Hail is rain is the form of ice lumps that are usually round. Hail usually happens during storms, although not all storms bring hail with them. Hailstones can be up to 5 inches in diameter. The colder it is the larger the hailstones can become.
Hail is formed when rain drops within a cloud keep getting pushed up by strong winds. The rain drops get pushed to cold regions where they freeze and start to fall.
A hailstone can have several layers that can be seen if you cut one open. If you count the layers you can tell how many times the hailstone was blown back up into the cloud before it started to fall.
Hail is basically rain that had a hard time falling because of strong winds. The rain got blown into a cold area where it froze and started to fall. The more it got blown back into the cloud the more layers it formed therefore making it larger.
A hailstone can range in size from the size of a pea all the way to the size of a grapefruit.
I have learned that hailstones are a lot more complicated than falling ice chunks. There is a process that determines that size and the amount of layers they have. Although hailstones can become extremely large there has been barely any reported deaths caused by hailstones. The safest place during a hail storm is under a shelter.
