CFC's Chloroflourocarbons; chemicals that create holes in the ozone layer
UV radiation harmful sunlight that causes skin cancer
Troposphere layer that contains all life, water, and weather
Stratosphere layer that contains ozone
Mesosphere layer where meteors normaly burn up
Thermosphere hottest layer
Exosphere layer that borders with space where satellites orbit
Greenhouse Effect certain gasses in Earth's atmosphere trap heat
Global Warming the average temperature of Earth has been rising over the past 100 years
Carbon Dioxide the greenhouse gas that Scientists are most concerned about
human activities that contribute to global warming burning fuel, generating electricity, deforestation
