Exploring the Atmosphere: Earth's Protective Shield

The video tutorial explains Earth's atmosphere, which consists of five layers: troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The troposphere contains most of the air we breathe and is where weather occurs. The stratosphere protects us from the sun's harmful rays. The mesosphere is the coldest layer and slows down meteorites. The thermosphere contains satellites, and the exosphere is the outermost layer, leading to space. The video concludes with review questions about these layers.
