Learner Express: Modules for Teaching and Learning
Standing by a mountain stream, Dr. Sherilyn Williams-Stroud, senior research scientist at Chevron-Texaco Energy Technology Company, explains how moving water can carry material from mountains to the sea.

Larger streams flow into rivers and, eventually, the sediment they bear is carried out to the sea. Run Time: 00:02:19
