Structure of the Atmosphere
This is the layer of gases (like air) surrounding a planet, held by gravity, providing us oxygen, weather, and protection from the sun.
What is Atmosphere?
This is the temperature over a long period of time.
What is Climate?
This is a thick, grey air pollution from factories burning fossil fuels like coal.
This is released by burning fossil fuels and reacts with sunlight to form photochemical smog.
What is Nitric Acid?
This is the contamination of air inside buildings by harmful substances like smoke, mold, chemicals, etc.
What is Indoor Air Pollution?
This has 75-80% of the Earth's air mass and is closest to the Earth's surface.
What is Troposphere?
This is the presence of chemicals in the atmosphere that could potentially harm ecosystems and organisms.
What is Air Pollution?
This is a type of air pollution that forms a hazy, brownish layer when sunlight reacts with pollutants.
What is Photochemical Smog?
This is released by burning coal and refining oil. (HINT - Has DI in the name).
What is Sulfur Dioxide?
This is a naturally occurring radioactive gas that is invisible and odorless.
What is Radon?
This is 17–48 kilometers above Earth’s surface and has a higher concentration of ozone (O3).
What is Stratosphere?
These are harmful substances emitted directly into the atmosphere from a source.
What are Primary Pollutants?
These are carbon-based chemicals that easily turn into gases or vapors at normal room temperature and pressure.
What are Volatile Organic Compounds?
This is a chemical composition of industrial smog.
What is Sulfuric Acid?
This is the main U.S. federal law controlling air pollution.
What is Clean Air Act?
This filters 95% of harmful UV radiation and allows life to exist on land.
What is Ozone Layer?
What are Secondary Pollutants?
These are harmful air pollutants, like a sticky, irritating component of smog, formed when sunlight hits traffic exhaust.
What are Peroxyacyl Nitrates?
This is caused by coal-burning power plants and motor vehicle emissions.
What is Acid Deposition?
This is an environmental policy that provides economic incentives to reduce pollution.
What is Emissions Trading?
This is the current temperature or the temperature over a short period of time.
What is Weather?
These are tiny solid bits or liquid droplets floating in the air that typically come from traffic, industry, fires, etc.
What is Suspended Particulate Matter?
This is is a weather phenomenon where a layer of warm air traps a layer of cool air near the Earth's surface.
What is Temperature Inversion?
This is the gradual thinning of the atmosphere's ozone layer which is mainly due to human activities.
What is Ozone Depletion?
