Plate Tectonics

Plate Tectonics 

Theory of Plate Tectonics: the crust that breaks apart into section of plates on top of the liquid menthol

Tectonic Plates: A section of the plate or crust.

Convection Currents: the movement of magma that makes plates move.

Summary

Plate Tectonics is the theory that the Earths outer shell is divided into several plates that move over the mantle. the plates act like hard shells. the convection currents cause movement of magma that makes plate move.

Questions

1. What type of boundaries are there?
There are three kinds of plate tectonic boundaries. divergent, convergent, and transform plate boundaries
2. what is oceanic crust and what is continental crust difference?
Oceanic crust is under the water and it is composed of basalt rock, continental crust is on land and is made up of granite rock.
