Air particle review!

Most often cited as the main causative factor of acid deposition SO2

Released by aerosol cans, refrigerators, and air conditioning units CFCS

Implicated in human neurological damage lead

These are the greenhouse gases CO2, CH4, N2O (nitrous oxide), sulfur hexafluoride, water vapor!

Main greenhouse gas CO2

Is the major pollutant that electrostatic precipitators are designed to remove from power plant smokestack emissions. Particulates

Banned by the montreal protocol

Has a stronger affinity for hemoglobin than oxygen has. CO

Is a flammable gas produced by landfills and livestock. CH4 (methane)

Is mostly produced by coal fired power plants and is most probable contributor to global warming

Found in old plumbing pipes and fixtures and some ceramic GLAZES lead

Composed of fibers known to cause lung disease asbestos

Emitted from most manufactured building materials and furniture Formaldehyde

Radioactive gas found in older residential homes with poor ventilation Radon

The underlying bedrock under houses is the biggest source of this

21% of the atmosphere is made up of this Oxygen

Consumption of fossil fuels leads to this being released in the air

78 % of the atmosphere is made of this nitrogen

Created by sunlight acting on NOx and VOC , photocopiers, cars, industry, gas vapors, chemical solvents, incomplete fuel combustion products O3

When this Reacts with UV light it creates photochemical smog (greenhouse gases) VOC’s, nitrous oxides (n20)

This is the product of primary pollutants reacting with uv (what makes up photochemical smog)

(end gases) What is the primary reason for earth’s seasons? Tilt of the the earth’s axis of rotation

Where the protective ozone layer is located

Region of the atmosphere responsible for our weather

Layers of our atmosphere (in order from closest to earth to most distant) Troposphere, stratosphere, mesosphere, thermosphere, exosphere

The phenomenon causing global warming happens in this layer troposphere

The three main anthropogenic sources of gaseous air pollutants in the United States are Industry, transportation, energy

How will global warming affect the hydrologic cycle? Increased evaporation/ humidity

What is the main cause of the increase in CO2? Increased consumption of fossil fuels

There are very obvious annual fluctuations in CO2 levels… Why? Seasonal photosynthetic activity of green plants that absorb carbon dioxide

What natural disaster event would lead to a cooling of the earth’s atmosphere? Volcanic eruption

List possible effects of a warming atmosphere Expanded ranges of tropical diseases More intense hurricanes and typhoons Increased crop damage from pests and diseases

Why do we need some greenhouse gases in our atmosphere? Trap/absorb infrared rays to make the earth warm enough for plants/animals to live on

In most large cities, the majority of ground-level ozone comes from what source? Motor vehicle exhaust

Acid rain is defined by a Low or high pH?

When soil becomes more acidic previously insoluble compounds can turn into elements such as __________ Aluminum, sulphate, calcium, magnesium, H+

How will global warming effect the oceans? Rising sea levels, will submerge low lying areas (coastal flooding)

How is the melting of polar ice caps considered a positive feedback loop when it comes to the warming of the atmosphere? Causes more ocean water to be exposed to sunlight- hence further warming the oceans and the earth in general (positive feedback loop)

WhAT is used to reduce SO2 emissions from coal-burning power plants? Wet-scrubber unit

Which global piece of legislation is fighting to reduce greenhouse gases? The Kyoto Protocol-an international treaty which extends the 1992 United Nations Framework Convention on Climate Change (UNFCCC) that commits State Parties to reduce greenhouse gas emissions, based on the premise that (a) global warming exists and (b) human-made CO2 emissions have caused it.

Order the following from highest to lowest albedo: snow, water, ice, forest, light desert sand, asphalt, dark roof, light roof Snow, ice, light roof, light desert sand, forest, asphalt, dark roof

What are the 6 criteria air pollutants used to determine air quality? Particle Pollution (particulate matter) Ground-level ozone. Carbon monoxide. Sulfur oxides. Nitrogen oxides. Lead.
