• Increases biodiversity immediately downstream

• Alters natural flow regimes

• Reduces evaporation rates

After a heavy rainfall, David notices that water from nearby farms is flowing into the local river. How does this agricultural runoff impact the surface water?

• It increases water clarity

• It decreases the amount of nutrients in water

• It leads to eutrophication

• It reduces the presence of harmful chemicals

Scarlett is studying the effects of ocean acidification on marine ecosystems for her science project. What impact does ocean acidification have on marine life?

• It enhances the growth of coral reefs

• It has no significant impact

• It harms shell-forming organisms

• It increases biodiversity

After a factory spill, scientists observed two types of impacts on the local fish population. Which of the following is a difference between short term and long term impacts?

• Short term occurs slowly over time while long term occurs quickly.

• Short term affects organisms immediately while long term affects organisms over subsequent generations.

• Short term causes physical changes to the DNA of an organism while long term affects the behavior of the organism.

• Short term can cause extinction while long term usually affects organisms for five years or less.
