It is possible for the ____________ to return to its original _________ if the ______________ (stress) is applied and removed slowly. c.

When the ___________ passes the limits of the rock, the rock can be __________________ permanently and may ___________. 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.
