Front

What happens when two continental plates collide?

Back

Mountains are created.

Front

What type of plate boundary forms islands from magma?

Back

Convergent plate boundary.

Front

What causes the movement of tectonic plates?

Back

Convection currents in the Asthenosphere.

Front

What evidence supported Wegener's proposal of a supercontinent?

Back

Rock, fossil, and climate data.

Front

What type of boundary is the San Andreas Fault?

Back

Transform boundary.

Front

What are tectonic plates?

Back

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

Front

What is a divergent boundary?

Back

A boundary where two tectonic plates move apart, often creating new crust.

Front

What is a convergent boundary?

Back

A boundary where two tectonic plates collide, leading to mountain formation or subduction.

Front

What is a transform boundary?

Back

A boundary where two tectonic plates slide past each other, causing earthquakes.

Front

What is subduction?

Back

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