Exploring the Atmosphere 2

The video explains Earth's atmosphere, a complex system of five layers: troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Each layer has unique characteristics, such as temperature and particle composition. The troposphere is the densest and where weather occurs. The stratosphere contains the ozone layer, protecting Earth from UV rays. The mesosphere is the coldest, where meteors burn up. The thermosphere is hot and where satellites orbit. The exosphere is the outermost layer, where atoms escape into space. These layers have remained stable over millions of years, safeguarding life on Earth.

What is the primary function of Earth's atmosphere?

• To support the growth of plants
