How is the rock in the deep mantle SIMILAR to the rock in parts of the mantle nearest to the surface?

• They are both made from oxygen and magnesium

• Rock in every part of the mantle is moving due to convection currents

• The rock throughout the mantle is brittle (like the crust)

• The rock near the surface is cooler and denser

• The rock near the surface is sinking

• The rock in the deep mantle is hotter and less dense
