Summary of The Water Cycle Explained
The video explains the water cycle, also known as the hydrological cycle, which describes the continuous movement and recycling of water between the atmosphere, land, and sea. Key processes and concepts involved in the water cycle include:
- precipitation: Water vapor in the atmosphere falls to the ground as various forms of precipitation, primarily rain, but also snow, sleet, and hail.
- Storage on Land: Precipitated water can be stored as:
- glacial ice
- Surface runoff
- freshwater in lakes
- Groundwater (through percolation in porous rocks or soil)
- Runoff: Water that flows over the land eventually reaches rivers and streams, leading to the sea.
- transpiration: Plants absorb water and release water vapor back into the atmosphere, accounting for about 10% of water returned.
- evaporation: Approximately 90% of water vapor returns to the atmosphere through evaporation, driven by solar radiation transforming liquid water into gas.
- Evapotranspiration: The combined process of evaporation and transpiration.
- Condensation: As water vapor rises and cools in the atmosphere, it condenses into liquid water, forming clouds.
The cycle then repeats itself continuously.
