100
Meteors burn up as they pass through this layer
What is the mesosphere?
100
The layer of gases that surround the earth is called this.
What is the atmosphere?
100
Substances produced from wildfire and volcanic eruptions are known as this.
What is natural pollutants?
100
This color coded chart can alert people to problems in the air.
What is the air quality index?
100
This layer of the atmosphere is the first that an astronaut would pass through on reentry from outerspace.
What is the exosphere?
200
Clouds, weather,and airplanes all are found in this layer
What is the troposphere?
200
This gas is the most abundant in the Earth's atmosphere.
What is nitrogen?
200
This energy source is the most damaging to Earth's atmosphere.
What is fossil fuel?
200
If the US passes laws to decrease air pollution, then Americans do not need to worry about air quality anymore. True/ False
What is False? Air is a "shared resource". Sometimes air quality is a simple local issue, other times, what our neighbors put in the air is carried into our air space by wind. For example, the chemicals that cause acid rain are not just a local issue, that rain may fall miles from the factory that acidified it.
200
The name for a form of oxygen with 3 oxygen atoms in each molecule.
What is ozone?
300
In this layer, the ozone layer deflects ultraviolet rays back into space.
What is the stratosphere?
300
In the early years following the formation of Earth, this gas was not present in Earth's atmosphere.
What is oxygen?
300
When emissions from fossil fuel burning factories react with water vapor, this damaging substance can be formed.
What is acid rain?
300
The single most important change humans could make to have a positive impact on the air quality is this.
What is stop burning fossil fuels?
300
The two most abundant gases in Earth's present atmosphere are these.
What are nitrogen and oxygen?
400
This layer contains the ionosphere.
What is the thermosphere?
400
The earliest atmospheric gases came from this process.
What is off gassing from the core of the Earth and volcanic eruptions?
400
Increasing levels of this can cause increased skin cancer and cataracts in humans, kill phytoplankton, and cause plants to become diseased.
What is ultraviolet radiation?
400
These are some alternative energy sources that are "cleaner" for our air
What are solar, water, and wind power?
400
A brown haze that forms when ground-level ozone reacts with sunlight
What is smog?
500
This layer contains most of the atmospheric water vapor and gasses.
What is the troposphere?
500
Thanks to this process, free oxygen became available in this atmosphere?
What is photosynthesis?
500
These chemical compounds can destroy ozone molecules.
What are CFC's or chlorofluorocarbons?
500
These people are most sensitive to air quality issues?
Who are the very young, very old, the sick, those with respiratory problems, and those who are extremely active outdoors?
500
This is what happens when warm air is above cool air in the troposphere and it causes pollutants to get trapped.
What is a temperature inversion?
