What is a continental plate and how does it matter to human existence?

Earth has a moving, morphing which has lead to the evolution of life forms.

Explanation:

A continental plate or slab of rocks that form a landmass consists of lighter elements like silicon and aluminum and has a low density. It's formed by the heating and cooling of magmas over the surface is called the crust. The existence of life on earth would have not been possible if the continental plates were not formed, the earth is itself active and evolving this evolution led to the formation of the seven continent; landmasses and ocean basins as below them the earth is moving. Spreading of the lavas on ocean floor and the formation of rocks with different compositions and not only that plate tectonics have modulated the atmosphere also they are the driving creation of motion of tides and life-giving nutrients. Thus life emerged from the earth's ocean bottoms.
