Explanation:

Hail is a form of precipitation when droplets of water freeze together in the cold upper reaches of the thunderstorms.  Thee chunks of that range from 5 to 15 cm can be round and jagged. Hail fall on the ground in a solid form they are often associated with tornadoes and certain parts of the world receive more hail than other parts do. These frozen droplets of water when fall from the clouds get uplifted by wind and that adds another layer to them. The freezing occurs below the zero degrees at an altitude of 11,000 feet. Mostly found in North America Nebraska, colorado and Wyoming states. and African regions in winter and South America in summer. Varies in diameter from peas shape to size of a softball.
