The Atmosphere: Upper Layers of the Atmosphere

The video explains the different layers of Earth's atmosphere, focusing on the stratopause, mesosphere, and thermosphere. The stratopause separates the stratosphere from the mesosphere, which protects Earth by burning up meteors. The mesosphere is extremely cold, while the thermosphere is very hot, reaching temperatures that can melt steel. The thermosphere is further divided into the ionosphere and exosphere.
