Why Is the Thermosphere so Hot?

Answer

The thermosphere is the highest layer of Earth's atmosphere, and its temperatures range between around 932-3632 degrees Fahrenheit. The thermosphere is so hot because solar radiation hits it directly, without having to go through any other atmospheric layers first. The low pressure of the thermosphere means there are fewer molecules so each molecule absorbs more radiation.
