Study Notes
Weather and Earth Systems
- Weather encompasses atmospheric conditions like temperature, precipitation, and wind.
- Earth's layers include the lithosphere (rock), hydrosphere (water), and atmosphere.
- Albedo is the reflectivity of a surface, impacting how much solar radiation is absorbed or reflected.
- Heat transfer occurs through conduction (direct contact), convection (fluid movement), and radiation (electromagnetic waves).
- Greenhouse gases (e.g., carbon dioxide, methane) trap heat in the atmosphere, leading to the greenhouse effect.
- Climate change refers to long-term shifts in global temperatures and weather patterns, frequently attributed to human activities.
- Heat capacity describes the amount of heat needed to raise a substance's temperature.
- Heat source generates or supplies heat.
- Heat sink absorbs or dissipates heat.
- Deep ocean currents are large-scale movements of water driven by temperature and salinity differences.
- Weather cycle includes processes like evaporation, condensation, and precipitation.
- André Robert is potentially a person or entity related to weather or climate. (More context is needed for complete note on this.)
