When fertilizers enter surface water, they cause problems in 
the watershed by -

• increasing the amount of nutrients available to fish in lakes and streams.
• 
  clogging narrow streams and preventing water from flowing properly.
• raising the water level in nearby rivers to levels leading to flooding.
• causing rapid algal growth that decrease oxygen levels and choke aquatic life.

The illustration provided shows a river and four cities on that river. When the water from the river was sampled at location X, it was determined to be polluted with various chemicals. What would be the most likely source for this pollution?

• City 1 and City 2
• City 2 and City 3
• City 3 and City 4
• City 1 and City 4

Review the graph showing marine fishing rates.If the fishing rate in Asia continues to grow, what will most likely happen as a result?

• The fish population will continue to rise.

• A wide range in ocean temperatures will be seen worldwide.

• The U.S. human population will decline.

• The overfishing will cause an imbalance in marine ecosystems.

What is one way humans are trying to positively impact the ocean?

• Creating artificial reefs

• Transporting goods in ocean vessels

What do we depend on the ocean for?

• Food

• Oxygen

• Transportation

• All of the above

Some areas of an ocean are known as dead zones. These zones form when excess organic material decomposes. This increased decomposition uses up the oxygen from the water.

Which human activity is most affected by the increasing number of dead zones in the ocean?

• Offshore oil drilling, because water in dead zones is toxic

• Commercial fishing, because fish cannot survive without oxygen

• Commercial shipping, because dead zones change the course of ocean currents

• Sand mining, because oxygen is not available to form the sands on ocean beaches

• Over-fishing

• Artificial reefs

• Recycling
