The geological theory that states that pieces of earth's lithosphere are in constant slow motion is the theory of plate tectonics.

Hey did u get the answer?

Ke reqd to move from 0 to 50 will be proportional to 50x50 or 2500. this is equal to w.  to change vel from 50 to 150 you need energy prop to 22500 - 2500 = 20,000. this corresponds to 8w.  best answer is a) . work reqd is prop to velocity squared.
