Plate Tectonics

The plate tectonics theory is that the earth's outer shell consists of individual plates that interact in many ways and they produce volcanoes, mountains, earthquakes, and the crust. Evidence to the plate tectonics theory is Paleomagnetism which is the magnetic field that has a north and a south pole that align closely. Ocean drilling which is drilling into the ocean floor sediment. And Hot spots is a mapping of the seafloor volcanoes in the pacific which revealed a chain of volcanic structures.

Continental drift starts together and eventually drifts apart and instead of drifting through the plates it goes through the ocean floor.

Plate tectonics started off scattered and came together.
