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
