Divergent Boundary

Front

What is a divergent boundary?

Back

A boundary between two tectonic plates that are moving apart.

Front

What causes seafloor spreading?

Back

New crust forms at divergent boundaries, pushing old crust outwards.

Front

What geological feature is formed at a divergent boundary under continental crust?

Back

Rift Valley.

Front

What are rift valleys and mid-ocean ridges associated with?

Back

Divergent boundaries.

Front

Which geological event can ONLY happen at a divergent boundary?

Back

Rift Valley.

Front

What happens to tectonic plates at a divergent boundary?

Back

They move apart from each other.

Front

What is the result of seafloor spreading?

Back

The ocean floor expands as new crust is formed.

Front

What is the difference between a rift valley and a mid-ocean ridge?

Back

A rift valley forms on land, while a mid-ocean ridge forms underwater.

Front

What type of boundary is associated with volcanic activity?

Back

Divergent boundaries can lead to volcanic activity as magma rises to form new crust.

Front

What is the role of magma at divergent boundaries?

Back

Magma rises to fill the gap created by separating tectonic plates.
