Plate Motion Chapter 2 Flashcard

Front

What type of plate boundary has the plates moving away from each other?

Back

Divergent Boundary

Front

What type of plate boundary occurs when two plates move towards each other?

Back

Convergent Boundary

Front

What is the layer of soft, solid rock underneath Earth's plates called?

Back

Mantle

Front

What geological features are commonly associated with divergent boundaries?

Back

Mid-ocean ridges, earthquakes, and volcanic activity.

Front

What happens at a convergent boundary?

Back

Plates collide, which can cause mountains to form or one plate to be forced under another.

Front

What is a transform boundary?

Back

A plate boundary where two plates slide past each other horizontally.

Front

What is the significance of the mantle in Earth's structure?

Back

It is the layer that provides the heat and pressure necessary for tectonic activity.

Front

What geological activity is most commonly associated with transform boundaries?

Back

Earthquakes.

Front

What is the difference between oceanic and continental plates?

Back

Oceanic plates are denser and thinner than continental plates.

Front

What is subduction?

Back

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