In structural geology, a linear fold in which the strata dip toward the axial trace and the younger rock layers are exposed in the central core is known as a:

💡 Solution & Explanation

A syncline is a downward fold in rock strata where the limbs dip inward toward the axis and the youngest rock layers occupy the center. In contrast, an anticline features upward arching strata with older rock layers exposed in the core. Recognizing these structural geological formations is vital for petroleum exploration and civil engineering site assessments.
