Question

The thermosphere is characterized by a drastic increase in temperature. What is the reason for this increase? A. absorption of ultraviolet rays from the Sun B. decrease in moisture C. entrapment of greenhouse gases D. increase in air pressure

Answer 1

Answer:

A. absorption of ultraviolet rays from the Sun

Explanation:

The thermosphere helps protect and regulate Earth's temperature by absorbing much of the UV radiation and X-rays emitted by the Sun. When the Sun is most active, the thermosphere heats up and increases in size, increasing its protective power.

Just like in the oceans, the Earth's atmosphere experiences waves and tides that help move energy within it. The winds and the general circulation of the thermosphere are strong drivers of these tides and waves.
