1. Name: __________________ Period: _______ Date: ___________

2.  The bending, tilting, and breaking of the earth’s crust is _______________________.  The major cause is ___________________________.  The balancing of weight acting on the crust and the crust acting on the weight is called ___________________________. The up and down movement of the crust to balance are called _____________________________________.

4.   __________________ is the amount of force per unit area that is placed on a given material.  __________________ is the change in shape or volume of rocks.   Three types of stress:  ______________________: squeezing together.  ______________________: pulling apart.  ______________________: moving horizontal opposite directions

5.  Rocks deformed without breaking is called ____________________  3 types of folding:  a.___________________________: up curved fold with oldest layer in the center of fold

6.  __________________________: down curved fold with youngest layer in the center of fold.

7.  __________________________: fold where both limbs remain horizontal.

8.  When rocks break and do not move a _______________________.  When rocks move on the break its called a ___________________  The _____________________ is the surface of the fault where any motion occurs. ________________________ moves above the fault plane. ________________________ moves below the fault plane.

9.  Three types of faults  _____________________: hanging wall moves downward relative to footwall; occurs along divergent boundaries; tension is the force.  _____________________: hanging wall moves up relative to footwall; compression is the force. Occurs at convergent/collision boundaries.  Special type of fault, _____________________, has a low angle or nearly horizontal fault plane.  _____________________: rock on either side of fault plane slides horizontally; occurs at transform boundaries best known: San Andreas Fault.

10.  A __________________________ is a group of adjacent mountains with the same general shape and structure.  ____________________________ is a group of adjacent ranges.  ____________________________ a system of mountains that circum navigate the earth.

11.  4 types of mountains:  ___________________________: collision of continents, rock layers are squeezed together. Plateaus are common in the formation of mountains. Example: Himalayas

12.  ___________________________: earth’s crust has been extended and broken into large blocks; blocks are shifted by movement from the surrounding crust. ______________________ (long-narrow valleys between the blocks) occur. Example: Sierra Nevada

13.  ___________________________: molten material erupts onto the surface and builds a structure. Example: Cascade

14. ___________________________: internal forces inside the earth push rock layers upwards. Example: Adirondacks
