Hydrologic Cycle
The hydrologic cycle, or water cycle, is the continuous movement of water on, above, and below the Earth’s surface. It starts when water evaporates from oceans, rivers, and lakes due to heat from the sun. This water vapor cools and condenses to form clouds. Eventually, precipitation occurs as rain or snow, replenishing rivers, lakes, and groundwater. Water then flows back into the oceans, completing the cycle. This process is crucial for maintaining ecosystems, regulating climate, and providing fresh water for drinking and agriculture.

The hydrologic cycle, or water cycle, is the continuous movement of water on, above, and below the Earth's surface. It begins with evaporation, where water from oceans, lakes, and rivers turns into vapor and rises into the atmosphere. This vapor then cools and condenses to form clouds. Eventually, the water falls back to Earth as precipitation (rain, snow, etc.). The water then collects in bodies of water, infiltrates the ground, and is absorbed by plants. This cycle helps regulate climate, supports ecosystems, and is essential for all forms of life.
