| Greenhouse gasses | gasses in the atmosphere that trap infrared ligth |
| infrared light | wave length of light that is too long for us to see and is radiated heat |
| ultraviolet light | wavelength of light that is too short for us to see and can cause skin cancer and sunburns |
| Ozone layer | layer of stratosphere with lots of ozone that blocks ultraviolet light |
| Troposphere | bottom layer of atmosphere where greenhouse warming occurs |
| Greenhouse warming or greenhouse effect | warming of atmosphere caused by gasses trapping infrared raditation |
| Climate change | changes to average weather conditions caused by greenhouse warming |
| Carbon Dioxide | a greenhouse gas that comes from, among other things burning fossil fuels |
| Fossil fuels | energy sources made from crude oil, natural gas, and coal including gassoline |
| Methane | a greenhouse gas that comes from bacteria in the digestive tracts of cattle |
| Climate | average weather conditions for a region |
| weather | the conditions in the atmosphere, such as wind, temperature, and moisture, at a particular place and time |
| Light spectrum | the range of electromagnetic radiation from radio waves to gamma rays |
| visible light | a small part of the light spectrum that goes from red to violet |
| radio waves | an example of low energy long wavelength light |
| x-rays | an example of high energy short wave light |
| deforestation | cutting down trees |
| nitrogen | most abundant gas in the atmosphere |
| oxygen | makes up about 20% of the atmosphere |
| radiation | light or heat moving as electromagnetic waves |
| conduction | heat moving by touch |
| convection | heat moving by rolling currents in a liquid or gas |
| water vapor | water in the invisible gas state |
