What is continental drift?
Continents are always maintaining their positions.
plates are colliding in the athenosphere
continents were once joined and continue to move over time
Continents are always stationary on a liquid core.

varies
Decreases
never changes
Increases
21
What are transform plate boundaries?
Plates that move apart
Plates that slide past each other
Plates that move together
Plates that don't move at all
22
Volcanoes are located at the point where the blue and purple plates meet. What is happening here to create volcanoes?
Plates are moving away from each other
plate are moving toward each other and colliding to push up
Plates are moving toward each other and one slides under the other
Plates are moving past each other
23
One way Scientists learned about the layers of the Earth is from:
The water cycle
Space technology
subduction zones
Seismic (earthquake) waves
24
Transform boundaries...
Never move.
move away from each other.
cause mountains due to the plates colliding/moving towards each other.
can cause an earthquake when they slide past each other.
25
What are convergent plate boundaries?
