What is the Earth made of?

The Earth is made of rock, metal, and water. It has different layers inside it, like the crust, mantle, and core. The crust is the thin outer layer where we live, and below it is the mantle, which is hot and thick. The center of the Earth, called the core, is very hot and made of metal.

Example: When you dig in the dirt, you can find soil and rocks from the Earth's crust. These are part of what makes up our planet!

Fun Fact: The Earth is like a giant ball made of many different materials, all working together to create the world we know!
