In what way are point source pollution and non-point source pollution different?
The contents of the pollution differ
If the source is industrial or residential

A local creek was being polluted. It was determined that the pollution was coming from a leak in an underground storage tank at a local carpet mill. What type of pollution is this?
point source pollution
non-point source pollution
thermal pollution
sediment pollution
Ecologist studying Lake Lanier discover it has high levels of nutrients such as nitrogen and phosphorus in the water. They determine the nutrients are common in fertilizers and are in runoff from local neighborhoods around the lake. This is an example of which type of pollution?
point source pollution
non-point source pollution
thermal pollution
bacterial pollution
What happens when excessive amounts of phosphates get into our lakes and ponds?
they cause a reaction that increases the temperature of the water
phosphates clean the water making the water perfectly clear
phosphates kill algae which make up a major part of the aquatic ecosystem
phosphates cause eutrophication to occur causing everything in the lake to eventually die
What is the main effect of artificial eutrophication?
a lack of overall nutrients in the water makes it uninhabitable for organisms
excess nutrients in the water causes algal blooms that consume all of the oxygen causing everything to die
a lack of light in the water causes an accumulation of sediment and debris to occur
excess light in the water causes the amount of bacteria to increase leading to a large number of infections in the aquatic organisms
What type of pollution is occurring if a manufacturing plant releases high temperature water into a local river causing fish kills and other issues?
nutrient
bacterial
thermal
sediment
How does the accumulation of plastic in the ocean affect the marine organisms?
Turtles eat plastic bags thinking they are jellyfish and they die from internal blockage.
Plastic rings from six packs will get caught on birds' beaks and cause them to become strangled
Seals and other marine mammals get tangled in fishing lines and drown
All of the choices are correct
What causes the greatest amount of ocean pollution?
oil spills
litter tossed into the ocean from ships
ships dumping sludge into the ocean
trash from activities on land getting carried into the ocean
Which of the following is NOT a primary air pollutant?
Powerplants releasing nitrogen oxide
Vehicles releasing carbon monoxide
Nitrogen oxide and water vapor mixing to form acid rain
Household products releasing VOCs (volatile organic compounds)
Which of the following produces primary air pollutants?
a. Vehicles
b. Power plants
c. Refineries
d. All of the above
Manufacturing plants
Automobiles
Refineries
All of the other answers are correct
When smoke and fog mix in large urban areas, we typically call it
water pollution
smog
acid rain
ozone depletion
How are lichen connected to air pollution?
The more lichen that are in an area, the cleaner the air. They are an indicator of air pollution.
The fewer species of lichen present in an area, the cleaner the air. They are an indicator species of pollution.
Lichen adapts quickly when the environment changes, so they are not used as an indicator.
There is no correlation between lichen and air pollution.
What happens to sea turtles when lights are left on at night along the beach?
The light has no impact on the turtles.
The light causes the eggs to hatch at different times.
The light attracts the baby sea turtles so they move away from the ocean.
The light causes the turtles to be seen by predators.
As the human population grows, more sulfur and nitrogen dioxide are produced. What is one of the impacts of these pollutants on our environment?
They bind with water vapor and create ozone.
They bind with water vapor and produce acid precipitation.
They bind with oxygen causing a decrease in the oxygen level in our atmosphere.
They bind with the oxygen in aquatic ecosystems causing aquatic organisms to suffocate and die.
Which pH level is considered to be acid rain?
Greater than 7.0
Less than 7.0
Less than 5.0
Less than 3.0
According to the data on the right, where and when
did the largest impact of acid precipitation occur?
Seneca Lake 1993
Morehouse Lake 2002
Morehouse Lake 1996
Seneca Lake 2007
Which of the following is NOT an impact of acid rain?
Eggs that will not hatch in aquatic ecosystems
Reduction in the number of aquatic animals and plants
Lower water temperature
Release of aluminum in soil that damages plants
Why do multiple countries around the world have conflict over acid rain?
They measure acid rain differently.
The U.S. endorsed the Kyoto Protocol.
The pollution causing the acid rain may be produced in one country but fall as acid rain in another country
None of the above
Why is the ozone layer so important?
It protects earth from global cooling
It protects earth from harmful UV rays and solar radiation
It protects the earth from the greenhouse effect
It protects earth from abundance of carbon dioxide
What caused the hole in the ozone layer?
CFCs (chlorofluorocarbons) in farming
CFCs in nuclear energy production
CFCs from burning fossil fuels
CFCs from coolants and spray cans
What treaty was signed to reduce the amount of chlorofluorocarbons in the atmosphere?
Montreal protocol
Kyoto protocol
Treaty of Versailles
Clean Water Act
Based on recent research, what is the trend for the levels of CO2 in our atmosphere over the past 100 years?
CO2 has been rising
CO2 has been declining
CO2 has been staying the same
The data is inconclusive
Why are scientist concerned about the increase in CO2 levels?
CO2 is a greenhouse gas so it causes more heat to be radiated back to earth - increases earth's surface temperature
CO2 is a greenhouse gas so it causes more heat to be radiated into outer space
CO2 is damaging the ozone layer causing an increase in dangerous UV radiation
CO2 build up is causing less plants to exist on earth's surface
Which of the following does NOT release greenhouse gases into the atmosphere?
Use of solar energy
Burning fossil fuels
Use of tractors and other machines for farming
Large gas-powered industrial machines
What is global warming?
Sun going through our atmosphere and heats Earth; some heat escapes to space while some is absorbed to provide warmth.
the gradual increase in the average global temperature due to an increase in CO2
the gradual increase in the average global temperature due to an increase in radon
the gradual increase in the average global temperature due to VOCs
Scientists hypothesize that global warming is caused by
smog
dead zones
CFCs
fossil fuels
Global warming will NOT cause which of the following?
a. Increased frequency of major droughts
b. Increased frequency of major storms
c. Increased polar ice mass
d. Rising sea level
More major droughts
More major storms
More polar ice mass in the poles
Higher sea levels
Which of the following is NOT a reason for global warming?
Research shows an increase in CO2
Data shows a relationship between CO2 and global warming for over 40,000 years
Data shows glaciers and sea ice at the poles is melting
