Question

If tectonic uplift occurs in the headlands portion of a river, what will likely happen to the rates of erosion there?

Multiple choice question.
a) The rates of erosion will decrease.
b) The rates of erosion will remain roughly steady.
c) The rates of erosion will increase.

Answer 1

Tectonic uplift in the headlands portion of a river will likely increase the rates of erosion there.

Step-by-step explanation:

When tectonic uplift occurs in the headlands portion of a river, the rates of erosion there are likely to increase. Tectonic uplift results in an increase in the elevation of the land, leading to steeper slopes. As a result, the river's flow becomes faster, which in turn increases the erosive power of the water. The increased erosion is evident in the formation of deep valleys and steep cliffs in mountainous regions.
