Question

Quizplus · Accepted Answer

A fold that has an arch shape due to plastic deformation is called an anticline. This type of fold results from compression forces acting on rock beds, causing them to bend and fold upward. The opposite of an anticline is a syncline, which is a downward-arching fold caused by compression forces pushing rock beds downward. A plunging fold refers to a fold where the axis of the fold is not horizontal but rather dips at an angle. An isoclinal fold refers to a fold where the limbs of the fold are parallel to each other, creating an elongated and cylindrical shape.
