Which statement is correct?

• As you move up through the layers, the pressure increases.

• As you move down through the layers pressure increases.

• As you move down through the layers, pressure decreases.

• As you move up down through the layers, pressure remains the same.

The plates of the crust move because...

• volcanoes erupt violently.

• of the weight of the oceans.

• of convection currents in the mantle.

• of the moon's gravity.

Convection currents move in the mantle. How does this affect the crust?

• crust moves in random directions

• crust moves in same direction convection current moves
