3. Plates move  Plates are what move  They move what is on top of them  Crust is on top of the plates  Continental Crust- The crust that makes up continents/land  Oceanic Crust- The crust that makes up the oceans

4. Divergent Boundary  Plates move apart  Most are found in the ocean  Mid-ocean ridges are found where this happens  In the ocean they move apart and riff valleys form  This is how continents split apart  New crust is formed

5. Process  1. Hot material rises from the mantle  2. The heat causes the crust to bulge upward  3. The crust cracks, and a riff valley is formed  4. Magma rises, the continent splits apart

6. Transform Boundaries  Plates move past each other in opposite directions  Crust is not formed or destroyed  Occur mostly at the sea floor but can form on land too  San Andreas Fault

7. Convergent Boundary  Plates push together  3 different types  Continental-continental collision  Oceanic-oceanic collision  Oceanic- continental collision  Crust is destroyed or folded

8. Continental- Continental Collisions  Two continental plates collide  Each plate is the same density  No plates can sink, so it has to collide  Mountains are made when the two plates run into one another  EX: Rocky Mts.

9. Oceanic- Continental Collision  An piece of oceanic crust runs into a piece of continental crust  Oceanic crust sinks  Deep-ocean trenches  Costal mountains  EX: Andes Mts.

10. Oceanic-Oceanic Collision  2 plates run into one another  The older plate will sink under the newer plate  Subduction- When one plate sinks beneath another  The plate moves into earth, and melts  Forms  Deep ocean trenches- deep canyons on the ocean floor  Island arcs- volcanic islands  EX: Hawaii

11. Hot Spot  Heated rock rise in plumes, are thin columns from the mantle  The magma eventually hardens  The magma could have risen so high that it peaks out of the water  More islands will form in an arc, this shows how the plate is moving  EX: Hawaii
