In cross section a structural basin looks like a ______.
A) dome
B) normal fault
C) anticline
D) bowl
E) reverse fault

Question

Quizplus · Accepted Answer

A structural basin is a type of geological structure formed by subsidence of the Earth's crust. In cross section, it appears as a bowl-shaped depression, hence choice D, "bowl," is the correct answer. A dome, choice A, is the opposite of a basin, in which the rock layers are folded upwards into a large, rounded structure. A normal fault, choice B, occurs when two blocks of rock move away from each other, creating a steeply inclined fault plane. An anticline, choice C, is a type of fold in which rock layers are bent upwards into an arch-like shape. A reverse fault, choice E, is a type of fault in which the hanging wall moves up and over the footwall, usually due to compression.
