The term for water that has frozen into a solid state is "ice." Ice forms when water's temperature drops below its freezing point, typically 32°F (0°C) at standard atmospheric pressure. This transformation occurs as water molecules slow down and bond together in a crystalline structure, resulting in solid ice. Ice is a critical component of the Earth's ecosystem, impacting weather patterns, sea levels, and habitats for various wildlife. Additionally, ice can form in various contexts, including glaciers, snowflakes, and frost. It plays a significant role in outdoor sports, preservation of food, and even climate regulation.
