Exploring the Five Layers of Earth's Atmosphere

The video tutorial explains Earth's atmosphere, which consists of five main layers: troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Each layer has unique characteristics, such as temperature variations and specific functions. The troposphere is where weather occurs, the stratosphere contains the ozone layer, the mesosphere is where meteors burn up, the thermosphere absorbs high-energy radiation, and the exosphere is the outermost layer merging into space.
