Atmospheric Layers and Their Properties

The video explores the structure of Earth's atmosphere, which is divided into layers: troposphere, stratosphere, mesosphere, and thermosphere. Each layer has unique properties, such as weather phenomena in the troposphere, ozone concentration in the stratosphere, shooting stars in the mesosphere, and auroras in the thermosphere. Temperature varies with altitude, decreasing in the troposphere and mesosphere, and increasing in the stratosphere and thermosphere. The video highlights the importance of these layers in protecting Earth and supporting life.

Which layer of the Earth's atmosphere is the thickest?
