Question

A syncline is ____________.

a. a fold in which the strata dip away from the axis
b. a fold with only one limb
c. a fold in which the strata dip toward the axis
d. a fold characterized by recumbent limbs

Answer 1

A syncline is a fold in which the strata dip toward the axis, typically forming a U-shape with younger rocks at the center.

Step-by-step explanation:

A syncline is a type of geological fold, characterized by layers of rock that dip inward toward a central axis. Describing a syncline, the correct statement is: a syncline is c. a fold in which the strata dip toward the axis. In simpler terms, when looking at a cross-section of a syncline, you'll see the layers of rock forming a U-shape, with the youngest rocks typically located at the center and the oldest on the outside. This is the opposite of an anticline, where rock layers dip away from a central axis.
