Air Pollution

Global Warming

100

What is the primary gas causing global warming?

Carbon Dioxide

200

What happens when greenhouse gas amounts increase

Global Warming (increase in Earth's temperature)

300

What are two causes of increased CO2 in the atmosphere?

1. Increased use of of fossil fuels 2. Fewer plants absorbing CO2

400

What are four effects of global warming?

1. Earth's temperature rising 2. Ice in the polar caps melt 3. Sea levels rising 4. Saltwater contaminating fresh water. 5. Weather patterns changing 6. Decrease in crop yields.

500

Why is the Greenhouse effect so pronounced on Venus?

There are no Plants to absorb the CO2.

Outdoor & IndoorAir Pollution

100

Which gas is the primary component of the atmosphere?

Nitrogen

200

What are two type of air pollution that is caused naturally?

1. Air Pollen 2. Volcanic eruptions 3. Forest Fires 4. Sand/dust storms. 5. Gases from decaying organisms.

300

When did air pollution problems begin?

Industrial revolution of 1800's

400

Why is air pollution considered a global problem?

Air pollution does not stay in one place, constantly moving from one country to another.

500

Describe the formation of ground level ozone

Nox + VOCs + sunlight ---> O3

Air Pollution and Human Health

100

What indoor air pollution is the deadliest (causes the most deaths?)

Cigarette smoke

200

List two diseases cigarette smoke cause?

1. cause lung cancer 2. cause emphysema

300

What are three sources of indoor air pollution effecting humans (must identify the source and human health impact for each)?

1. Cigarette smoke 2. Molds 3. Carbon Monoxide poisoning 4. Radon Gas

400

name one example of VOCs and describe human impact and prevention methods

formaldehyde headaches, respiratory tract irritation, eye irritation, skin rash improve ventilation or use formaldehyde free materials (substitute for safer materials)

500

describe the source or radon and prevention methods

Radon- naturally occurring radioactive gas from uranium prevention- cracks in the foundation of building must be sealed and proper ventilation system

Air Pollution and the Environment

100

What is the pH level of acid rain?

pH of 5.5 or lower.

200

What is "thermal inversion."

Smoke and fog (smog) trapped between warm & cool air layers.

300

What can be added to acidic soil or water to neutralize acidity.

Powdered lime (calcium carbonate) CaCO3

400

What are two affects of acid rain on plants?

1. leaching important minerals from the soil (soil depletion) 2. Prevents sprouting of seeds 3. May destroy entire forest.

500

What are two ways acid rain affect humans?

1. Destroys/damages monuments & statues. 2. Destroys/damages personal property such as car paint, corrodes car tires, corrodes steel on homes & cars, etc. 3. decrease in crop yield --> hunger

Ozone & CFC's

100

What does ozone in the atmosphere protect the earth from?

Ultraviolet (UV) rays of light

200

What the two types of ozone and which is good and bad? Must describe the formation of each

Ozone in atmosphere - good (naturally occurring) Ozone close to ground - bad (anthropogenic)

300

What are two sources of CFC's?

1. Freon in fridgerators. 2. Propellants in aerosol cans 3. Used in constructing styrofoam

400

What are three effects of too much exposure to UV light.

1. Sunburn 2. Blindness 3. Skin Cancer 4. Crop damage 5. Death/mutations to organisms.

500

describe the destruction of ozone layer caused by CFCs. you may use chemical equation to support your answer

CCl2F+ UV --> CCl2F +Cl free Cl +O3 --> ClO +O2 Free Cl can destroy up to 100,000 O3
