step explanation:

Temperature decreases with altitude in two of Earth's atmospheric regions: the troposphere and the mesosphere. The troposphere is the region closest to the ground, and the mesosphere is just above the ozone layer.

Answer 2

A

Step-by-step explanation:

The troposphere gets its heat from the ground, and so temperature decreases with altitude. Warm air rises and cool air sinks and so the troposphere is unstable. In the stratosphere, temperature increases with altitude. The stratosphere contains the ozone layer, which protects the planet from the Sun's harmful UV.
