Exploring the Atmosphere

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 evolved over time but continue to protect life on Earth.

What are the five layers of Earth's atmosphere?

Describe the characteristics of the troposphere.

What is the role of the ozone layer in the stratosphere?

Explain why the mesosphere is the coldest layer of the atmosphere.

What happens to atoms and molecules in the exosphere?
