111 - What are the main layers of the Earth?
Imagine the Earth like an onion with layers. There are 4 main layers:
- Crust: The outer layer, where we live. It's thin and rocky.
- Mantle: Under the crust, it's thick, hot, and made of slow-moving rocks.
- Outer Core: A liquid metal layer, where the Earth's magnetic field is made.
- Inner Core: The center of the Earth, a solid iron ball that's really hot.
These layers work together to make our planet the way it is.
