Editor's Notes
Student answers may include forms such as ice, sleet, snow, or hail or formations such as glaciers, icebergs, and ice caps. Most liquid water is found in oceans (which cover 71% of Earth’s surface). Water vapor is found in Earth’s atmosphere. Student answers may include forms such as ice, sleet, snow, or hail or formations such as glaciers, icebergs, and ice caps. Student answers may include a pond freezing over or water evaporating from a puddle.
