Mountain streams and rivers typically are characterized by:

A) steep gradients and are confined by bedrock canyons
B) low gradients and unconfined channels
C) steep gradients and unconfined channels
D) low gradients and are confined by bedrock canyons

Steep Gradients

Areas of land with a sharp incline or slope, often leading to faster water flow and potential erosion.

Bedrock Canyons

Bedrock canyons are deep, narrow valleys with steep sides, carved into bedrock by the erosive action of flowing water over geological time periods.

Unconfined Channels

Natural river channels that are not constrained by man-made structures and are free to change course and flood.
