• nutrient loading

• eutrophication

• upwelling

• Streams and Rivers

• Underground aquifers

Which are important characteristics of estuaries. (Check all the apply)

• Estuaries are areas where freshwater and salt water mix

• Estuaries have low diversity because many organisms cannot survive in the salty environment.

• Estuaries have a great amount of biodiversity

• Estuaries occur at the mouth of rivers

Which is a concern about unused, dissolved nitrates entering rivers and water supplies?

• Nitrates will reduce algae growth

• It will cause an overpopulation of fish

• It results in an increase in DO in water

• Nitrates will speed up the eutrophication process
