๐ Topic Summary
The water cycle, also known as the hydrologic cycle, describes the continuous movement of water on, above, and below the surface of the Earth. It's a crucial process that sustains life and shapes our planet's climate. The cycle includes key processes like evaporation (water turning into vapor), condensation (vapor turning into liquid), precipitation (water falling back to Earth), and collection (water gathering in bodies of water). Understanding this cycle is essential for grasping how water resources are distributed and managed. ๐ง
