•
The burning of fossil fuels release CO2. When
greenhouse gases (CO2, CH4, NO2, H2O)
are struck by infrared radiation, the
molecules vibrate and emit the radiation at
a lower wavelength. These lower
wavelengths remain trapped in the
troposphere, trapping heat energy and
raising average global temperatures.
Strengthen this weak statement: “Fossil fuel use releases
carbon dioxide, which causes the greenhouse effect.”
9. The acronym BOD refers to
Biological Oxygen Demand
,
which is
the amount of dissolved
oxygen needed by aerobic
biological organisms (like
bacteria) in a body of water to
break down organic material
present.
10. The acronym GMO refers
to
genetically modified
organisms
, which is
any
organism whose genetic
material has been altered
using genetic engineering
techniques.
11. Perform the following calculation. Show all of
your work. If the grasses on a 100-hectare area of
grassland grow at an average rate of 1 cm/day,
the average volume of grass that is added to the
grassland each day is ____________ m

density of the grasses that grow in the grassland
averages 400 kg/m

12. Strengthen this weak statement:
“Protecting endangered species like the Giant
Panda costs too much and should be stopped.”
•
Biodiversity offers many benefits:
products like food, medicines, fuel. It
provides ecosystem services, and
each individual plays specific roles in
an ecosystem. More diverse
ecosystems are more stable and more
productive. The panda likely controls
bamboo populations and should be
preserved. The ecological benefits
outweigh the monetary cost.
13. Perform the following calculation. Show all of your work. A

solar array is installed on a house where the average
insolation is 6 kWh/m
2
/day if the average total electricity
output of the array is 1.2 kWh/hr, the efficiency of the array is
____________.
•
“insolation” = Amount of radiation that strikes a
given location over a given period of time
•
6 kwh
x 40m2 =
240kWh

14. Consider the graph on the right and explain what can be inferred from the
data it presents.
The more women are educated and
empowered, the fewer children they choose
to have, lowering Total Fertility Rate of a
country.

________________ National Park.

Match the ten most populous urban areas in the
world with its respective continent:
Yellowstone
Watershed:
Clean Air Act:
Clean Water Act:
Land area that delivers water, sediment,
and dissolved substances via small
streams to a major waterway (river)
US federal law designed to control air pollution.
Requires the EPA to develop and enforce
regulations against airborn pollutants known to
be hazardous to human health.
The EPA is charged with implementing pollution control
programs and ensuring water quality standards for
surface
waters. Does not groundwater, wells, artificial lakes.
An irregularly-occurring and complex series of climactic
changes affecting the equatorial Pacific region and beyond
every few years. Tradewinds weaken or reverse, waters
warm near SA and prevent upwelling, affecting marine
food webs.
El Nino:
Baghouse filter:
Air pollution control device that removes particulates out of
air or gas released from commercial processes or
combustion for electricity generation.
A device that removes suspended dust
particles from a gas or exhaust by applying a
high voltage electrostatic charge and
collecting the particles on a charged plate.
Electrostatic precipitator:
Dioxin:
Toxic compound produced during combustion
processes like waste incineration, forest fires, and
backyard trash burning, as well as paper
bleaching and herbicide manufacturing.
18. List three sources of methane that are
amplified by human activities.
1.
Cattle farms
2.
Landfills
3.
Natural gas and petroleum
emissions

Rainshadow effect: A dry area on the
leeward side of a mountain. The
mountain blocks the passage of rain,
producing weather systems by
forcing the prevailing winds
upward, where it condenses and
precipitates before it crosses the top.

porous natural surfaces.
Sun can heat roads and asphalt much hotter than air
temps.
Increased levels of air pollutants (GHG) trap heat.
This review covers topics related to environmental science such as chemical compounds, global protein production, environmental activists, significant events, and the greenhouse effect. It also includes illustrations and questions for better understanding and assessment.
