The channel will start to migrate downstream more quickly when tectonic uplift occurs in an area's headwater zone. Here option C is the correct answer.
Tributaries join the river as it travels downstream, increasing the amount of water, velocity, and consequently the erosive strength. As it moves downstream, this permits it to cut a deeper channel. Less vertical erosion occurs as the channel widens and the gradient softens downstream.
Downstream, a stream's velocity often rises. Gravity, the absence of bed roughness, and an increase in the volume of water from the entrance of tributaries all contribute to enhance velocity as the gradient (slope) of the stream normally lowers.
