Which landform may become more prominent when the base level of a river falls?
Answer and explanation
Correct answer: River terrace and incised meander
A fall in base level gives the river renewed potential energy and increases its ability to erode downward. The channel may cut into its former floodplain, leaving the abandoned surface as a river terrace; an existing meander can also become deeply incised. This combination is directly associated with rejuvenation. A coastal lagoon, loess plain, and stalactite have different coastal, wind-borne, and karst origins. Thus option B is correct.
