NATURAL RESOURCES
What are our two sources of fresh, drinkable water?
RESERVOIRS(which are lakes that hold fresh
water, like Hemlock and Canadice
Lakes)
and GROUNDWATER (which taps into the water that
flows underground, filling your
well)
What is the difference between
Passive solar power and Active
solar power
PASSIVE: no effort. Windows let in heat, solar cover on pool
ACTIVE: solar cells convert sun's energy into an electrical current (calculators)
Describe three uses of plants
1. OXYGEN2. FOOD
3. MEDICINE4. CHEMICALS
5. BUILDING MATERIALS
Where does solar energy come from?
The SUN
What are the three kinds of fossil fuels?
1. COAL (black “rock-like”, mined)
2. PETROLEUM (liquid, oil)
3. NATURAL GAS(gas found in ground)
Draw a picture of strip cropping
Define Erosion
EROSION IS THE LOSS OF TOPSOIL
(water washes it away or wind blows it away)
Which gases make up our air? What are their
percentages?
78% NITROGEN20% OXYGEN
2% CARBON DIOXIDE
Describe two ways in which water can be
polluted.1. RAW SEWAGE (waste water from
homes)
2. PESTICIDES (chemicals that kill
insects)
3. PHOSPHATES & NITRATES (fertilizers)
4. THERMAL POLLUTION (releasing hot
water into the environment)
Name the atoms used in Nuclear Fission
Nuclear Fission splits URANIUM atoms.
What is the main source of all air pollution?
BURNING FOSSIL FUELS!BURNING FOSSIL FUELS!
Name the type of conservation
farming method where the
farmer plows across a slope,
instead of up and down the
slope? CONTOUR
FARMING
Name the three characteristics
that make something a
Hazardous Waste
1. FLAMMABLE (burns easily)2. TOXIC (poisonous)
3. REACTS DANGEROUSLY with other substances
Name three ways to conserve fresh water
1. Replant vegetation on barren slopes2. Desalination (take salt out of salt
water)3. Build dams to create reservoirs
4. Protect our watersheds5. Use cooling towers
6. Waste water treatment plants
How do cooling towers help protect our water
supply?
Cooling Towers cool water from industry before releasing it into the
environment.
What is formed when water vapor mixes with nitrogen and
sulfur oxides?
ACID RAIN!
Explain the differences between Nuclear fission and
Nuclear fusion
Nuclear Fission is the SPLITTING
of Uranium atoms (fission
division) (radioactive wastes!
And costly!)
Nuclear Fusion is the
COMBINING of Hydrogen atoms
(no wastes! Not a reality yet!)
What are phosphates and nitrates, and how do they harm water and aquatic
life?Phosphates and nitrates are fertilizers. They
increase the plant growth in a body of water
(algae bloom). When the plants die off in large
amounts, bacteria decay the dead plants
and use up the oxygen in the water.
Fish and other aquatic life die.
What is SMOG?
Smoke + fog
How long does it take for 1 cm of topsoil to form?
200-400 years!
Which type of water holds more oxygen, warm or
cold?
Cold water holds more oxygen.
Define Geothermal Energy
Geo = earthThermal = heat
Using the heat in the earth to boil water and create steam. The steam is
then used to turn a turbine to generate electricity.
Draw a picture of Terracing
What is the difference between renewable resources and non-renewable? Give an
example of each.Renewable resources can be replaced,
reproduce, or cycle: water, air, nitrogen, plants, & animals.
Non-renewable resources are limited. Once they are gone, they are gone!
Coal, oil, natural gas, soil
Describe how a farmer practices Crop Rotation. What does he do? Which
plants should he use?The farmer would plant different crops in his field over time. Every couple of
years, he needs to plant a Legume (beans, peas, alfalfa, clover). These plants will return nitrates to the soil.
How do you prevent overgrazing?
Grazing animals (cows, horses & sheep) are moved from pasture to pasture
throughout the year. This allows the grass to grow back and the soil to recover from too much grazing.
Define depletion
Depletion is the loss of nutrients from the soil. This happens from planting the same crop in a field for too many years,
flooding, poor farming practices, erosion, etc.
What is a watershed?
A watershed is the LAND area around a lake or river. Water runs off the land and into the body of water. (it “sheds”
water into the lake!)
Describe Strip Cropping
Strip Cropping is when a farmer will plant a low cover crop in between a
taller crop. The low cover crop holds the soil in place and prevents erosion.
Draw a picture of windbreaks
Why is raw sewage a problem to aquatic life?
Raw Sewage increases the amount of bacteria in the water. The bacteria
decompose the sewage and use up the Oxygen that is in the water. Aquatic
life, that depends on the Oxygen, then dies.
What is it called when electricity is produces
through moving water?
Hydroelectric Power. As water moves through a dam, the water turns a turbine, which in turn
generates an electrical current.
From which Fossil Fuel does Gasoline come from?
Gasoline is one of the many by products of petroleum (crude oil)
Define Transpiration
The process by which plants give off excess water
Through Evaporation
How does water become a vapor (gas)?
Through respiration and/or excretion
How do animals give off excess water to the
atmosphere?
Through Condensation
How do Clouds form?
Why is Conesus Lake important?
Fishing, boating, vacationing, brings money into the community, drinking
water for Avon & Geneseo, ecologically important to plants & animals.
Changing the sun's energy into electricity (using solar cells)
What is ACTIVE solar energy?
