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

• crust has no motion

• crust moves in random directions

• crust moves in same direction convection cycle moves

Which of the following best describes mantle convection?

• The process by which heat is transferred through the vacuum of space

• The movement of tectonic plates due to the flow of molten rock in the mantle

• The solidification of magma at the Earth's surface

• The cooling of the Earth's crust

Evaluate the impact of mantle convection on the Earth's surface features.

• It has no impact on surface features

• It leads to the formation of oceanic ridges and trenches

• It causes the Earth's surface to cool rapidly

• It results in the erosion of mountains

How does the temperature of the Earth's mantle affect mantle convection?

• Higher temperatures increase the viscosity of the mantle

• Higher temperatures decrease the viscosity of the mantle

• Temperature has no effect on mantle convection

• Lower temperatures increase the rate of convection
