What is the large area of land that drains all of its water to a river when the surface is saturated?
- A.
River basin
- B.
Watershed
- C.
Estuary
- D.
Aquifer
Correct Answer
A. River basinExplanation
Remember that the difference between river basin and watershed is that watersheds are smaller and they make up river basins. Estuaries are where the river meets the ocean. Aquifers are the rock layers that surround the groundwater.Rate this question:

A water strider is a type of insect that "walks" on the surface of water without getting its feet wet. What property of water is in this insect using to stay on the water's surface?
- A.
Specific heat
- B.
Adhesion
- C.
Cohesion
- D.
Adhesion and cohesion
Correct Answer
C. CohesionExplanation
Cohesion is water sticking to other water molecules. Since water "sticks" to water, at the surface the water molecules will come so close together that this will allow the insect to walk on water.Rate this question:

Which body of water does not directly contribute water vapor into the atmosphere
- A.
Aquifers
- B.
Rivers
- C.
Oceans
- D.
Lakes
Correct Answer
A. AquifersExplanation
Since aquifers are underground, the water can not evaporate into the atmosphere.Rate this question:

Which of the following is not a source of fresh water?
- A.
An estuary
- B.
An aquifer
- C.
A lake
- D.
An ice cap
Correct Answer
A. An estuaryExplanation
Since an estuary is made up of freshwater and salt water is mixed into it, the water would not be considered fresh.Rate this question:

Groundwater supplies are stored in
- A.
Watersheds
- B.
Lakes and rivers
- C.
River basins
- D.
Aquifers
Correct Answer
D. AquifersExplanation
Aquifers are the rock layers the surround the groundwater. As the water seeps through the aquifer, it is purified.Rate this question:

What type of marine ecosystem can include rivers, marshes, and swamps?
- A.
Ocean
- B.
Estuary
- C.
Marine
- D.

What is sonar technology used for?
- A.
Mapping the sea floor
- B.
Mapping the circulation in deep water
- C.
Measuring the speed of sound through water
- D.
Measuring the salinity of water
Correct Answer
A. Mapping the sea floorExplanation
The Sonar device sends a signal to the ocean floor and a scientists waits and times how long the signal takes to return to the ship. The longer it takes to come back, the deeper the ocean floor is.Rate this question:
-
- 8.
The process of upwelling occurs as a result of
- A.
Warm, less-dense water that floats to the surface
- B.
Cool, dense surface water that sinks and pushes deep water up
- C.
Surface waves that mix surface and deep water
- D.
Sunlight that warms deep water that rises to the surface
Correct Answer
B. Cool, dense surface water that sinks and pushes deep water upExplanation
Cool water is denser than warm water. Cool, dense water tends to sink toward the ocean floor. As surface water sinks, it is replaced by deep water. Deep water moves up towards the surface bringing nutrients with it.Rate this question:
-
- 9.
Which of the following does not contribute to the salinity of the ocean?
- A.
Volcanic eruptions
- B.
Photosynthesis
- C.
Evaporation
- D.
Weathering
Correct Answer
B. PhotosynthesisExplanation
Photosynthesis adds to the dissolved oxygenRate this question:

What area of the ocean extends from the intertidal zone to the pelagic zone?
- A.
Abyssal zone
- B.
Neritic zone
- C.
Shallow benthic zone
- D.
Deep benthic zone
Correct Answer
B. Neritic zoneExplanation
The neritic zone is the zone that follows the intertidal zone.Rate this question:

Anoxic conditions in water occur when
- A.
Oxygen levels are high, about 14 ppm
- B.
Oxygen levels are between 5-14 ppm
- C.
Oxygen levels are low, between 2-4 ppm
- D.
Oxygen levels are less than 1 ppm
Correct Answer
D. Oxygen levels are less than 1 ppmExplanation
Anoxic means very little oxygenRate this question:
-
- 12.
What happens when there is an excess of nutrients in water?
- A.
Anoxia occurs
- B.
Eutrophication occurs
- C.
Plant growth is reduced
- D.
Algae growth is reduced
Correct Answer
B. Eutrophication occursExplanation
Eutrophication is the overgrowth of plant life which is what happens when there is too much nutrients in the waterRate this question:

Which of the following statements about water quality is true?
- A.
Fast-flowing streams have low levels of dissolved oxygen
- B.
Water with high turbidity lowers the temp of the water
- C.
Cooler water contains more dissolved oxygen than warmer water
- D.
Water with a pH level of 10 or greater is optimal for all aquatic life
Correct Answer
C. Cooler water contains more dissolved oxygen than warmer waterExplanation
The hotter the water, the less DO you have. The cooler the water, the more DO you have.Rate this question:

Macroinvertebrates that thrive in polluted water are
- A.
Tolerant
- B.
Intolerant
- C.
Facultative
- D.
Infacultative
Correct Answer
A. TolerantExplanation
Since they can survive there, we call them tolerant, because they can tolerate the pollution. Tolerate means they can "put up with" the pollution without it killing them.Rate this question:

Which of the following types of water would contain the highest level of dissolved oxygen?
- A.
Warm water
- B.
Slow-moving, calm water
- C.
Fast moving ,choopy water
- D.
Water with a high amount of nitrates
Correct Answer
C. Fast moving ,choopy waterExplanation
Generally, faster moving water has a higher level of oxygen that slower-moving water. This is because the swift currents flow over rocks and other land surfaces making them better able to dissolve atmospheric oxygen.Rate this question:

Which of the following is an example of point source pollution?
- A.
Stormwater runoff in a city
- B.
Waste water released from sewage plant
- C.
Air pollution released from industry
- D.
Acid rain
Correct Answer
B. Waste water released from sewage plantExplanation
Since there is only going to be 1 sewage plant in a city, it can only be coming from one place. Anytime you see runoff, you know it is NPS. You can not trace the acid rain back.Rate this question:

What water treatment method uses the process of condensation to purify water?
- A.
Distillation
- B.
Reverse osmosis
- C.
Boiling
- D.
Filtering
Correct Answer
A. DistillationExplanation
Distillation is the process of boiling water to separate the salt from the water and then collecting the water and cooling the water back into liquid water. Reverse osmosis uses filters to separate contaminants from water.Rate this question:

Which of the following practices is not a good way to conserve water?
- A.
Take showers that last 5-10 minutes
- B.
Wash only full loads of laundry
- C.
Keep the water running while washing dishes
- D.
Turn the water off when brushing teeth
Correct Answer
C. Keep the water running while washing dishesExplanation
Keeping the water running while washing dishes is not a good way to conserve water. This practice leads to unnecessary water wastage as the water continues to flow even when it is not needed. To conserve water, it is recommended to turn off the tap while washing dishes and only turn it on when necessary.Rate this question:
