Plate Tectonics REVIEW

Class, here is a copy of the chart that shows the 3 types of Plate boundaries and their effects. You can click on it to see it bigger. This will be on the test. Study it! The topics for the test are shown below the picture:

This is a link to the video I showed you in class that showed all the animations of the different types of boundaries. Just click on it and look at all the videos on the left-- The Geological Society- Animation Videos on Boundaries
Here's another link that shows you some animations of boundaries-- Exploring Earth- Visualization


These are some notes from class on the 3 boundaries:

- Convergent boundaries: 
a) When an ocean plate converges with a continental plate, the denser ocean plate slides under the continental plate = Volcanoes or Trench (SUBDUCTION ZONE)
b) When two ocean plates collide, the denser ocean plate slides under the other ocean plate = Volcanic islands or Trench                
(SUBDUCTION ZONE)
c) When two continental plates collide, they crumble up = Mountains

- Divergent boundaries: 
a) When two ocean plates move apart, this causes seafloor spreading = Mid-ocean ridges OR Ocean basins
b) When two continental plates move apart = Rift valleys (a low point)

- Transform boundaries: 
When two plates slide past each other = Earthquakes

This is more information on the sub-types of Convergent boundaries only. Click on the picture to see it bigger:

These are the topics on the Plate Tectonics test:
- Pangea
- Evidence supporting the theory of Pangea
- Continental drift
- Seafloor spreading
- The names of scientists who developed these theories
- 3 types of boundaries and their effects
- Convection currents (due to density differences)
- VOCABULARY: Lithosphere, Asthenosphere, Mid-ocean ridge, subduction zone, etc.

*You should also know this: Differences in density cause the hot, plastic-like rock to be forced up toward the surface, causing the plates to move.
