word bank
wetlands
buffer zones
estuary
non - point source pollutant
point source pollutant
runoff

1. natural areas with trees and shrubs that prevent erosion
2. pollutant that cannot be traced to its source
3. polluted rainwater that flows through watersheds
4. a body of water where saltwater and freshwater mix
5. pollutant that can easily be traced to its source
6. an area covered with water most or all of the year

give 2 examples of point source pollution.

Explanation:

1. Natural areas with trees and shrubs that prevent erosion - Buffer Zones. They act as a protective strip.
2. Pollutant that cannot be traced to its source - Non - Point Source Pollution. It comes from diffuse sources.
3. Polluted rainwater that flows through watersheds - Runoff. Rainwater picks up pollutants as it moves.
4. A body of water where saltwater and freshwater mix - Estuary. It is a transition zone between river and ocean.
5. Pollutant that can easily be traced to its source - Point Source Pollution. Has a distinct origin.
6. An area covered with water most or all of the year - Wetlands. Characterized by water - saturation.

Answer:

1. Buffer Zones
2. Non - Point Source Pollution
3. Runoff
4. Estuary
