How does stream competence change proceeding downstream from headwaters towards mouth? A) Stream competence stays constant proceeding downstream from headwaters towards mouth B) Stream competence decreases proceeding downstream from headwaters towards mouth C) Stream competence increases proceeding downstream from headwaters towards mouth

B) Stream competence decreases proceeding downstream from headwaters towards mouth

Explanation:

Stream competence

It is the measure of the maximum size of the particles a stream can transport.

he particles are composed of small rocks, sand, clay, boulders.

These particles form the bed load of stream.

The larger size particles that a stream can transport always decreases proceeding downstream from headwaters towards mouth.
