Question

A stream’s discharge _____.

Answer 1

increases between its source and mouth

Answer 2

A stream’s discharge increases between its source and mouth.

A stream’s discharge is the volume of water that flows through a stream or river per unit of time. A stream’s discharge may also contain dissolved chemicals and any suspended substances. A stream’s discharge can be calculated by using the measurements of the stream’s velocity (length of travel per second), its depth, and width. A stream’s discharge increases between its source and mouth because of its increased velocity in those areas.
