Bolivia
Where can convergent boundaries be found?
100
They can cause earthquakes, tsunamis, mountains, but they can cause fertile soil, and fossil fuels.
What is the theory that plate tectonics can do?

Convergent Boundary
What type of boundary is it when crust destroyed?
200
Crust
What is another name for lithosphere?

What is the solid, iron layer that makes up a small amount of Earth's mass

inner core


200
Iceland
Where can divergent boundaries be found?
200
Plate tectonics are the plates under the earth that make up the earths surface, they move because of intense heat.
What is the theory of plate tectonics

Divergent Boundary
What type of boundary is it when new crust forms?
300
When an oceanic plate and continental plate collide.
What causes subduction to occur?

continental-continental, oceanic-oceanic, and oceanic-continental
What are the three types of convergent boundaries?
500
