Question

question 4
what did the cotton balls represent in our watershed model?
○ rock that is part of the watershed
○ vegetation on the watershed
○ snowpack on the watershed
○ pollution on the watershed

Explanation:

Watershed models often use materials to simulate natural components. Cotton balls, with their white, fluffy appearance, are commonly used to represent snowpack in such models, as snowpack shares similar visual and textural characteristics (light, soft, and white) in a simplified demonstration.

Answer:

Snowpack on the watershed
