Describe the Water Cycle
it begins with evaporation, where the sun heats water from oceans, lakes, and rivers, turning it into water vapor. Plants also release water through transpiration. The vapor rises and cools, leading to condensation, where it forms clouds. When the droplets in clouds become heavy, they fall as precipitation (rain, snow, or hail). Some of this water flows into rivers and lakes (runoff), while some soaks into the ground as infiltration, replenishing groundwater. This collected water eventually returns to larger bodies.
