Failure to demand enough appropriate activity from the vocal mechanism. Deformation. Whether a material bends or breaks depends on . h. ow much stress is applied to the material.. Deformation. Process by which the shape of a rock changes because of stress.. Objectives:. Describe. What is a Fold?. A fold is a bent rock layer or series of layers that were originally horizontal and subsequently deformed.. Due to compression forces.. They are most visible in rocks that have layers.. and Folds. The illustration shows an east-west cross section between the Allegheny Structural Front and North Fork Mountain. The topographic feature called Germany Valley sits atop the geologic structure called the Wills Mountain Anticline. Westward directed compressive forces associated with the .

But when stresses act on hard, brittle rocks, they fracture or break the rocks. . A . fault is a type of fracture along which there has been relative movement displacing the wall rocks on either side of the fault.. During: Fault notes. After: Exit slip 4 questions. Day 1: Faults.

Diagnosis is the problem of trying to find what is wrong with some system based on knowledge about the design/structure of the system, possible malfunctions that can occur in the system and observations made of the behavior of the system..
