plate tectonics

Plate tectonics

Plate tectonics are in our life and are on the earth today. Plate tectonics is a theory of geology that's made in order to explain, observed evidence for large-scale motions on the Earths lithosphere. These plates move about a few centimeters a year. They usually move away from each other but rarely move parallel from each other. Out of these plates there are only two types of plates, oceanic plates and continental plates. An oceanic plate is a plate below sea level, and continental plates are plates above sea level. There are very little differences between continental plates and oceanic plates. Continental plates are made of sediments and volcanic rocks which make them thick. Oceanic plates are made of a certain type of volcanic rock, which makes it thin.
For space the plates need to fight. There are three ways that the plates could win a fight. One is when the oceanic plates fights itself. This would cause one plate to give and one will go under and one will go on top. Two is when oceanic plates and continental plates fight. The oceanic plates are thinner so it will go down. And the continental plates will go up because it is thicker. Lastly the continental plates fight continental plates. These plates were so thick that if they collide they will not give up and become mountains.
