Despite being trapped in the middle, the mesosphere is the coldest layer of Earth's atmosphere, with temperatures as low as -130F (-90C) at the very top of the mesosphere. This is because the ...

The temperature can change from very hot to very cold, depending on sunlight exposure. It can range from 1,700°C (3,092°F) in the sun to -270°C (-454°F) in the shade.

I like to think of the atmosphere as sort of a big sandwich since the atmosphere isn't just one layer. It has many distinct layers from the ground all the way into space. This means the ground and ...

Over time, they noticed that the atmosphere had distinct layers. By the early 1900s, scientists had identified major layers of the atmosphere based on how the temperature changed at different ...

is cold, and if heat from the sun is warming the atmosphere by radiation, one may expect the outer layers to be warm and the lower layers to be the coldest ones. If, however, there are ...
