Is the condition of the Earth's atmosphere at a particular time and place.
What is Weather
100
A mixture of gaseous elements and compounds
What is Air
100
Solid particles and gases that are released into the air
What are emmissions
100
Precipitation that is more acidic than normal
What is Acid rain
100
The trapping of heat near Earth's surface
What is the Greenhouse effect
200
This contains gases that living things need to survive.
What is atmosphere
200
Earth's atmosphere is made up of 78% of this and 21% of this (along with carbon dioxide, water vapor, and many other trace gases and particles of liquids and solids).
What are nitrogen and oxygen
200
This is the largest source of emissions, but air pollution can also be caused by natural causes such as an erupting volcano.
What are motor vehicles.
200
This type of air pollution can be caused by dust, pet hair, air fresheners, asbestos, tobacco smoke, and oil-based paints, glues and cleaning supplies.
What is indoor air pollution
200
This theory claims that the increase in carbon dioxide has caused the greenhouse effect to become stronger.
What is global warming
300
Keeps the Earth's surface warm enough for water to exist as a liquid which living things need to survive.
What is atmosphere
300
A change to the atmosphere that has harmful effects to the health of humans and other living things.
What is air pollution
300
Formed from certain gases in the air that react with the sunlight to produce air pollution.
What is photochemical smog
300
A layer of the upper atmosphere that protects people from the effects of too much ultraviolet radiation.
What is ozone layer
300
Most scientists use computer models that calculate the effects of changes in the atmosphere to make these predictions.
What is climate predictions
400
The atmosphere protects living things from these two things.
What are radiation and meteoroids
400
Air pollution contains substances which can be solid particles that cause pollution
What is chemicals
400
The major toxic chemical found in smog
What is ozone
400
The difference between ozone as a pollutant and ozone as a helpful gas is this.
What is location
400
Two properties of air
What are pressure and density
500
Our house number
What is 110
500
Can impact the environment
What is pollution
500
Condition in which a layer of warm air prevents cooler air from escaping into higher parts of the atmosphere. It traps polluted air close to the ground.
What is temperature inversion
500
The loss of ozone was blamed on the use of this.
What is chlorofluorocarbons.
500
The amount of mass in a given volume of air is also know as this.
