• away from the axis

• on the top

• near the axis

• randomly distributed throughout

• normal

• graben

• thrust

• detachment

Shear stress applied to crustal rocks results in what kind of strain?

• tearing (strike-slip faulting)

• shortening and thickening

• shortening and thinning

• change in volume

• expansional

What are geologic cross sections designed to show?

• places most likely to experience earthquake damage

• subsurface structural interpretations based on surface and subsurface measurements

Increasing rock strength results in what type of strain?

• ductile

• elastic

• expansion

• brittle

• shear

Geologists define geologic formations as:

• the process of creating a rock

• a transgressive overlap

• recognizable mappable rock units

• a nice shaped identifiable rock feature

• the process of lithification

What is the difference between a joint and a fault?

• joint is a local bar frequented by geologists after mapping faults

• A fault is a fracture with movement; a joint is a fracture with no movement

• A fault results from tension; a joint results from compression

• A joint is a fracture with movement; a fault is a fracture with no movement

• A fault is caused by brittle deformation; a joint is caused by ductile deformation

Where on earth are strike-slip faults most common?

• the Wasatch Mountains of Utah

• the San Andreas Fault in California

• the North Anatolian Fault in Turkey

• the Alpine Fault in New Zealand

A notable geographical feature in Southern California is:

• The Grand Canyon

• Death Valley

• Mount Rushmore

• Niagara Falls

Fracture zones are typically found in relation to midocean ridges.

• Parallel to midocean ridges

• Perpendicular to midocean ridges

• Above midocean ridges

• Below midocean ridges
