Answer:
Ice hailstone.
Step-by-step explanation:
Precipitation can occur in two types of forms. The first consists of liquid water, which does not acquire much speed when falling, so it does not cause harm to fall on a person. The second is solid water, which can vary in size from a grain to small balls. Being in this state acquires greater speed and if it hits a person can cause great damage because it does not fade easily.
Have a nice day!
