how did the lab activities help you answer the lesson question: what factors affect the power of a river to…

Brief Explanations:

The lab activities likely provided hands - on data and visual evidence related to river erosion factors. By observing variables like water flow speed, sediment load, and riverbed composition in the lab, one can draw conclusions about what affects a river's erosive power. For example, faster water flow might be seen to increase erosion, and a higher sediment load could either enhance or inhibit it depending on the situation.

Answer:

The lab activities provided empirical data and visual/physical evidence to identify factors such as water velocity, sediment content, and riverbed characteristics that affect a river's erosive power. Conclusions could include that higher water velocity and certain sediment - related conditions increase a river's power to cause erosion.
