Movement of tectonic plates-higher. Volcanoes, mountains and earthquakes occur at the edges of tectonic plates-their creation depends on the direction the plates are moving.
Rockhound. Plate tectonics cause earthquakes, and volcanoes. When the plates move they built up stress and when the faults release the fault cause and earth quake. There are different types of earthquakes that happen when plate collide. The main force that makes the earth move and tectonics plates form is the outer layer of the earth called lithosphere. They are what creates mountains to become higher a â¦ nd the oceans to become wider because of the earth faults and folds. Sarahroxoutofhersox1.
