Alfred Wegener, a German meteorologist and geophysicist, first proposed the Continental Drift Theory in 1912.

Wegener's theory was primarily supported by the fossil record, which showed that similar fossils were found on different continents that are now separated by oceans.

Wegener proposed that convection currents in the Earth's mantle were responsible for the movement of continents.

Pangea was a supercontinent that existed during the late Paleozoic and early Mesozoic eras, approximately 250 million years ago.

Continental collision is the process by which continents collide and merge together, forming larger landmasses.

The Himalayas were formed as a result of the collision between the Indian and Eurasian plates.

The Great Rift Valley is a rift valley that is forming as the African Plate splits apart.

Pangea Ultima is the name of the supercontinent that is predicted to form in the future as a result of continental drift.

Plate tectonics is the theory that explains the movement of Earth's tectonic plates.

A divergent boundary is the boundary between two tectonic plates that are moving apart.

A convergent boundary is the type of plate boundary that is responsible for the formation of deep ocean trenches.

A transform boundary is the boundary between two tectonic plates that are sliding past each other.

A convergent boundary is the type of plate boundary that is responsible for the formation of volcanoes.

Subduction is the process by which one tectonic plate moves beneath another.

A convergent boundary is the type of plate boundary that is responsible for the formation of earthquakes.
