What are Plate Tectonics
Plate tectonics is the theory that Earth's top layer is divided into several plates that glide over the mantle. The theory of Plate Tectonics was founded in the 1950's the theory was first proposed by scientist Alfred Wegener in 1912. Wegener didn't have an explanation for how continents could move around the planet, but researchers do now because, one all the continents fit together like a puzzle, and two Fossil Evidence, the same fossils and species of animals found near the coastlines.
