In steep bedrock channels, what features are typically developed?

In steep bedrock channels, the formation of pools and steps is a characteristic feature that results from the dynamic interaction of flowing water and the geological substrate. The channel's steep gradient means that water flows rapidly, which can lead to erosive processes that carve out deeper sections, creating pools. These pools are interspersed with shallower areas or steps, which act as natural cascades and are typically formed by the underlying hard bedrock resisting erosion.

This process is influenced by factors such as the rock type, the flow velocity, and the sediment load of the water. As water encounters variations in the bedrock, it can erode softer sections more readily, leading to the development of deep pools, while harder sections create ledges or steps. The alternating patterns of pools and steps contribute to the complexity of the channel morphology in steep environments, which is distinct from features found in more gentle, alluvial settings.

Other options refer to features typically associated with different landscape forms or geological processes. Caves and arches, for instance, are often formed in limestone environments through long-term chemical weathering and are not a primary feature in bedrock channels. Alluvial plains and delta formations are associated with sediment transport and deposition in river systems where flow energy decreases, leading to
