97%
Water underground is stored in ____________.
aquifers
reservoirs
wells

Which best describes the relationship between temperature and dissolved oxygen in a lake?
As temperature increases, dissolved oxygen increases.
As temperature increases, dissolved oxygen decreases.
A change in temperature has no affect on the dissolved oxygen of water.
As temperature decreases, dissolved oxygen decreases.
Which would be the most likely cause of large numbers of fish dying in a stream?
decreased carbon dioxide
low dissolved oxygen concentration
high levels of mercury
a lack of nitrogen
If a body of water has turbidity levels, what can most likely be concluded?
It is too hot to drink.
It has a low pH.
It contains lots of chemicals
It is unsafe to drink.
Which aspect of fertilizer pollution would have the greatest negative impact on an aquatic system?
Algal blooms deplete the oxygen and block the sunlight from penetrating a body of water.
Aquatic animals increase, adding producers to the food chain and feeding fish.
Why are estuaries important to our environment?
Estuaries filter pollutants
Estuaries provide nurseries for marine life
Estuaries act as home for many wildlife
All of the above
Which process would most likely increase the dissolved oxygen level in a freshwater lake?
algal bloom
lake turnover
photosynthesis
respiration
Which is the best example of a point source pollution?
runoff from fields
pesticides sprayed into the air
oil spill from a boat on the Atlantic Ocean
smoke from multiple industries in a large city
Which will most likely result if there is increased upwelling in a coastal area?
more aquatic life
less nutrients in the water
higher water temperatures
fewer nitrates
Which contributes most in supporting life on the deep ocean floor?
cold water temperatures
extreme water pressure
hydrothermal vents
lack of predators
Which is the main source of dissolved oxygen in the ocean?
underwater earthquakes
decay of living organisms
animals that live near the surface
plants and algae that live near the surface
Light does not reach the bottom of the ocean, yet certain species live there. Which best explains how species on the bottom of the ocean get energy to live?
Algae and bacteria produce energy through photosynthesis.
Hydrothermal vents produce energy through chemical reactions.
Dead plants and animals produce energy through decomposition.
Which factors can have the greatest effect on the health of a river system?
type of soil and salinity
nitrate levels and turbidity
human consumption and pH
natural disasters and tidal changes
Species living in the Intertidal Zone must be able to survive which changes?
Moisture
Temperature
Salinity
All of the above
What affects the density of water?
Salt
Temperature
The seasons of the year
Salt and Temperature
______ causes deep ocean currents
The Coriolis Effect
gravity
wind
density differences
Surface winds cause surface currents by
causing the Coriolis effect
transferring energy to ocean water
absorbing energy from ocean water
producing a greater gravitational pull
Which of the following is a step of wastewater treatment?
Aeration
Chlorination
Filtration
All of these
Freshwater can be found in all of these places EXCEPT:

Rivers
Aquifers are sources of
freshwater, which is used for drinking, bathing, and watering crops.
saltwater, which is pushed through turbines to make energy.
oil, which is drilled from the aquifer and used to power homes.
silica, which is used to make glass and paper products.
The movement of deep, cold, nutrient filled water to the surface of the ocean is..
Ocean Current
Upwelling
Deep Currents
Surface Currents
Pollution where the cause can be easily identified is:
Point Source Pollution
Non-Point Source Pollution
Pollution where the cause is too massive to be identified is called what?
Non-point source pollution
Which of the following is the best example of a source of Point Source Pollution?
Pet owners leaving waste on the ground.
