Study Notes
Evaporation
Definition: Evaporation is the process by which liquid water is transformed into water vapor.
Key Factors:
- Temperature: Higher temperatures increase the rate of evaporation.
- Humidity: Lower humidity allows for faster evaporation.
- Wind: Increased wind speed enhances evaporation.
- Surface area: Larger surface areas of water lead to greater evaporation.
Types of Evaporation:
- Surface evaporation: Occurs from the surface of oceans, lakes, and rivers.
- Transpiration: Evaporation from plants and soil.
- Evapotranspiration: Combination of transpiration and surface evaporation.
Importance:
- Water cycle: Evaporation is the first step in the water cycle, driving the movement of water throughout the Earth's systems.
- Weather patterns: Evaporation influences the formation of clouds and precipitation.
- Ecosystems: Evaporation plays a crucial role in regulating the water balance in ecosystems.
Interesting Facts:
- 95% of evaporation: Occurs from the oceans, with the remaining 5% from land surfaces.
- Energy requirement: Evaporation requires energy from the sun, which is approximately 540 calories per gram of water.
Learn about the process of evaporation, its key factors, types, importance, and interesting facts. Understand how evaporation affects the water cycle, weather patterns, and ecosystems.
