Study Notes
The Water Cycle
- The water cycle is the continuous recycling of water on earth, from the oceans to the sky and back to land, and then transported back to the oceans and sky again.
- The water cycle is driven by the energy of the sun, which transforms surface water into water vapor.
The Three States of Water
- Solid: ice
- Liquid: wet and fluid
- Gas: water vapor in the air
The Four Processes of the Water Cycle
- Transpiration/Evaporation: the sun heats up water in seas, rivers, lakes, oceans, and glaciers, turning it into water vapor or steam, which rises into the atmosphere; plants and soil also release water vapor through transpiration.
- Condensation: water vapor cools and condenses, changing from gas to liquid (water droplets), forming clouds.
- Precipitation: when clouds become too heavy with water, the water falls back to the earth; if the atmosphere is cold enough, precipitation can take the form of snow or sleet.
- Collection/Water Storage: water returns to bodies of water, such as oceans, seas, rivers, lakes, and glaciers, or is absorbed into the soil through infiltration.
