Question

from which type of clouds do hail pellets form?
cirrus
cumulonimbus
nimbostratus
stratus

Explanation:

Cumulonimbus clouds are associated with thunderstorms. They have strong updrafts. In these clouds, water droplets are carried high up where they freeze. These frozen droplets (hail pellets) grow as more water freezes around them. Cirrus clouds are high - level, thin clouds and not associated with hail. Nimbostratus clouds are associated with continuous rain, not hail. Stratus clouds are low - level, usually associated with light rain or drizzle.

Answer:

cumulonimbus
