In what ways does a stream transport its load?
There are three ways: Traction which is also known as Saltation, Suspension and Solution.
Larger particles such as sand, gravel and boulders are moved by these processes where the Hydraulic force of the river is largely responsible as it either pushes the particles or applies drag on them as it flows over top of them.
Silt and clay are moved by this process. Turbulence within the water helps to keep the particles off the bed of the river.
Weathering of rocks supplies the chemicals that make up the dissolved load. Chemicals are carried as individual ions in solution. When limestone is weathered calcium ions and carbonate ions are dissolved and will be part of the solution load which is transported by the flow of the river.
Stream erode their channels by abrasion, grinding, and by dissolving soluble material. Stream transport sediment in three ways. 1. in solution (dissolved load) 2. in suspension (suspended load) 3. scooting or rolling along the bottom (bed load) Hope that helps. Lot of people trolling this days... Please do not delete.
The competence of a stream shows the maximum single load i.e. individual large rock, that the stream can move. It ignores the rest of the load in the river. The capacity would include the rest of the finer load so it is the whole load of the stream (including the large rock) Thus capacity will always be more than competence.
A stream can bounce large pebbles and boulders, along the stream bed. These rocks are called bed load. A stream can carry sand in suspension. These materials, called suspended load, make the river look muddy. The dissolved load is material carried in a solution, which means that the material is dissolved in the water. Sodium and calcium are some of the materials in the dissolved load.

The two ways that materials can pass through the cell membrane are active transport and passive transport. In active transport the molecules cannot pass freely across the membrane and have to be carried across in ways that require energy. In passive transport the molecules can pass freely across the membrane in ways that do not take any energy.
