Question

1 multiple choice 1 point which is true of watersheds? all watersheds are the same size, because they are divided by humans. all watersheds flow south, because gravity pulls things south. watersheds are determined by natural slopes and water will flow downhill. 2 multiple choice 1 point which is a human impact on watersheds? nutrient & soil runoff from farming chemical pollutants from factories putting dams on rivers to change their flow all of these are human impacts on watersheds

Explanation:

1. Watersheds are areas of land where all the water that falls within it drains to a common outlet. They vary in size and are determined by natural topography (slopes), and water flows downhill due to gravity.
2. Farming - related runoff, factory - produced chemical pollutants, and building dams on rivers are all human - induced changes that impact watersheds.

Answer:

1. Watersheds are determined by natural slopes and water will flow downhill.
2. All of these are human impacts on watersheds.
