Back

Each system has a specific function and they work together to support life and natural processes.

Earth's Inner Layers

Back

1. Continental crust 2. Oceanic crust 3. Lithosphere 4. Lower mantle 5. Outer core 6. Inner core

Front

Continental Crust

Back

The layer below the land surface.

Front

Oceanic Crust

Back

The layer below the sea floor surface.

Front

Lithosphere

Back

The crust and upper mantle that can be moved by the layers below.

Front

Lower Mantle

Back

Warmed from the outer core, can make convection currents.

Front

Outer Core

Back

Liquid, keeps layers above in motion, causes convection currents.

Front

Inner Core

Back

Most dense layer, solid and full of pressure.

Front

Plate Tectonics Theory

Back

Earth's surface is made of rigid slabs or plates that move with respect to each other.
