The Plate Tectonics Theory

The Plate Tectonic Theory, which encompasses and supersedes the Continental Drift Theory, became
increasingly accepted from the 1960s onwards. With improvements in scientific techniques, more convincing
evidences were proposed and proven and this led to widespread acceptance.
The theory proposes that the Earth’s crust is comprised of a number of tectonic plates. It is the movement of
these plates that causes global changes in terms of the creation and destruction of landforms.
