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?

Responses
A Step ZStep Z
B Step YStep Y
C Step XStep X
D Step W

Answer 1

Without the specific details of the diagram or the descriptions of Steps Z, Y, X, and W, I can provide a general answer based on common knowledge of the water cycle.

Insecticides used on crops can enter water bodies primarily through runoff. When it rains, water can wash insecticides from farmland into rivers and streams, leading to their presence in those water bodies.

The step of the water cycle that is typically associated with this process is precipitation (rainfall) that leads to runoff into waterways. Therefore, if one of the steps is related to precipitation or runoff, that would likely be the one contributing to the presence of insecticides in the river.

If you can provide more context or descriptions of Steps Z, Y, X, and W, I can help you identify the correct answer more accurately.
