Study Notes
The Water Cycle
- The water cycle, also known as the hydrologic cycle, describes the movement of water on, above, and below Earth's surface.
- Water constantly changes states (solid ice, liquid water, gaseous water vapor) within the cycle.
- The hydrosphere encompasses all Earth's water in all states near its surface. It includes surface water (rivers, lakes, oceans), groundwater, and atmospheric water vapor.
- Earth's water supply is finite; no new water is created; it's recycled.
Main Parts of the Water Cycle
- Evaporation: Liquid water is heated, turning into water vapor. The sun is the primary heat source.
- Condensation: Water vapor cools and changes back into a liquid. This can happen due to saturation (the air cannot hold any more vapor) or cooling (vapor reaching its dew point).
- Precipitation: Water returns to Earth's surface as rain, snow, sleet, or hail.
Additional Processes in the Water Cycle
- Sublimation: Direct transition from ice to water vapor (skipping the liquid phase). Important in snow's contribution to the atmosphere.
- Transpiration: Evaporation of water from plant leaves.
- Runoff: Water flows over the land's surface due to gravity.
- Infiltration: Water soaks into the ground, replenishing groundwater.
Importance of the Water Cycle
- Crucial for life on Earth because it sustains all life forms.
- Accounts for roughly 1% of readily available water on Earth.
- Closely linked to Earth's climate, influencing weather patterns, ecosystems, and geography.
