WebThe theory of plates tectonics is a model that explains how the Earth’s outer crust and the inner mantle interact. The theory saw its emergence in 1915 by Alfred Wegener, as he goes on to explain his theory of “Continental Drift”. The theory states that the Earth’s outer crust (the lithosphere) is divided into several large, moving plates.
