Why is the inner core solid if the outer core is liquid?

• It is made of solid rock

• it is located directly below the mantle

• it is affected by pressure from the layers above it

Why is the inside of the earth divided into layers?

• The layers are all solid.

• The layers are all the same temperature.

• The inside is divided into layers but, they are all alike.

• The inside of the earth is divided into layers because they are all different temperatures and densities.

The continental crust floats on top of the mantle because the crust is

• less dense than the mantle.

• made of a liquid material.

• made up of oxygen which is a light element.

• separated from the mantle by a layer of water.
