Question

what is the geologic structure shown in this picture?
syncline
anticline
reverse fault
left lateral strike - slip fault
normal fault

Explanation:

An anticline is a type of fold that is an arch-like shape with the oldest rocks at its core. In the image, the rock layers are bent upwards in an arch - like structure, which is characteristic of an anticline. A syncline is a downward - curving fold (the opposite of an anticline). Faults (reverse, left - lateral strike - slip, normal) involve displacement of rock layers along a fracture plane, which is not clearly visible in the image as a primary feature. The main feature is the arch - like bending of rock layers.

Answer:

Anticline
