Is a Bed load most responsible for stream erosion

no, suspended load is responsible for the most stream erosion

10. Question:
Which load is responsible for the most stream erosion?

Your Answer:
Bed load CORRECT ANSWER
Suspended load INCORRECT
Dissolved load

If a stream's discharge decreases how does it affect the stream's capacity

The capacity of a stream is the maximum load it can carry. Capacity is directly related to a stream's discharge. The greater the volume of water in a stream is, the greater its capacity is for carrying sediment. So if a stream's discharge decreases, the stream's capacity also decreases.

Permeable rock layers or sediments that transmit groundwater freely are called

Aquifers transmit ground water freely.

Most streams carry the largest part of their load

In Suspension.
