What Are Clouds Made Of?
5. Hail
Hail is also water that has been frozen. Only this time it freezes into solid balls of ice rather than lighter, fluffier snowflakes. Hail is usually formed by powerful thunderstorms and it is thought that hailstones grow by being taken up into the clouds by an updraft and then accumulating more water as they descend again.
If you do suspect hail is on its way then it is a very good idea to get indoors as soon as you can. Hailstones are denser and harder the snow and will fall rather quickly. Hard lumps of falling ice can be painful and they can even be dangerous when large enough.
