Answer to Question 1

True

Answer to Question 2

In slab-pull, the subducting cold slab of lithosphere pulls the rest of the plate along as it descends into the asthenosphere. Ridge-push occurs because oceanic ridges are higher than the surrounding oceanic crust. Gravity pushes the oceanic lithosphere away from ridges and toward the trenches, where it is subducted back into Earth.
