Water Cycle Processes and Concepts

The video explains the water cycle, starting with the ocean, which covers 75% of Earth's surface. The sun heats the ocean, causing evaporation, where water turns from liquid to gas. This vapor rises and cools, leading to condensation and cloud formation. Precipitation occurs when water falls back to Earth as rain, snow, sleet, or hail. Some water becomes groundwater, absorbed by plants or accessed via wells. Plants also release water through transpiration. Water not absorbed becomes runoff, returning to the ocean, completing the cycle.
