Which one of the following is not a fluvial landform?
Explanation
Fluvial landforms are features created by the erosional and depositional actions of running water or rivers. Erosional fluvial landforms include deep, steep-sided valleys such as gorges and canyons, which are formed through vertical downcutting and valley deepening [2]. Depositional fluvial features include braided channels (or braids), where a river splits into multiple narrower channels that diverge and rejoin around sediment bars [3]. In contrast, a cirque (often spelled 'cire' in some contexts or misspellings) is a glacial landform. It is described as an amphitheater-shaped, deep, long, and wide trough or basin cut into mountainsides by the movement of accumulated ice. While gorges, braids, and canyons are fundamentally linked to river processes, cirques are the most common erosional landforms in glaciated mountains.
