“Ice floats on water because:”

"Ice floats on water due to its lower density compared to liquid water. When water freezes its molecules form a crystalline structure with more open space reducing density. This property allows ice to displace enough water to float a phenomenon critical to aquatic ecosystems. In colder climates floating ice insulates water bodies preserving aquatic life. This unique characteristic of water rooted in its molecular structure underscores its significance in environmental science and natural processes."
