4.12 Quiz: Energy of Convection Pool 2
Question 2 (1 point)
What two forces influence the movement of Earth's plates?

Question 2 options:

magnetism and convection

convection and gravity

fluids and temperature

gravity and solar heat
Question 3 (1 point)
How can gravity's role in tectonic plate motion be described?

Question 3 options:

Question 4 (1 point)
What is slab pull?

Question 4 options:

cooler, denser crust sinks into the mantle

when edges become denser and gravity pulls them downward and away from one another

currents just beneath Earth's crust flow very slowly, causing movement in the plates above them

folding and crumpling and sliding upward creating mountains

Question 5 (1 point)
What is ridge push?

Question 5 options:

cooler, denser crust sinks into the mantle

when edges become denser and gravity pulls them downward and away from one another

currents just beneath Earth's crust flow very slowly, causing movement in the plates above them

folding and crumpling and sliding upward creating mountains
