CHAPTER 11DEFORMATION OF
CRUSTName: __________________
Period: _______Date: ___________
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 _____________________________________.
__________________ 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
Rocks deformed without breaking is called ____________________
3 types of folding: a.___________________________: up
curved fold with oldest layer in the center of fold
__________________________: down curved fold with youngest layer in the center of fold.
__________________________: fold where both limbs remain horizontal.
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.
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.
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.
4 types of mountains: ___________________________: collision of
continents, rock layers are squeezed together. Plateaus are common in the formation of mountains. Example: Himalayas
___________________________: 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
___________________________: molten material erupts onto the surface and builds a structure. Example: Cascade
• ___________________________: internal forces inside the earth push rock layers upwards. Example: Adirondacks
