Plate movement review

Front

What is a divergent plate boundary?

Back

A divergent plate boundary is where two tectonic plates move away from each other, often creating new crust as magma rises to the surface.

Front

What happens at a convergent plate boundary?

Back

At a convergent plate boundary, two tectonic plates move toward each other, which can lead to subduction or mountain formation.

Front

What is the least dense type of crust?

Back

Continental crust is the least dense type of crust compared to oceanic crust.

Front

What is created when oceanic and continental crust collide?

Back

A subduction zone is created when oceanic and continental crust move toward each other.

Front

Who proposed the theory of continental drift?

Back

Alfred Wegener proposed the theory of continental drift.

Front

What geological feature is formed when two continental plates move away from each other?

Back

A rift valley is formed when two continental plates move away from each other.

Front

What is a mid-ocean ridge?

Back

A mid-ocean ridge is an underwater mountain range formed by divergent tectonic plates.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate moves under another and sinks into the mantle.

Front

What is the difference between oceanic and continental crust?

Back

Oceanic crust is denser and thinner than continental crust, which is thicker and less dense.

Front

What is a transform plate boundary?

Back

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