EES 3.4 Camber
| Term | Definition |
|---|---|
| Sun | The star at the center of our solar system that provides solar radiation (energy) to Earth. |
| Earth | The planet we live on; it absorbs and reflects energy from the Sun. |
| Solar Radiation | Energy from the Sun that travels through space as light and heat. |
| Thermal Energy | Heat energy; the energy something has because of its temperature. |
| Energy In | The solar radiation Earth receives from the Sun. |
| Energy Out | Heat (infrared radiation) that Earth releases back into space. |
| Heat Absorption | When a material takes in heat energy. |
| Heat Retention | How well a material holds onto heat instead of releasing it. |
| Land vs. Water | Land heats up and cools down quickly. Water heats and cools slowly because it has higher heat retention. |
| Circulation | The movement of air (atmosphere) or water (oceans) that redistributes heat around Earth. |
| Atmosphere | The layer of gases surrounding Earth. |
| Troposphere | The lowest layer of the atmosphere where weather occur |
| Uneven Heating | The Sun heats Earth’s surface unevenly (more at the equator, less at the poles), causing wind and weather patterns. |
| Weather Patterns | Short-term atmospheric conditions like storms, rain, wind, and temperature changes. |
| Climate Impact | Long-term effects on Earth’s climate due to natural or human causes. |
| Land Cover | The physical material on Earth’s surface (forests, cities, water, ice, grasslands). |
| Urban Heat Island | When cities are warmer than surrounding rural areas because buildings and pavement absorb and retain heat. |
| Albedo Effect | The measure of how much sunlight a surface reflects. |
| Reflects | Bounces energy away. |
| Bounces energy away. | Takes in energy. |
| Oxygen (O₂) | A gas in the atmosphere (about 21%) that humans and animals breathe. |
| Nitrogen (N₂) | The most abundant gas in the atmosphere (about 78%). |
| Greenhouse Gases | Gases that trap heat in the atmosphere, warming Earth. |
| Water Vapor (H₂O) | The most abundant greenhouse gas; increases as temperature rises. |
| Carbon Dioxide (CO₂) | Released by burning fossil fuels, respiration, and volcanoes; major contributor to climate change. |
| Methane (CH₄) | Produced by livestock, landfills, and natural gas; very powerful greenhouse gas. |
| Nitrous Oxide (N₂O) | Released from fertilizers and industrial processes; strong greenhouse gas. |
| Hydrochlorofluorocarbons (HCFCs) | Man-made gases once used in refrigerants; harm ozone and trap heat. |
| Hydrofluorocarbons (HFCs) | Man-made greenhouse gases used in cooling systems; trap heat but don’t damage ozone. |
| Ozone (O₃) | A gas found in two places: |
| Ice Core | A cylinder of ice drilled from glaciers or ice sheets that contains trapped air bubbles used to study past climates. |
| Geologic Sample | Rocks or sediments studied to learn about Earth’s past climate and conditions. |
