Question 20 • DRHS GA-GSE Environmental Science
Farm activities can loosen or expose soil, allowing rain to carry sediment into nearby streams, lakes, or ponds. The sediment can accumulate in the water and harm aquatic habitats, so “sediment accumulation in a body of water near a farm” is the representative effect. Fertilizer runoff typically contributes to excess algal growth and lower oxygen levels, not increased oxygen levels.
