Front

What is the process by which one tectonic plate is forced under another?

Back

Subduction

Front

What type of tectonic plates are colliding at convergent boundaries?

Back

2 oceanic plates, Oceanic and continental plate, or 2 continental plates.

Front

Why does the oceanic plate subduct under the continental plate?

Back

Because it is more dense.

Front

What causes Earth's tectonic plates to move?

Back

Convection currents in the mantle.

Front

Which crust is less dense: continental crust or oceanic crust?

Back

Front

Which crust is thicker: continental crust or oceanic crust?

Back

Continental crust is thicker than oceanic crust.

Front

What is the main characteristic of oceanic crust?

Back

It is primarily made of basalt and is denser than continental crust.

Front

What happens at a convergent boundary?

Back

Two tectonic plates collide, leading to subduction or mountain formation.

Front

What is the result of two continental plates colliding?

Back

Mountain ranges are formed.

Front

What is the term for the area where one plate is forced under another?
