Earthquakes, Folds and Faults.

Earthquakes, Folds and Faults.

1. Explain the relationship between earthquakes and plate tectonics. When certain tectonic plates have specific boundaries (such as transform faults and such) this can create tension build up. When the pressure is released, the tectonic plates will shake.

Why do earthquakes occur at places NOT on plate boundaries? Because it's not actually happening at the fault- it happens at the epicenter (the point on the ground directly above the focus, or hypocenter.)

2. Create labeled diagrams of the major types of faults - normal, reverse, overthrust, transform. Be sure to label movement direction and forces acting on the blocks.

3. Describe the dangers associated with earthquakes. Earthquakes cause major structural damage, can initiate tsunamis and generate volcanoes, as well.

4. Diagram the major types of folds - anticline, syncline, dome, geosyncline.
