Increasing the amount of sediments and rocks in moving flood waters increases the density of the flow.

Question

BlackTom AI · Accepted Answer

Restating the question: Increasing the amount of sediments and rocks in moving flood waters increases the density of the flow.

Option context: The question is a true/false type. The implied options are True and False, though the provided data lists an answer of True and doesn't show explicit options.

Reasoning for the statement: When solid particles (sediments/rocks) are suspended in a fluid, they add mass without proportionally increasing the fluid’s volume, which raises the overall density of the mixture compared to pure water. In flood flows with higher sediment concentration, the mixture becomes denser due to the presence of these solid constituents.

Potential nuance: While density increases with more suspended solids, other properties of the flow (such as viscosity, momentum, and turbidity) also change. The main point for density is that the mass per unit volume is greater than that of clear water, so the flow is indeed denser when more sediments are present.

Why the alternative would be incorrect: If one claimed that adding sediments does not affect density, they would be overlooking the fundamental definition of density as mass per unit volume. In a suspension, the added solid mass directly contributes to a higher overall density. Any assertion that density decreases or remains unchanged would misinterpret the physical effect of suspended solids. Additionally, noting that density might plateau or be influenced by settling over time is advanced, but in moving flood waters with ongoing suspension, the instantaneous density is higher than that of clean water.
