Below is a diagram of the water cycle. Local environmental scientists have collected evidence of the presence of multiple insecticides in the river. Insecticides are used on crops to help prevent crop damage from insects.

Question

Which step of the water cycle most likely contributes to the presence of insecticides in the river?

Answer 1

The step of the water cycle that most likely contributes to the presence of insecticides in the river is likely related to runoff. Insecticides used on crops can wash off into nearby water bodies when it rains or when irrigation occurs.

Without specific descriptions or labels for Steps Z, Y, X, and W, I can't directly identify which letter corresponds to this runoff process. However, if one of these steps involves precipitation, surface runoff, or another mechanism through which water from the ground (where insecticides might be applied) enters the river, that would be the most related to the presence of insecticides in the river.

Typically, a step indicating runoff or precipitation would be involved. If you can provide more specific information about what each step represents, I can help you determine the correct answer.
