The Structure of the Atmosphere

The video explains the Earth's atmosphere, detailing its composition and the distinct layers: troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Each layer has unique characteristics affecting temperature, pressure, and weather phenomena. The troposphere is where weather occurs, while the stratosphere contains the ozone layer, protecting Earth from UV radiation. The mesosphere burns up meteorites, creating shooting stars. The thermosphere hosts the International Space Station, and the exosphere is where satellites orbit. The ionosphere, spanning multiple layers, is crucial for auroras and radio communication.
