Question

Quizplus · Accepted Answer

Tectonic uplift of the headwaters will increase the rate of downcutting of the stream, leading to the formation of stream terraces. A large increase in sediment load (A) may fill the stream channel and prevent terrace formation. A rise in sea level (C) will cause flooding and deposition on the floodplain rather than terrace formation. A decrease in rainfall (D) may decrease the amount of water in the stream, but it will not necessarily lead to terrace formation. Earthquake activity at the river mouth (E) may cause changes in the shape of the river mouth, but it will not necessarily lead to terrace formation.
