Which of the following explains the greater depths of oceans away from the mid oceanic ridge?

Convergent boundary occurs when two plates are pushing toward each other. Which of the following explain why continental crust does not subduct beneath another continental crust during collision?

Which theory of plate movement occurs as oceanic crust moves away from the mid-ocean ridge and becomes cooler and denser, sinking into a trench?
