Theory of Plate Tectonics

Theory of Plate Tectonics

The surface of Earth is made of large pieces called tectonic plates. These plates move slowly over time. The theory of plate tectonics explains how these plates shift and shape the planet. The continents appear to fit together like puzzle pieces. Fossils of the same spec...

Plate boundaries are locations where tectonic plates meet. Based on their movement, they are classified into three types.

Divergent boundaries occur when plates move apart, convergent boundaries form when plates move toward each other, and transform boundaries involve plates moving horizontally past each other.

Most geological acti...
