Plate Tectonics Check

Front

How do most mountains form?

Back

Most mountains form when continents collide and fold up on each other.

Front

What type of boundary created the Great Rift Valley in Africa and the Mid-Ocean Ridge?

Back

The Great Rift Valley in Africa and the Mid-Ocean Ridge were created by a divergent boundary.

Front

What forms when two continental plates converge?

Back

When two continental plates converge, mountains are formed.

Front

What are the two types of crust?

Back

The two types of crust are continental and oceanic.

Front

What happens at divergent boundaries?

Back

At divergent boundaries, new material is added to plates.

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates move towards each other, often causing mountains or trenches.

Front

What is a transform boundary?

Back

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

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and upper mantle.

Front

What is the asthenosphere?

Back

The asthenosphere is the semi-fluid layer beneath the lithosphere that allows tectonic plates to move.

Front

What is subduction?

Back

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