• Volcanoes

What is a transform boundary?

• Where plates collide

• Where plates subduct

• Where plates slip past each other

• Where plates move apart

What is created at a divergent boundary on land?

• Ocean trench

• Mountain range

• Rift valley

What happens at a convergent boundary?

• Plates move apart

• Plates come together

• Plates slip past each other

• Plates remain stationary

What is formed when an oceanic plate collides with a continental plate?

• Mountain
