On Earth, water can regularly be found in three different phases—liquid, solid, and gas—each of which has noticeably different properties. For example, a boat can glide through liquid water in summer, but it cannot do so when the water turns to solid ice in winter. Atmospheric conditions, specifically seasonal temperatures, can influence the phase in which water exists at a given time. This short video segment, produced for Teachers' Domain, depicts water in different seasons at the same location.
