Sometimes, when ice crystals form in clouds and begin to fall, strong winds carry the ice crystals into the clouds. When the crystals begin falling again, they grow larger as more water droplets freeze onto them. Clumps of ice, called hailstones, start to form. Eventually, the hailstone grow too heavy for the wind to carry and they fall to Earth.




Describe a time during the formation of hailstones when the water relases energy.
