Which folding type represents a local steepening in uniformly dipping strata?

A monocline represents a local steepening in uniformly dipping strata, which is why it is the correct choice. This geological structure occurs when there is a bend in otherwise horizontal or gently dipping layers of rock. As a result, the strata are steepened along the monocline, which can create a dramatic change in the dip of the layers without affecting the overall uniformity of the surrounding strata.

Anticlines and synclines, on the other hand, involve a folding structure where layers of rock are arching upward or downward, respectively, but do not specifically refer to a steepening of uniformly dipping rock layers. An anticline forms a peak, while a syncline forms a trough, both of which necessitate more significant folding of the strata as a whole rather than just a localized steepening.

Reverse folds, while involving an upward movement of rock layers, typically indicate a more complex interaction often associated with compressive forces and do not describe the scenario of a localized steepening in uniformly dipping layers. Thus, the characteristics of a monocline best fit the question's requirement.
