Continental Drift + Tectonic Plates

Front

What is Continental Drift?

Back

The theory that continents have moved over geological time and were once joined together in a single landmass.

Front

What are tectonic plates?

Back

Large sections of the Earth's lithosphere that move and interact with each other.

Front

What type of boundary is formed when two tectonic plates move apart?

Back

Divergent boundary.

Front

What is subduction?

Back

The process where one tectonic plate slides under another and is forced into the mantle.

Front

What is the main force that drives the movement of tectonic plates?

Back

Convection currents in the mantle.

Front

Who is known for proposing the Continental Drift Theory?

Back

Alfred Wegener.

Front

What happens at a convergent boundary?

Back

Two tectonic plates collide, which can lead to mountain formation or subduction.

Front

What is seafloor spreading?

Back

The process by which new oceanic crust is created at divergent boundaries.

Front

What is a transform boundary?

Back

A boundary where two tectonic plates slide past each other horizontally.

Front

What geological features are commonly found at divergent boundaries?

Back

Mid-ocean ridges and rift valleys.
