Question

Which if the following is NOT necessary for hail formation

O Strong updrafts
O Cumulonimbus clouds
O Very cold air at the surface
O Unstable air

Answer 1

Hail formation requires strong updrafts, cumulonimbus clouds, and an unstable air mass, but very cold air at the surface is not necessary.

Step-by-step explanation:

Hail formation requires certain conditions to occur. These include strong updrafts inside cumulonimbus clouds, very cold air at the surface, and an unstable air mass. However, very cold air at the surface is not necessary for hail formation. While it can contribute to the process, hail can still form in moderately cold temperatures.
