879 - How does the atmosphere protect life on Earth?

The atmosphere protects life on Earth in several ways:

1. Keeps us warm: It traps heat, like a blanket, keeping the Earth warm enough for life to exist.
2. Blocks bad rays: The atmosphere shields us from the sun's strong ultraviolet (UV) rays that can harm our skin and bodies.
3. Regulates air pressure: It keeps the air pressure just right, so we can breathe easily.
4. Provides oxygen: The atmosphere contains oxygen, which we need to breathe to stay alive.
5. Protects from space: The atmosphere acts as a shield, protecting us from objects like asteroids and space debris.

Think of the atmosphere like a big protective bubble around the Earth – it helps keep us safe and makes life on our planet possible!
