
 In
drives the water cycle?
Solar radiation from the sun
the space provided draw a picture of
the water cycle and label the sun,
condensation, precipitation and

Environmental Science II
Environmental Science II
 Based
on the chart below which area of
the world would have the greatest water
stress?

Asia
Environmental Science II
 Name



at least six renewable resources.
Timber
Soil
Water
Wild animals
Solar

Geothermal
Environmental Science II
 Phoenix
has replaced desert with
concrete and asphalt, how has that
affected temperature over the past 50
years?

Night time low temperatures have
increased by 10ºF
Environmental Science II
 What
is the leading
cause for the
increase in CO2 in
the atmosphere?

Increasing
consumption of
fossil fuel
Environmental Science II
 The
fluctuations in
the graph represent
increases and
decreases in
photosynthesis
during different
seasons in the
northern
hemisphere.
Environmental Science II
 What
happens to the energy from the sun
that reaches the earth?

It is trapped by the earth’s atmosphere; if
the earth did not have an atmosphere the
energy would be reflected back into
space.
Environmental Science II
 Name
some of the threats posed by
climate change?

Rising sea levels threaten people who live
by coastal areas
 How
can individuals reduce emissions
from cars?

Use public transportation
Environmental Science II
 What
can be done to reduce climate
change?

Plant trees that take in carbon dioxide
during photosynthesis
 What
makes up the greenhouse gasses
that trap heat near the earth?

Water vapor and carbon dioxide
Environmental Science II
 How

do scientists use proxy indicators?
Scientist use proxy indicator such as ice
cores to learn what climates were like in the
past
Environmental Science II
 What

is the source of most air pollution?
Combustion of fossil fuels
 Name
a United States regulation that sets
limits on specific air pollution.

The Clean Air Act
Environmental Science II
 How
has the climate changed since the
Jurassic period?

During the Jurassic period there was a
great deal of volcanic activity causing
higher levels of CO2 in the atmosphere
Environmental Science II
 What
is the difference between weather
and climate?

Weather is the atmospheric condition at a
specific point in time, climate is the
atmospheric condition over a long period
of time.
Environmental Science II
 How
is most of the electricity used in the
United States generated?

Combustion of fossil fuels
 Who
uses more energy developed
nations or under-developed nations?

Developed nations
Environmental Science II
 Why
is the use of natural gas growing
faster than other forms of fossil fuels?


How is most oil used in the United States?


It creates less air pollution
Transportation
How can fossil fuels be used directly?

A gas stove
Environmental Science II
 What
is the greatest limitation to some
forms of renewable energy?

Geothermal energy is geographically
limited
 What
is the major disadvantage of
nuclear energy?

How to dispose of radioactive waste
Environmental Science II
 How
is biomass
used as an energy
source?

Burning wood in a
fireplace for heat
Environmental Science II
 How

are fossil fuels formed?
Fossil fuels are formed in nature from the
remains of ancient organisms, but it takes
millions of years so they are considered
nonrenewable
Environmental Science II
 Name

an example of solar energy use.
Passive solar energy can be used to heat
homes and buildings and photo voltaic
cells can be used to generate power to
homes
Environmental Science II
 Are
there limitations to renewable energy
sources? If so what are they?

Geographic limitations
 How
does the development of an oil field
affect ecosystems?

Pollutes air and streams
Environmental Science II
 What
are the advantages of renewable
energy sources?

They do not produce greenhouse gasses
 How
can waste from food scraps be
reduced?

Composting
Environmental Science II

Where does most waste
end up?


In landfills
How do landfills impact
the environment?

The majority of our waste
ends up in disposal sites
that take up large
amounts of land and
contribute to both air
and water pollution
Environmental Science II

How can the negative impact of hazardous
waste be reduced?


What are the benefits of waste reduction?


Reduce the amount of hazardous waste
produced
The economic benefits include lower cost
associated with waste disposal
How can we reduce the amount of plastic
that ends up in landfills?

By using reusable water bottles, recycling water
bottles and drinking from fountains
Environmental Science II
 Name
a hazardous waste and describe
how it affects the environment.

Hazardous waste such as electronic
devices can leach heavy metals into
groundwater
 E-waste
Environmental Science II
 What
does an ecological footprint
measure?

The environmental impact of an individual
in terms of the total amount of land and
water required to provide the raw materials
and products needed and the disposal of
the resulting waste.
Environmental Science II
 What
can you do to lower your
ecological footprint?


Eat less meat and eat more vegetables
What is sustainable living?

Adjusting your lifestyle in an attempt to
reduce the use of nonrenewable resources
