1. Earth Science
Turn in “Locating an Earthquake” activity from Friday!

2. Faults

3. Fault- surface along which rocks break and slide past one another

4. Hanging wall-block above the fault plane
Foot wall- block below the fault plane

5. Fault Types Normal faults- occur at divergent boundaries
Reverse faults- occur at convergent boundaries
Strike-slip – occur at transform plate boundaries

6. Forces
Tension- the force (stress) that occurs when forces act to stretch an object.

7. Forces
Compression – the type of stress that occurs when an object is squeezed, such as when 2 tectonic plates collide.

8. Forces
Shearing – forces one part of a body in one direction, and another part of the body in the opposite direction, causes a material to twist

9. Fault Model Lab Answer analysis questions (on front table) after you build your model
