Troposphere, Stratosphere, Mesosphere, Thermosphere, and Exosphere.

Thanks to these studies, we now know the five layers of the atmosphere are the troposphere, stratosphere, mesosphere, thermosphere and exosphere (see graphic). Together, these layers protect us ...

This layer helps protect us from harmful UV (Ultra Violet) radiation by absorbing most of it before it reaches the surface, ...

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 ...

Earth's atmosphere is divided into several distinct layers, each characterized by specific temperature variations, composition, and phenomena. Below are the primary layers of the atmosphere, from the ...
