This lies deep in the Earth and surrounds the inner core with liquid.

This type of crust is denser and has twice as much iron, calcium, and magnesium.

The crust is the densest layer.

This compositional layer is made mostly of iron and some nickel. It makes up about one-third of Earth's mass.

This physical layer is in the lower part of the mantle.

The mantle is between the crust and the core.

This layer contains more magnesium and less aluminum and silicon than the crust.

These are the layers of the Earth divided by chemical composition.

This compositional layer has two types of different densities.

Mostly iron, some nickel.

________ is the outermost, solid layer of the Earth. _________ is made of two parts, but also is the outermost layer.

The Earth's core is divided into five parts.

Convection is when matter stops moving.
