Answer:
The closer the rocks are to the mid-ocean ridge the younger they are, and the further away they are the older they are.
Explanation:
The ocean floor gives us one of the best if not the best evidence for the movement of tectonic plates, and definitely the best when it comes to ocean floor spreading. When the convection currents are stronger at parts, they manage to break up tectonic plates, moving them apart, and gradually forming an ocean.
The magma that is pushed through the gap is quickly cooling off and solidifies into a new rock on the ocean floor. Because magma keeps coming constantly for millions of years, the new rock that forms constantly pushes away the preexisting rock. This leads to a situation where the youngest rocks are always found at the mid-ocean ridge because it is there where they form. The further a rock is from the mid-ocean ridge the older it is. The oldest rocks are found at the edges of plate boundaries that are on the opposite sides of the mid-ocean ridge, and they often tend to be a subject of subduction.
It protects life from the damaging rays of the Sun. Also provides air for life as well.
