Layers of the Earth Worksheet - Free Printables - Free Printable

Let’s solve this step by step.

We are looking at a diagram of the Earth cut in half, showing its layers from the outside to the inside. There are five blank boxes pointing to different parts of the Earth’s interior. We need to match each layer with the correct name from the Word Box.

The Word Box gives us these terms:
- Crust
- Upper mantle
- Lower mantle
- Outer core
- Inner core

Now let’s think about the order of Earth’s layers — starting from the surface and going inward:

1. The very outermost layer is the Crust — that’s where we live, on top of the ground or ocean floor.
2. Just below the crust is the Upper mantle — it’s solid but can flow slowly over time.
3. Below that is the Lower mantle — deeper and hotter, still mostly solid.
4. Then comes the Outer core — this is liquid metal (mostly iron and nickel).
5. At the very center is the Inner core — super hot, but so much pressure that it’s solid metal.

Looking at the diagram:

- The top box points to the thin outer layer → that’s the Crust
- The second box points to the next layer down → Upper mantle
- The third box points to the layer beneath that → Lower mantle
- The fourth box points to the layer after that → Outer core
- The bottom box points to the very center → Inner core

So, filling in the blanks from top to bottom:

Top box: Crust
Second box: Upper mantle
Third box: Lower mantle
Fourth box: Outer core
Bottom box: Inner core

Final Answer:
From top to bottom: Crust, Upper mantle, Lower mantle, Outer core, Inner core
