| Term | Definition |
|---|---|
| Greenhouse gases | Gases in Earth’s atmosphere that trap heat and help keep the planet warm (for example CO₂, CH₄, and water vapor). |
| Greenhouse effect | The natural process where greenhouse gases trap heat from the Sun in Earth’s atmosphere, warming the planet. |
| Climate | The long-term average pattern of weather in a place, including temperature and precipitation. |
| Human | A person; relating to people or human activities |
| Absorption of heat | The process by which a substance takes in heat energy and becomes warmer. |
| Atmospheric heating | The warming of Earth’s atmosphere due to absorbed energy, especially from greenhouse gases trapping heat. |
| Water vapor (H₂O | A gas form of water in the atmosphere; the most abundant greenhouse gas. |
| Carbon dioxide (CO₂) | A colorless gas released by breathing, burning fossil fuels, and natural processes; a major greenhouse gas. |
| Methane (CH₄) | A powerful greenhouse gas released from natural sources and human activities like agriculture and fossil fuel production. |
| Nitrous oxide (N₂O) | A greenhouse gas released from agricultural practices, fertilizers, and combustion processes. |
| Hydrochlorofluorocarbons (HCFCs) | Man-made gases once used in refrigeration and air conditioning that contribute to global warming and ozone depletion. |
| Hydrofluorocarbons (HFCs) | Man-made greenhouse gases used in refrigeration and cooling systems that do not damage the ozone layer but strongly trap heat |
| Ozone (O₃) | A gas that forms a protective layer in the upper atmosphere blocking harmful ultraviolet radiation; near the ground, it can be a pollutant. |
| Burning fossil fuels | The use of coal, oil, or natural gas for energy, which releases greenhouse gases into the atmosphere. |
| Refrigerant | A substance used in cooling systems like refrigerators and air conditioners to absorb and release heat. |
| Respiration | The process by which living organisms breathe and release carbon dioxide. |
| Natural forest fires | Fires started by natural causes such as lightning that release carbon dioxide and other gases into the atmosphere. |
| Emissions | Gases or substances released into the air, especially from human activities like transportation and industry. |
| Temperature | A measure of how hot or cold something is. |
| Precipitation | Water that falls from the atmosphere to Earth’s surface, such as rain, snow, sleet, or hail. |
| Agricultural practices | Methods used in farming, such as growing crops or raising livestock, which can produce greenhouse gases. |
| Volcanic eruptions | Natural events where volcanoes release lava, ash, and gases into the atmosphere, sometimes affecting climate. |
