2.  Rock Strata  These are rock layers under the surface.  They are normally flat (horizontal) when deposited.  Fold  Fault  Stratigrapher  Geologist that studies rock layers.  Rebound theory

3.  Flat - aka Horizontal

4.  Sometimes rock strata is squeezed and “folded”  A fold is when the strata is bent.

7.  How does flat strata become folded?  Compressional forces bend the strata.  Like paper would respond if you push the sides together

8.  Large scale folding

9.  What causes strata to fault or break?  Fault is when the strata breaks from outside forces.

11.  Think of a rubber band.  If I hold it out it will be flat.  But if I add weight it will dip down  But when I take the weight off it goes back.  The Earth does the same!

12.  Strike  The strike is a line the shows the directions on the surface of the fault.  Dip  The angle the plane goes into the ground.

13.  1.)Normal2.)Reverse (thrust)3.)Strike Slip  Faults are caused from forces within the Earth pushing or pulling rock strata.

14.  Head Wall  Foot Wall  Normal Fault  Head wall moves down  Reverse Fault  Head wall moves up ? ?
