Question

Quizplus · Accepted Answer

When an area experiences tectonic uplift in its headwater region, the channel will begin to erode downward at a faster rate, as the uplift creates steeper slopes and a greater vertical drop for the water to flow through. This can lead to increased erosion of the channel bed and banks, as well as the formation of rapids and waterfalls. Choice A is incorrect because if the stream is eroding faster, it is likely to transport more of its load rather than deposit it. Choice B is incorrect because increased turbulence is often associated with more rapid flow and greater erosion. Choice D is incorrect because aggradation typically occurs when a stream is carrying more sediment than it can transport and begins to deposit it on the floodplain or in the channel. Choice E is incorrect because braided streams typically form in areas with high sediment loads and dynamic changes in water flow, not necessarily in response to tectonic uplift alone.
