| main greenhouse gases | carbon dioxide, methane, water vapor |
| greenhouse effect | a natural process - warming of the earth because of the insulating properties of the greenhouse gases |
| the type of heat radiated from land & ocean back into the atmosphere | infrared heat |
| to much heat retained by greenhouse gases could result in this event | global warming |
| pollutants from this type of activity could potentially increase greenhouse gases | use of fossil fuels |
| source of energy for all process on Earth | The Sun |
| Plants and trees absorb this gas as they grow | carbon dioxide |
| use of this type of technology can decrease emissions of pollutants contributing to global warming | use of wind and solar power, hydrogen produced from renewable sources, biofuels (produced from crops), natural gas, and nuclear power |
