What is Earth’s atmosphere made of?

What are the 7 layers of atmosphere?

Layers of the atmosphere

  • The Troposphere. This is the lowest part of the atmosphere – the part we live in.
  • The Stratosphere. This extends upwards from the tropopause to about 50 km.
  • The Mesosphere. The region above the stratosphere is called the mesosphere.
  • The Thermosphere and Ionosphere.
  • The Exosphere.
  • The Magnetosphere.

What is the atmosphere like on Earth?

Earth’s atmosphere is composed of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.1 percent other gases. Trace amounts of carbon dioxide, methane, water vapor, and neon are some of the other gases that make up the remaining 0.1 percent.
