The distance from the equator measured in degrees north or south of the equator.
Movement of air within the atmosphere.
Prevailing Winds
Trade winds, westerlies, and polar easterlies.
The tilt of Earth's axis.
Ozone Layer
An area in the stratosphere where ozone is highly concentrated.
Ozone Hole
A thinning of stratospheric ozone that occurs over the poles during the spring.
Polar-Stratospheric Clouds
When temperatures fall below about -80 degrees, high-altitude clouds made of water and nitric acid begin to form.
Ozone Thinning on Humans
Damages DNA.
Montreal Protocol
International agreement to limit CFC production.
Greenhouse Effect
Sunlight streams through the atmosphere and heats the Earth.
Greenhouse Gases
The gases the do absorb and radiate heat.
5 Major Greenhouse Gases
Carbon Dioxide, CFCs, Methane, Nitrous Oxide, and Water Vapor.
Global Warming
The increasing greenhouse gases in our atmosphere result in increasing the average temperature on Earth.
The Intergovernmental Panel on Climate Change.
Kyoto Protocol
Developed countries to decrease emissions of carbon dioxide and other greenhouse gases by an average of 5 percent below their 1990 levels by 2012.
El Nino
Winds push warm water eastward in the Pacific Ocean.
Atmospheric CO2
Increases when fossil fuels are burned.
Stratospheric Ozone
Destroyed by CFCs.
