Question 1

Rocks strained beyond their elastic limit by compressional stresses will result in

Accepted Answer

Folding occurs when rocks are strained beyond their elastic limit by compressional stresses, causing them to bend and form folds rather than breaking.

Question 2

The answer of Rocks that exhibit the effects of plastic...

Question 3

Accepted Answer

The answer of Plastic deformation would most likely be associated...

Question 4

Monoclines are the result of

Accepted Answer

Monoclines are typically formed by deep subsurface faulting that does not reach the surface, causing the overlying strata to bend and create a step-like fold.

Question 5

Geologic structures found in mountain ranges formed by compression at convergent plate margins would likely include

Accepted Answer

Mountain ranges formed by compression at convergent plate margins often exhibit a variety of geologic structures due to the intense pressure and deformation associated with plate collision. This includes overturned and recumbent folds, plunging folds, and reverse faulting, all of which are mechanisms through which the Earth's crust can deform under such stress.

Question 6

County officials associated with emergency planning and management should be most concerned with

Accepted Answer

Faults are fractures in the Earth's crust where significant movement has occurred, often leading to earthquakes, which are a major concern for emergency planning and management.

Question 7

For a normal fault to occur, which of the following sets of conditions would have to be present?

Accepted Answer

Normal faults are caused by tensional stress, which pulls the crust apart, and they typically involve brittle fracture, where the rock breaks rather than deforms plastically.

Question 8

For a fold to occur, which of the following sets of conditions would have to be present?

Accepted Answer

Folds are typically formed under compressional stress conditions where the material undergoes plastic (permanent) deformation without fracturing. This allows the layers of rock or sediment to bend and form a fold structure.

Question 9

Oceanic-continental plate orogenesis can be recognized in the geological record by

Accepted Answer

Orogenesis involving oceanic and continental plates typically features an accretionary wedge containing ophiolites (A) and a landward belt of volcanoes and batholiths (B), both of which are key indicators of such geological processes.

Question 10

Accreted terranes identified on the west coast of North America have been accreted within the past

Accepted Answer

Accreted terranes on the west coast of North America have been added to the continent through the process of plate tectonics over the past 200 million years. This process involves the gradual addition of material from the oceanic plate to the edge of the continental plate as they collide and interact.

Question 11

Terranes are believed to have originated

Accepted Answer

Terranes are believed to have originated from great distances, including opposite hemispheres, due to tectonic plate movements and collisions.
