Answer:
D. Lowering of the sea level.
Explanation:
- Stream incision is a cause and consequence of the increase in the river load carrying capacity and also its former floodplain if uplifted by the presence of mountain ranges and more discharge rates.
- As the streams channel drops the water in surrounding aquifers runs into the streams, thus lowering the water table a this modifies the flow pattern of the stream, and leads to large reductions of summer flows.
- The incision is thus a play of the river with its tools and speed of the river and the amount of discharge governs the flow patterns hense, this impacts the river way of cutting.
Classy and smooth is the answer
Weather is known over short periods of time and can be inaccurate, climate is figured out over long periods of time and effects a larger area
