Any stream may lengthen its valley by ________ and delta formation.

Which of the following is NOT a component of stream load?

Most of a stream's transported material is classified as bedload.

A(n) ________ stream flows over a landscape that has been lifted so slowly so that the stream is able to maintain its course (even through mountains).

The load carried by overland flow past a point is generally small in comparison to what a stream can transport past a point.
