Here's the correct order of Earth's layers starting from the surface:

1. Crust: This is the outermost, thinnest layer, composed of relatively light rock. It's broken into tectonic plates that move and interact.

2. Mantle: The thickest layer, mostly solid but with a semi-molten layer called the asthenosphere. This is where convection currents drive plate tectonics.

3. Outer Core: Liquid iron and nickel, generating Earth's magnetic field.

4. Inner Core: Solid iron and nickel, extremely dense and hot.

Let me know if you want more detail about any of these layers!
