What layer is the lithosphere found?
Crust
What causes fold mountains?
Two continental plates colliding
Where can a person touch two divergent tectonic plates at one time?

What is the theory of plate tectonics?
Theory that Earth's lithosphere is composed of "plates" that move as a result of convection currents
What type of boundary is it when new crust forms?
Divergent Boundary
What causes subduction to occur?
When a continental converges with another continental or an oceanic plate.
What boundary and plate movement forms folded mountains?
convergent-continental to continental
Where can transform boundaries be found? (HINT: in the USA)?
California
Where two plates slide against or past each other.
Transform boundary
What type of boundary is it when two plates slide past each other?
Transform Boundary
What causes plates to move?
Convection Currents
What are two mountains formed by convergent boundaries?

What are the three types of convergent boundaries?
continental-continental, oceanic-oceanic, and oceanic-continental
What are plate tectonics?
Broken parts of lithosphere that carry continents and oceans
How are the layers of the earth organized ?
Kinds of elements and density of elements.
