Which of these statements best describes suspended load in flowing water? Substances that are completely dissolved in the water Materials that are dragged along the bottom of the riverbed All the sediments that are being moved by flowing water Small fragments of sediment that is kept suspended in the flowing water

## Step 1<br />The problem is asking us to identify the correct definition of suspended load in flowing water. The term "suspended load" refers to the portion of sediment that is carried by a stream or river without touching the ground. This sediment is typically small enough to be carried by the water flow.<br /><br />## Step 2<br />Let's analyze each option:<br />- Option A: "Substances that are completely dissolved in the water". This does not describe suspended load, as it refers to substances that are fully dissolved in the water, not suspended.<br />- Option B: "Materials that are dragged along the bottom of the riverbed". This describes bed load, not suspended load. Bed load refers to the sediment that is transported along the river bed.<br />- Option C: "All the sediments that are being moved by flowing water". This is a broad definition that includes all types of sediment transport, not just suspended load.<br />- Option D: "Small fragments of sediment that is kept suspended in the flowing water". This is the correct definition of suspended load. It refers to small fragments of sediment that are carried by the water flow without touching the ground.
