Study Notes
Evaporation
Definition: Evaporation is the process by which water is transformed from its liquid state to water vapor.
Key Factors:
- Temperature: Evaporation increases with temperature. Higher temperatures provide more energy for molecules to escape the surface.
- Humidity: Evaporation decreases with high humidity. When the air is already saturated with water vapor, it's harder for more water to evaporate.
- Wind: Evaporation increases with wind. Wind helps to remove the water vapor from the surface, allowing more evaporation to occur.
- Surface Area: Evaporation increases with surface area. A larger surface area exposes more water molecules to the air, allowing for more evaporation.
Types of Evaporation:
- Surface Evaporation: Evaporation from the surface of oceans, lakes, and rivers.
- Plant Transpiration: Evaporation from plants, which release water vapor into the air through their leaves.
- Soil Evaporation: Evaporation from the soil, which occurs when the soil is moist and the air is dry.
Importance of Evaporation:
- Water Cycle: Evaporation is the first step in the water cycle, allowing water to move from the Earth's surface to the atmosphere.
- Weather Patterns: Evaporation helps to create weather patterns, such as clouds and precipitation, by adding water vapor to the air.
- Ecosystems: Evaporation plays a crucial role in maintaining healthy ecosystems, as it helps to regulate the water balance and support plant growth.

Factors Affecting Evaporation
- Higher temperatures increase evaporation, providing more energy for molecules to escape the surface.
- Evaporation decreases with high humidity, as the air is already saturated with water vapor.
- Wind increases evaporation by removing water vapor from the surface, allowing more evaporation to occur.
- A larger surface area exposes more water molecules to the air, increasing evaporation.
