There, convection cells provide the energy necessary to split apart the crust into both large and small sections that can move relative to one another. The direct evidence for the effects of this convective origin of earth essay is the large number of volcanoes and earthquakes that occur along plate boundaries.

No one origin of earth essay certain how long plate tectonics has been a part origin of earth essay Earth history, but it is certainly responsible for the continent-ocean basin relationship, which forms the present crust.

This movement is continuous, and origin of earth essay formation of supercontinents seems to be inevitable, as is their eventual breakup. The formation of the world's great mountain chains is the direct result of colliding continents transforming marine sediment into hard rock. New crustal origni is created by volcanic activity at mid-oceanic ridges that pushes plates apart from one another.

Such plate movement can also carry older, crustal rock to its destruction in an oceanic trench or be welded together into a new continental mass. Where did life on earth originate?
