Plate Boundaries
Crust
Convection
Where on Earth?
100
What type of plate boundary is shown in the picture?
Convergent plate boundary
100
What happens when an oceanic plate meets (or converges with) another oceanic plate?
The oceanic plate that is more dense will subduct (go under) under the other plate and is pushed into the mantle.
100
Draw the convection currents that would be happening in this situation:

Where on Earth is there an example of a very young mountain range?
The Himalayas
200
What process is happening at this plate boundary?
Subduction
200
What happens when an oceanic plate collides with a continental plate?
Subduction occurs, with the denser oceanic plate sliding under the continental plate.
200
Draw the convection currents for these tectonic plates.

Where on Earth is there an example of an old mountain range?
The Appalachians
300
What type of plate boundary is shown in this picture?
Transform plate boundary
300
What happens when two continental plates collide with each other?
The plates fold into each other, creating mountains.
300
What process is responsible for the movement of tectonic plates?
Mantle Convection Currents!
Convection currents in the mantle!

Where on Earth is there an example of a super old (ancient) mountain range?
The Canadian Shield
400
What type of plate boundary is shown in the picture?
Divergent plate boundary

Where on Earth are there two divergent continental plates?

500
Name a feature that forms at a divergent plate boundary.
Mid-ocean ridge
Rift Valley

Where on Earth is there an example of a transform plate boundary?
