Atmospheric Layers and Their Functions

The video explores the Earth's atmosphere, highlighting its protective role and composition. It details the five layers: troposphere, stratosphere, mesosphere, thermosphere, and exosphere, explaining their unique characteristics and importance. The troposphere hosts weather phenomena, while the stratosphere contains the ozone layer. The mesosphere is the coldest layer, where meteors burn up. The thermosphere is the warmest, home to the ISS and auroras. The exosphere marks the boundary with space, containing satellites. The video emphasizes the atmosphere's crucial role in sustaining life.
