99 points will give brainliest me what is the general shape of a stream channel? how is a stream channel affected by movement of rock material through the stream?

The shape of a stream channel is usually flowing you could say. They constantly adjust to changes in stream flow

The channel is affected by the movement of rock material. The stream flows down a slope along a defined path. Streams may vary in width from centimeters to kilometers

Streams and Drainage Systems. A stream is a body of water that carries rock particles and dissolved ions and flows down slope along a clearly defined path, called a channel.
