The high temperatures in the thermosphere occur because
A)infrared radiation from the ground heats this layer more than any other layer.
B)methane is such an effective greenhouse gas.
C)carbon dioxide has accumulated to very high levels in this layer.
D)it is in direct contact with high energy solar radiation.
E)high intensity solar radiation causes strong chemical reactions with ozone,and this heats the layer to very high temperatures.

Question

Quizplus · Accepted Answer

The high temperatures in the thermosphere are caused by direct contact with high energy solar radiation. The thermosphere is the layer of the Earth's atmosphere located above the mesosphere, and it receives the highest levels of solar radiation. This solar radiation heats the gases in the thermosphere, causing them to reach very high temperatures.
