Download CHAPTER 11 Deformation of Crust

Name: __________________
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
