Why hailstones melt on its way to the ground?

Open in App

Solution

Hail begin to melt rapidly once they fall into the low levels of the atmosphere where temperatures are above freezing. It is like putting a blow drier to the ice. ... Most of the mass of ice and hailstones reach the ground in the form of rain.
