| Question | Answer |
|---|---|
| Heat absorption | The process of taking in heat energy. |
| Heat retention | The ability to hold or keep heat over time. |
| Solar radiation | Energy from the Sun that travels to Earth as light and heat. |
| Thermal energy | Heat energy caused by the movement of particles. |
| Climate impact | Long-term effects on Earth’s climate system. |
| Weather patterns | Repeated or common types of weather in an area. |
| Land cover | The physical material on Earth’s surface (forest, water, cities, etc.). |
| Oxygen (O₂) | A gas in the atmosphere needed for breathing and burning. |
| Nitrogen (N₂) | The main gas in Earth’s atmosphere (about 78%). |
| Greenhouse gases | Gases that trap heat in the atmosphere. |
| Albedo effect | How much sunlight a surface reflects back into space. |
| Land vs water | Land heats and cools faster; water heats and cools more slowly. |
| Urban heat island | Cities being warmer than nearby rural areas due to buildings and pavement. |
| Surface | The outer layer of Earth (land or water). |
| Troposphere | The lowest layer of the atmosphere where weather happens. |
| Uneven heating | Different areas of Earth warming at different rates. |
| Atmosphere | The layer of gases surrounding Earth. |
| Energy in | Solar energy coming into Earth’s system. |
| Energy out | Heat energy leaving Earth and going into space. |
| Sun | The star that provides light and heat to Earth. |
| Earth | The planet we live on. |
| Reflects | Bounces energy or light off a surface. |
| Absorbs | Takes in energy or light. |
| Circulation | The movement of air or water around Earth. |
| Ice core | A cylinder of ice drilled from glaciers to study past climate. |
| Geologic sample | Rock or soil used to study Earth’s history. |
| Water vapor (H₂O) | Water in gas form; a greenhouse gas. |
| Carbon dioxide (CO₂) | A greenhouse gas from breathing and burning fuels. |
| Methane (CH₄) | A powerful greenhouse gas from livestock, wetlands, and fossil fuels. |
| Nitrous oxide (N₂O) | A greenhouse gas from farming and industry. |
| Hydrochlorofluorocarbons (HCFCs) | Man-made gases once used in cooling; damage ozone and trap heat. |
| Hydrofluorocarbons (HFCs) | Man-made greenhouse gases used in refrigeration. |
| Ozone (O₃) | A gas that protects Earth from harmful UV radiation (in the upper atmosphere). |
