What can a river terrace indicate?
Answer and explanation
Correct answer: Renewed downcutting after an earlier flood plain
A river terrace is an abandoned former valley-floor or flood-plain level that now stands above the active channel. The governing process is renewed vertical erosion, often associated with river rejuvenation caused by uplift, falling base level, or increased discharge. Thus option D is correct. A terrace is not, by itself, evidence only of marine fossils, wind change, or limestone solution.
