Unit 5 Topic 2M Flashcard

Front

What type of boundary creates trenches and deep underwater canyons?

Back

Convergent Boundary, Subduction Zone

Front

At which type of boundary does subduction typically occur?

Back

Convergent Boundary

Front

Why are earthquakes common in California and Japan?

Back

Both areas are on the boundary of active plates; the motion of the plates causes earthquakes.

Front

What happens at a convergent boundary when both plates are continental?

Back

They crumple up and form mountains.

Front

What occurs at a convergent boundary when one plate is oceanic and the other is continental?

Back

Subduction occurs, leading to earthquakes and volcanoes.

Front

Describe a transform boundary.

Back

Two plates move past each other along the edges horizontally.

Front

What happens when plates at a transform boundary get stuck?

Back

They can cause earthquakes when they slip and release.

Front

What is a divergent boundary?

Back

A boundary where two tectonic plates move away from each other.

Front

What geological features are commonly formed at divergent boundaries?

Back

Mid-ocean ridges and rift valleys.

Front

What is the primary cause of earthquakes?

Back

The movement of tectonic plates along boundaries.
