-Alfred Wegner, a German scientist, is considered the father of plates tectonics.
-Based on movement of the crust, scientists believe there are 15 separate major tectonics plates on the Earth.
-At the tectonics plates boundaries (edges) there are cracks known as faults.
-The largest tectonic plate on the Earth's crust is the Pacific Plate. It is also the tectonic plate responsible for almost 90 percent of the earthquakes in the world.
-Mountains and hills, that were not formed by a volcano show evidence of plate tectonics.
