What are the components of sediment load moved by a stream?

The correct answer highlights the three main components of sediment load that rivers and streams transport: Dissolved Load, Suspended Load, and Bed Load.

The Dissolved Load consists of material that is carried in solution, which means that minerals and nutrients have been dissolved in the water. This type of load is important for transporting nutrients necessary for aquatic life.

Suspended Load includes particles that are small enough to be carried within the water column. These particles can include silt and clay, and they remain suspended because the turbulence of the water keeps them aloft. This component is significant in determining water clarity and the overall health of aquatic ecosystems.

Bed Load refers to larger particles that move along the riverbed. These are typically sand, gravel, and cobbles that are rolled, slid, or bounced along the bottom. The bed load contributes to the shaping of riverbeds and can affect the stream's morphology.

The other options do not accurately reflect the established terminology used in sediment transport studies. The terms in the other choices do not describe the physical processes by which sediment is transported in streams. Thus, they lack the specificity and relevance needed to properly characterize sediment load in hydraulic environments.
