| Term | Definition |
|---|---|
| Greenhouse gases | Gases in the atmosphere that trap heat and keep Earth warm. Examples include carbon dioxide, methane, and water vapor. |
| Greenhouse effect | The natural process where greenhouse gases trap heat from the Sun. This keeps Earth warm enough for life. |
| Climate | The average weather conditions of a place over many years. Includes temperature, rainfall, and seasons. |
| Human climate | How human activities affect Earth’s climate. Examples include burning fossil fuels and deforestation. |
| Absorption of heat | When an object or surface takes in heat energy. This causes it to warm up. |
| Atmospheric heating | The warming of Earth’s atmosphere by trapped heat. It happens because greenhouse gases hold heat in the air. |
| Water vapor (H₂O) | Water in gas form found in the atmosphere. It is the most abundant greenhouse gas. |
| Carbon dioxide (CO₂) | A greenhouse gas released by breathing, burning fossil fuels, and factories. It is a major cause of climate change. |
| Methane (CH₄) | A strong greenhouse gas released by livestock, landfills, and natural gas leaks. It traps more heat than carbon dioxide. |
| Nitrous oxide (N₂O) | A greenhouse gas released mainly from agriculture and fertilizers. It also contributes to global warming. |
| Hydrochlorofluorocarbons (HCFCs) | Man-made gases used in older cooling systems. They trap heat and damage the atmosphere. |
| Hydrofluorocarbons (HFCs) | Man-made greenhouse gases used in refrigerators and air conditioners. They trap large amounts of heat. |
| Ozone (O₃) | A gas that forms a layer protecting Earth from harmful UV rays. It can also act as a greenhouse gas. |
| Burning fossil fuels | Using coal, oil, or natural gas for energy. This releases large amounts of carbon dioxide. |
| Refrigerant | A chemical used in refrigerators and air conditioners. Some refrigerants are powerful greenhouse gases. |
| Respiration | The process by which living things breathe. It releases carbon dioxide into the atmosphere. |
| Natural forest fires | Wildfires started by natural causes like lightning. They release carbon dioxide and smoke into the air. |
| Emissions | Gases or particles released into the atmosphere. Often come from cars, factories, and power plants. |
| Temperature | A measure of how hot or cold something is. It affects weather and climate patterns. |
| Precipitation | Water that falls from clouds as rain, snow, sleet, or hail. It is a key part of climate. |
| Agriculture practices | Farming activities such as raising livestock and using fertilizers. They can release greenhouse gases into the air. |
| Volcanic eruptions | When volcanoes release lava, ash, and gases. They can affect Earth’s climate for short periods. |
