Question Answer
Using this form of energy does not directly release CO2 into the atmosphere… electricity
In the daylight hours, demand and cost for electricity compares to night time Higher demand and greater cost in the day light hours.
Car pooling, riding the bus or trains
Dressing for the weather
Eating lower on the food chain
Walking, biking, using the stairs

Habits that will conserve energy
True or false?
Uranium is a fossil fuel.
Uranium is not a fossil fuel.
Globally this is the most abundant fossil fuel resource Coal
Relate coal to solar energy Through photosynthesis, coal is trapped solar radiation.
global climate change
Ecosystem damage
Black lung disease
accidents at mines
dangers associated with coal
Which fuel resources is most commonly used? crude oil
potential for spills that damage marine ecosystems hazard unique to crude oil
President Clinton, in the 1990s, protected what natural resource? Arctic National Wildlife Refuge (ANWR)
Lack of energy storage
High initial costs
Low insolation (available sunlight)
Intermittent generation
Obstacles to fully adopting solar power generation
Does not contribute to acid rain
Low greenhouse emission
Hg and Pb not released into environment
Less mining impact compared to coal
Advantages of nuclear power
What's new in nuclear power generation? smaller, less expensive, simpler and safer power plants.
Water is composed of… two atoms of hydrogen and one atom of oxygen
A hydrogen atom in one molecule being attracted to an oxygen atom of another hydrogen bonding
Watershed area of land drained into a single river
Water table upper limit of unconfined, underground water reservoir
Groundwater water moving through permeable rock and sediment
Irrigation greatest use of fresh water
flood plain area around a river most likely to flood
More building constructed in flood plains nowadays compared to the past increases destructive effects of floods
removing too much groundwater can result in sinkholes forming
A cause of increased precipitation in some areas and a decrease in others future climate change
About how many people, worldwide, do not have access to safe drinking water? 1 billion
Where in the USA are water problems most severe? Southwest, Colorado river basin
Reservoir artificial lake for water storage
Desalinization major industry in Saudi Arabia
wash only full loads of laundry
don't run faucet while brushing teeth or shaving
reduce shower time to less than 10 min
ways to conserve water
Escherichia coli (E. coli) bacterium indicating fecal/sewage contamination of water
Erosion leads to sediment pollution
Turbidity (how cloudy the water is) decreases light penetration and lowers photosynthesis rate
Synthetic organic compound pollution can lead to adverse hormonal effects
Mercury and lead can result in mental impairment
Fecal coliform test on water tests for presence/absence of E. coli
HIV/AIDS not shown to be transmitted by contaminated food an water
Mercury (Hg) emissions produced by and linked to coal fired power plants
Thermal pollution lowers dissolved oxygen (DO) in water
Eutrophication Increased photosynthetic productivity
reduced biodiversity
caused by nutrient enrichment
reduces dissolved oxygen (DO )
Oligotrophic lakes have naturally occurring low levels of nutrients
Large of sewage in water increases biological oxygen demand (BOD) and thus reduces dissolved oxygen (DO)
Gulf of Mexico dead zone is area of hypoxia (reduction or absence of oxygen) caused by decomposition of algae
when pollution is discharged into the environment from a pipe point source pollution
How much water pollution is attributable to agriculture? about three-quarters (72%)
Identify a unique source of pollution in the Ganges River of India? ash from cremated human remains
Chlorination in water treatment disinfects/kills pathogenic organisms
Primary water treatment removes suspended particles
Secondary water treatment decomposes organic wastes via anaerobic organisms
the EPA has authority to monitor emission limits under what law? Clean Water Act (CWA)
Resource Conservation and Recovery Act (RECRA) prevents groundwater contamination by … regulating the storage and disposal of hazardous wastes
