Ice is the solid form of water, created when water is cooled below 0°C (32°F). It is a crystalline structure held together by hydrogen bonds, making it less dense than liquid water, which is why it floats. Ice plays a crucial role in Earth's climate, reflecting sunlight and influencing ocean currents. It exists in various forms, from glaciers and icebergs to frost and hail, and is used by humans for refrigeration, recreation, and scientific research.
