• Water exists in three states: liquid (used for drinking, cooking, and cleaning), solid (ice, found in polar regions and glaciers), and gas (water vapor in the atmosphere).
• The Water Cycle is a continuous process where water evaporates, forms clouds, and falls back to Earth as precipitation, sustaining life on the planet.
