The shapes of the snowflakes keep changing until spring arrives, and the snow becomes water once again. Activities Catch snowflakes using laminated black paper. Use a magnifying glass to look at differences. Sketch a picture. Try catching snowflakes during different kinds of weather a mild day, a cold day, a windy day.
Snow falls on only one-third of the Earth every year.
In polar areas, snow falls all year long, but in tropical areas it snows only at the summit of very high mountains. In temperate areas, snow usually falls only in the winter. Cirrus clouds are cold clouds that are high above the ground and made of ice crystals and snowflakes. Even places which don t get snow get cirrus clouds. Most of the world s glacier ice is found in the huge ice sheets of Antarctica and Greenland.
