ASBOG FG EXAM REG REVIEW CH. 2
STRUCTURAL GEOLOGY QUESTIONS
AND ANSWERS WITH SOLUTIONS 2024
Accuracy - ANSWER How close a measurement conforms with a standard or accepted value.
Apparent Dip - ANSWER The inclination of a plane measured in a direction not perpendicular to strike.
Apparent Dip Direction - ANSWER The bearing of the vertical plane containing the apparent dip angle.
Attitude - ANSWER The orientation in space
Beta - ANSWER The angle between strike and the apparent dip direction.
Bearing - ANSWER The horizontal angle between a line and a specified coordinate direction, usually
north or south.
Depth - ANSWER The vertical distance from the ground surface downward to a feature of interest.
Dip - ANSWER The inclination of the line of greatest slope of an inclined plane, measured perpendicular
to strike.
Directed Line - ANSWER A line described by its bearing and plunge.
Fold Line - ANSWER A hinge line along which a vertical cross section may be constructed and then
flattened out to a horizontal or map view.
Inclination - ANSWER A general term for the vertical angle between the horizontal and a plane or line,
measured downward.
Outcrop Width - ANSWER The width of an outcrop, as measured on map view, perpendicular to strike.
