Blind Thrust - ANSWER-A thrust fault that does not reach the ground surface detachment fault - ANSWER-A low-angle normal fault associated with regional extension Dip-slip Fault - ANSWER-A fault in which the movement is parallel to the dip of the fault. (ex. normal, reverse, or listric fault) Fenster - ANSWER-A "window" into rocks underlying a thrust fault Footwall block - ANSWER-The block that underlies a non-vertical fault Ga - ANSWER-Giga-annum; one billion years GIS - ANSWER-Geographi...

What is the apparent dip of a bed? - ANSWER-Apparent dip of a bed or plane is the inclination of that bed or plane in a direction not perpendicular to strike. What is a fold line and how is it used? - ANSWER-The fold line is a hinge line along which a vertical cross section may be constructed and then flattened out to a horizontal or map view. It is used to represent the subsurface along any given line in a map view. It need not be perpendicular to strike. What is the angle and side relati...

Structural Geology - correct answer Deformation of earth materials Deformation - correct answer Change in shape and/or volume Distortion - correct answer Shape change=constant volume Dilation - correct answer Change in volume Stress - correct answer For...

What is a fold line and how is it used? - ANSWER-The fold line is a hinge line along which a vertical cross section may be constructed and then flattened out to a horizontal or map view. It is used to represent the subsurface along any given line in a map view. It need not be perpendicular to strike. What is the angle and side relationships for the sin equation? - ANSWER-sinα = opposite side/hypotenuse What is the angle and side relationships for the tanget equation? - ANSWER-tanα = oppo...

What is an earthquake? - correct answer An episode of ground shaking Causes of Earthquake - correct answer Slip on a FAULT (fracture on which sliding occurs) or formation of a new fault Movement of magma in a volcano Explosion of a volcano Giant Landslide Meteorite Impact Underground nuclear-bomb tests How Is Rock Deformed? - correct answer Earth...

GLG 101 Final Exam | questions and answers | 2023/24 Rock Cycle - Magma cools and solidifies creating igneous rocks. Igneous rocks are exposed at the surface and eroded away creating sedimentary rocks. Sedimentary rock deform under heat and pressure to form Metamorphic rocks. How we determine the relative ages of rocks - We place rocks in their proper sequence of formation. Which rock formed first,second, third, and so on. Rock Types - Igneous Sedimentary Metamorphic Igneous Rock...

Mineral - correct answer Naturally occurring, inorganic, crystalize structure, chemical formula Isotope - correct answer Unstable element, more neutrons than protons Ion - correct answer An atom which has lost or gained electrons Rock - correct answer Cohesive aggregate of one or more minerals Compound ...

ASBOG Geologic Map and Cross Questions with complete solution 2023/2024Allochthon - correct answer A fault block or rock mass moved from its place of origin Autochthon - correct answer A rock mass underlying a thrust fault that has not moved from its location of origin Blind Thrust - correct answer A thrust fault that dies out in the subsurface as it loses slip and stratigraphic seperation Detachment Fault - correct answer A low-angle normal fault associated with regional ex...
