1. Divergent and Transform Plate Boundaries 10/7/15 7-3c pgs. 179-180 IN: What do you think happens when tectonic plates slide past one another?

2. These plates are moving around.  Which means that they: ◦ Collide  run into one another ◦ Divide  move away from one another ◦ Slide  slide past one another

3.  Hot material deep within the Earth rises while cooler material near the surface sinks. ◦ This is what causes tectonic plates to move around. Convection

4.  Collide  When two tectonic plates push into one another. Convergent Boundaries

5.  3 types: ◦ Continental/Continental ◦ Continental/Oceanic ◦ Oceanic/Oceanic

6. Continental/Continental  Forms mountains.

7. Continental/Continental  Forms mountains

8. Continental/Oceanic  Forms land volcanoes and trenches.

9. Mariana Trench -6.75 miles deep. -If Mount Everest, the highest mountain on Earth at 8,850 meters (29,040 ft), was set in the deepest part of the Mariana Trench, there would be 2,060 meters (6,760 ft) of water left above it.Mount Everest

10.  The region where oceanic plates sink down into the asthenosphere. ◦ Forms deep sea trenches. Subduction Zones

11. Oceanic/Oceanic  Forms ocean volcanoes and islands.

12.  Divide  When two tectonic plates move away from one another. Divergent Boundaries

14. Divergent Boundary  Sea-floor spreading ◦ continental/continental  Rift valley ◦ oceanic/oceanic  Mid-ocean ridges

17.  Slide  When two tectonic plates slide past each other horizontally. Transform Boundaries

18. Transform Boundary  Earthquakes!  San Andreas Fault in California

20. Tracking Motion  GPS satellites
