2. Folding
a. When ____________ responds to stress by becoming permanently
____________________ without breaking.
b. _________________ can be easily observed where the rocks are
______________________ inward and the layers of the rock move
into new positions _____________________ breaking. (___________
may appear, but the rock layers remain ________________.)
c. _____________ of folds can vary greatly.
i. Some rock ____________ can be found within a small
____________-size rock while others span of ______________
of miles and must be seen from __________.
d. There are __________ types of rock folding: ___________________,
__________________, & _____________________.
i. An _______________ fold is an _____-curved fold in which
the _______________ layer is in the ____________ of the fold.
1. Mountain ______________ are generally found along
________________.
ii. A _________________ fold is a ____________-curved fold in
which the ___________________ layer is in the center.
1. ________________ are generally found along synclines.
iii. A ____________________ fold is a fold in which both sections
remain ____________________.
3. Faulting & Fracturing
a. _______________ do not always respond to __________________ by
folding. Under certain conditions rocks will actually ______________
when stress is applied.
