Ummmm????? what does this question mean????
1) heat from radioactive decay in the core of the Earth heard the mantle.
2) Plates move averagely only a few cm a year, this has been happening ever since the planet formed and cooled to give a thick crust so this movement has added up over many years to move plates far from where they started.
3) because the mantle is heated and is able to flow slowly, convection currents are set up which cause the plates on the crust to move.
Answer:
One side of the moon always faces the earth, which is called synchronous rotation. In other words, the length of time the moon rotates or revolves around its axis is the same as the length of time it takes to orbit the earth... Therefore, our moon always has a side facing the earth, which we call the near side of the moon.
I think the answer is d not a 100 % sure
