Nilin - EES 3.4
EES 3.4
| Question | Answer |
|---|---|
| Heat absorption | The process of taking in heat energy from a source. |
| Heat retention | The ability of a material or substance to hold onto heat over time. |
| Solar radiation | Energy emitted by the sun in the form of light and heat. |
| Thermal energy | The total energy of moving particles in a substance; heat energy. |
| climate impact | The effect that natural or human factors have on Earth’s climate system. |
| weather patterns | Recurring atmospheric conditions (temperature, wind, precipitation, pressure) in a region over time. |
| Land cover | The physical material covering Earth’s surface (forests, grass, water, concrete, ice, etc.). |
| oxygen | A gas in Earth’s atmosphere (about 21%) essential for respiration and combustion. |
| nitriogen | A colorless gas that makes up about 78% of Earth’s atmosphere. |
| albedo | The measure of how much sunlight a surface reflects. Light surfaces (like ice) have high albedo; dark surfaces (like asphalt) have low albedo. |
| greenhouse gasses | Gases that trap heat in Earth’s atmosphere, warming the planet (e.g., CO₂, CH₄, H₂O, N₂O). |
| land vs water | Land heats and cools quickly; water heats and cools slowly because it absorbs and stores more heat. |
| urban heat effect | A city area that is significantly warmer than surrounding rural areas due to buildings, pavement, and reduced vegetatio |
| surface | The outermost layer of Earth (land or water) that interacts with the atmosphere. |
| troposphere | The lowest layer of Earth’s atmosphere where weather occurs. |
| atmosphere | The layer of gases surrounding Earth |
| energy in | Solar energy entering Earth’s atmosphere from the sun. |
| energy out | Heat energy radiated back into space from Earth. |
| Sun | The star at the center of our solar system that provides light and heat to Earth. |
| earth | The third planet from the sun; the only known planet that supports life. |
| reflect | Bounces energy (like sunlight) off a surface. |
| absorbs | Takes in energy rather than reflecting it. |
| circulation | – The movement of air or water that distributes heat around the planet. |
| ice core | A cylindrical sample drilled from ice sheets or glaciers that contains trapped air bubbles used to study past climates. |
| geoligocal sample | Rock, sediment, or fossil material used to study Earth’s history. |
| water vapor | Gaseous form of water; the most abundant greenhouse gas. |
| Co2 | A greenhouse gas released by respiration, burning fossil fuels, and volcanic activity. |
| methane | A powerful greenhouse gas produced by livestock, wetlands, and fossil fuel extraction. |
| niros oxide | A greenhouse gas released from fertilizers, combustion, and industrial processes. |
| Hydrochlorofluorocarbons (HCFCs) | Man-made gases once used in refrigeration; contribute to ozone depletion and act as greenhouse gases |
| Hydrofluorocarbons (HFCs | Man-made greenhouse gases used in refrigeration and air conditioning; do not deplete ozone but trap heat. |
| ozone | – A gas made of three oxygen atoms. In the stratosphere, it protects Earth from harmful UV radiation; at ground level, it is a pollutant. |
