Bedrock and sediment in a stream is most susceptible to erosion if it is
A)in slow-moving water in an eddy.
B)in a site that is sheltered from oncoming clasts.
C)located in a turbulent part of the river.
D)composed entirely of large clasts that affect stream flow.
E)All of these are correct.

Question

Quizplus · Accepted Answer

Sediment in a turbulent part of the river is most susceptible to erosion because the high velocity and turbulence of the water can more easily transport and move sediment. Slow-moving water in an eddy (A) is less likely to erode sediment, while a sheltered site (B) may protect sediment from oncoming clasts, reducing erosion. Sediment composed entirely of large clasts (D) can also affect stream flow but may not always be the most susceptible to erosion, as smaller sediment can still be easily moved by fast-flowing, turbulent water.
