When ice melts, it changes from a solid state to a liquid state. This process occurs when the temperature rises above the freezing point of water, which is 0 degrees Celsius (32 degrees Fahrenheit). As the temperature increases, the molecules in the ice gain energy and begin to move more freely, breaking the bonds that hold them in a solid structure. The melting of ice is a common occurrence in nature, especially during warmer months. It plays a crucial role in the water cycle, contributing to the flow of rivers and lakes. Additionally, melting ice from glaciers and polar regions, such as the Arctic and Antarctic, is a significant concern in discussions about climate change.
