1271 - What are the main components of the Earth's atmosphere?

The Earth's atmosphere is like a big blanket of air that surrounds our planet. It's made up of several main components:

  1. Nitrogen (78%): This is the most abundant gas in our atmosphere.
  2. Oxygen (21%): We need oxygen to breathe and stay alive!
  3. Carbon dioxide (1%): This gas helps plants grow and keeps our planet warm.
  4. Water vapor: This is like a special kind of water that's invisible in the air.
  5. Other gases (small amounts): These include things like argon, neon, and helium.

That's the basic mix of the Earth's atmosphere!
