explain the theory of plate tectonics and how they have changed earth's surface over time. include the role of plate tectonics in the creation of land-forms.

      Plate motions cause mountains to rise where plates push together, or converge, and continents to fracture and oceans to form where plates pull apart, or diverge. The continents are embedded in the plates and drift passively with them, which over millions of years results in significant changes in Earth's geography.
