How does the agricultural activity most likely affect the surface water of the area?

• Excess crop fertilizer is carried by runoff into the river, causing excess growth of water plants.

• Excess crop material accumulates on the riverbanks, slowing the movement of the river water.

• Crops reduce erosion, increasing the amount of soil entering the river.

• Crops absorb pure water from soil, causing the remaining water to contain more salt.
