Lesson 4: The Water Cycle and Forces 🌧️
Vocabulary
- Evaporation: The process of turning from liquid into vapor.
- Condensation: The process by which water vapor cools and turns back into liquid droplets.
- Precipitation: Any form of water that falls from the atmosphere, e.g., rain, snow, sleet.
- Transpiration: The process of water movement through a plant and its evaporation from aerial parts.
- Runoff: Water that moves across the ground and returns to bodies of water.
- Infiltration: The process by which water on the ground surface enters the soil.
