load





Sediment carried along by ice, a river or the sea. Ice-sheets and large glaciers can carry a greater load than a thin glacier, so that they dump larger amounts of till when the ice melts. The load carried by a river depends on the type and amount of material available and the speed of the current. It may be in a solution or suspension, or be rolled along the river bed. A stream or slow-moving river can normally transport only mud and sand, whereas a fast-moving torrent can shift large boulders.
