The troposphere is the layer of earth's atmosphere closest to the surface and contains moving air responsible for weather.
True
False
Ozone in the troposphere is good while ozone in the stratosphere is bad.
True
False
What causes the thinning of the ozone layer in the stratosphere?
extremely warm weather in the summer months breaks apart the ozone molecule
cold weather in the winter months breaks apart the ozone molecules
emissions from power plants react with the ozone molecule breaking it down
chlorine atoms from CFCs break apart the ozone molecules in a reaction with UV rays
Which of the following are non-point source pollutants?
auto emissions
airplane emissions
mining operation
fossil fuel power plant
acid rain
Carbon Monoxide is one of the six criteria pollutants covered by the Clean Air Act.
True
False
Smog is generally worse in urban areas.
True
False
Indoor air pollution contains a much small concentration of toxic pollutants than outdoor air pollution.
True
False
Which substances are the major contributors in the formation of acid rain?
NOx and SOx
carbon monoxide and carbon dioxide
particulates and ozone
lead and carbon monoxide
The Clean Air Act has been fairly successful - reducing harmful air pollution from the 6 criteria pollutants over the last few decades.
True
False
Where do non-natural VOCs (volatile organic compounds) come from?
the breakdown of ozone
synthetic chemicals and products
plants
breakdown of smog
Which of the following features apply to the troposphere layer?
layer of the atmosphere closest to earth's surface
layer of the atmosphere farthest from earth's surface
layer of the atmosphere responsible for weather
layer of the atmosphere that contains the ozone layer
densest of all atmospheric layers
Which of the following are correct about ozone?
it is good for human health when present in the troposphere
it is good for human health when present in the stratosphere
it is created when UV rays break apart an oxygen molecule and single O atom joins with another oxygen molecule
it is continuously being destroyed and replenished
it absorbs all UVA, UVB and UVC rays
Dust storms, forest fires and volcanic eruptions are common anthropogenic sources of air pollution.
True
False
Carbon dioxide is one the the six criteria pollutants covered by the Clean Air Act.
True
False
Indoor air pollution contains a higher concentration of toxic pollutants than outdoor air pollution.
True
False
Which of the following are possible effects of acid rain?
leaching of nutrients from soil
corrosion of stone and metals
reduction of the harmful UV rays reaching the surface of the earth
increase in surface temperatures
What is acid mine drainage?
when abandoned mines fill with groundwater which then reacts with certain materials left behind from mining to produce acidic waste water
when acidic water is used to saturate crushed ore to remove the desired mineral
when the tailings from a mine are melted to remove the desired mineral, leaving behind toxic waste
when there is too much acid in the crushed ore for it to be processed
Leaching is a means of chemically processing crushed and separated ore. This process involves
using acidic water to separate the desired material from the ore
using melting to remove the desired material from the ore
using high tech recycling methods to reuse the metal
when underground mines are filled with acidic groundwater
Which of the following are true about mining operations in general?
nearly half of a mine's land area is used for tailings storage
mines are located throughout the entire United States
metals mining is the most common type of mining in the United States
mineral resources are renewable resources
Flotation separation would be the best method for separating out less dense material from crushed ore
True
False
If you were trying to separate out very dense minerals from crushed ore, the best separation method would be
water
flotation
magnetic
any of the above would work
Open pit mining is used when ore deposits are more disseminated and is more dangerous for workers than underground mining.
True
False
Underground mining would be used rather than surface mining because
the ore deposits are more concentrated and located deeper in the crust
the ore deposits are more concentrated and are located close to the surface
the ore deposits are disseminated and located close to the surface
the ore deposits are disseminated and located deeper in the crust
Sedimentary deposits are resources concentrated by the precipitation of material from a body of water
True
False
Which of the following deposit types describes resources concentrated by the precipitation of material from a body of water?
Sedimentary deposits
placer deposits
magmatic deposits
hydrothermal deposits
Mining of rare earth elements produces high amounts of radioactive waste material.
True
False
Leaching is the method in which crushed and separated ore is melted in order to remove the desired material from the rock.
True
False
Non metal deposits, including building material, are the most common resources mined in the United States.
True
False
If you were trying to separate out much less dense minerals from crushed ore, the best separation method would be
water
flotation
magnetic
any of the above methods would work
Open pit mining is used when ore deposits are more disseminated and is safer for workers than underground mining.
True
False
Underground mining is generally more dangerous for workers but produces less waste than surface mining.
True
False
Magmatic ore deposits are created when resources are concentrated within a magma body by processes that occur during cooling of the magma
True
False
When valuable resources are concentrated within a magma body by processes that occur during cooling of the magma, the deposits are known as
magmatic deposits
hydrothermal deposits
placer deposits
sedimentary deposits
Which statement is correct about rare earth elements?
they have special magnetic and electrical properties that make them unique
they are difficult to process
processing them is difficult to do in an environmentally friendly, yet economical way
all of the above
E-waste can safely be disposed of in municipal landfills.
True
False
Burning waste produces more CO2 emissions than coal.
True
False
The major risks to burying our waste in landfills is
the land can never be used for any other purpose
some older landfills will leak leachate
landfills produce methane
all of the above
The construction of landfills is on the rise in the US and there is plenty of room for all of the waste we produce.
True
False
What is a major drawback to recycling programs?
It is getting more expensive to do
the cost of some recycled goods can actually be more than products made from new resources
recycling plastic may have zero environmental benefits
all of the above
The US stockpile of used tires has been shrinking as we have found secondary uses for the used tires.
True
False
Which of the following are some of the benefits of plastics? (choose all that apply)
lightweight
reusable
numerous benefits in society
renewable resource
expensive
What are some of the drawbacks to the abundant use of plastics in society? (choose all that apply)
never degrades
release toxic chemicals when disposed of improperly
recycling plastic is getting more difficult and expensive
lightweight
The U.S. creates a disproportional amount of waste relative to our population.
True
False
Only municipal solid waste and certain industrial waste are collected and disposed of; most waste is simply left on the surface.
True
False
E-waste contains toxic substances and cannot be sent to municipal landfills.
True
False
The major benefit to burning waste is that it produces almost no harmful emissions.
True
False
Sanitary landfills are the best ways to reduce pollution and odors from MSW.
True
False
