because it melt
Water changes into ice by solidification, aka freezing. When water changes into ice, the liquid particles are reorganizing themselves to become a solid particle.
The change that occurred to the water is a physical change. In this case, the water changed from a liquid state to a solid state without altering its chemical composition.
The process when snow or ice changes to water is called melting.
During the most recent ice age, which occurred around 20,000 years ago, large parts of Earth were covered in ice sheets and glaciers. Sea levels were much lower due to the amount of water locked up in ice, and there were changes in climate patterns and ecosystems. Human populations spread to different regions as they adapted to the changing environment.
When water is cold, it changes into ice, which is the solid form of water.
a physical change called melting. It is also called a phase change.

ice to water to ice
When ice changes to water, it is called melting. This process occurs when the temperature of the ice rises above its melting point, causing the solid ice to turn into liquid water.

The melting point and freezing point of water are physical properties. The melting point is the temperature at which ice (solid) changes to water (liquid), while the freezing point is the temperature at which water (liquid) changes to ice (solid).
