That is because its outer surface is composed of about 20 tectonic plates, enormous sections of Earths crust that roughly fit together and meet at places called plate boundaries.Plate boundaries are important because they are often associated with earthquakes and volcanoes.

The North American plate is moving to the west-southwest at about 2.3 cm (~1 inch) per year driven by the spreading center that created the Atlantic Ocean, the Mid Atlantic Ridge. When the plates of the outer layer move, there are places were the mantle is exposed to the air and water at the surface. Scientists think that this movement is related to the differences in strength along the earth's crust, rather than the mantle's activity beneath. For example, sections of Earths crust can come together and collide (a convergent plate boundary), spread apart (a divergent plate boundary), or slide past one another (a transform plate boundary). Earth's plates move on top of a soft, solid layer of rock called the mantle.
