1. What is an orogeny A period of deformation, regional metamorphism, ig-
neous activity, and regional uplift and mountain building.
2. What is stress applied force per unit area.
3. What is strain change in shape and, or volume in response to stress or
pressure.
4. What is elastic deformation strain that is proportional to applied stress, and the de-
formation is recoverable
5. What is plastic deformation strain that is not proportional to applied stress, and the
deformation is not recoverable
6. What is brittle deformation, and a type of permanent deformation in which rocks fracture
what conditions are needed for it or break and in some cases experience faulting or relative
movement along the zones of breakage/fracture. shallow
depths, low P-T conditions
7. What is elastic limit The maximum stress that substance can withstand and
still show elastic behavior
8. 4 factors that determine rock de- Pressure-Temperature, physical strength, time, and rate
formation
9. 2 major types of stress directional and standing
10. What is compressional stress Stress that pushes together on a rock, which tends to
shorten it and may also reduce its volume. Folding,
thrust, and reverse faults.
11. what is tensional stress Stress that pulls a rock apart or extends it, which tends
to increase its length and may also increase its volume.

12. what is shear stress Stress that causes a rock to break along an infinite num-
ber of parallel planes and slide along those planes. strike
slip faults
13. what is a fault a fracture along which there has been significant dis-
placement
14. what is a joint is a fracture along which there has been little or no
displacement.
15. what type of evidence in the field offset, repeating, and/or missing beds, fault gouge,
suggest that faulting has occurred shear zones, fault breccias ,and slickensides
at some time in the past
16. what is an uncomformity is a buried surface of erosion or non-deposition, which
represents a break in the rock Record.
17. 3 factors that relate to the impor- Oil and Natural gases, Faults, joints, and fractures, and
tance of geologic structures unconformities
18. What percentage of the USA to- 51%
tal drinking water is supplied by
Groundwater?
19. What is the Hydrologic Cycle The Hydrologic Cycle is the circulation of water from the
Earth's surface to its atmosphere and back again.
20. Source energy for the hydro-logic Solar energy
cycle is

process by which water seeps into
the soil, regolith, or rock
