Unit 7 : Atmospheric Pollution

describes the 6 air pollutants that have been regulated and are used as indicators of general air quality

• Air Act Signifiers
• Secondary Pollutants
• Primary Pollutants
• Criteria Air Pollutants

pollutants that are put directly into the air by human or natural activity.

• Air Act Signifiers
• Criteria Air Pollutants
• Secondary Pollutants
• Primary Pollutants

pollutants that form from chemical reactions that occur when primary pollutants come in contact with other primary pollutants or with naturally occurring substances, such as water vapor.

NGSS.MS-PS1-2

NGSS.MS-PS1-5

Formed when nitrogen oxides and volatile organic hydrocarbons react with heat and sunlight to produce a variety of pollutants.

• Thermal Induced Smog
• Volatile Smog
• Sulfuric Smog
• Photochemical Smog

Tags

NGSS.MS-PS1-2

Molecules that evaporate or sublimate at room temperature.

• Criteria Air Pollutants
• CFCs (Chlorofourocarbons)
• Photochemical Smog
• Volatile Organic Compounds (VOCs)

A change directly from the solid to the gaseous state without becoming liquid

• Transpiration
• Evapotranspiration
• Infiltration
• Sublimation

Tags

NGSS.MS-ESS2-4

Compounds composed of only carbon and hydrogen

• Criteria Air Pollutants
• CFCs (Chlorofourocarbons)
• Volatile Organic Compounds (VOCs)
• Hydrocarbons

When the normal temperature gradient in the atmosphere is altered as the air temperature at the Earth's surface is cooler than the air at higher altitudes.

• Convection of Air Molecules
• Rainshadow Effect
• Hadley Cells
• Thermal Inversion

Tags

NGSS.MS-ESS2-6

Substance (such as a toxic gas) or event (such as drowning) that creates a lack of oxygen in the body.

• Asbestos
• Volatile Smog
• Volatile Organic Compounds (VOCs)
• Asphyxiant

Tags

NGSS.HS-LS1-7

A long, thin, fibrous silicate mineral with insulating properties, which can cause cancer when inhaled.

• Volatile Organic Compounds (VOCs)
• Black Mold
• Radon-222
• Asbestos
