TITLE
Photography is a way scientists can investigate the water cycle. Snowflakes are beautiful and unique. The way they look can explain how snowstorms work and the relationship between flake and cloud.
Evaporation is different from boiling water on a stove. Evaporation happens mostly at the surface of a liquid. When water boils, droplets are becoming gas all throughout the liquid. Boiling requires more heat than evaporation. Water begins to boil once it reaches 212 degrees Fahrenheit (100°C).
