Question

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

Explanation:

Hail forms in cumulonimbus clouds. Cumulonimbus clouds are tall, vertically developing clouds associated with thunderstorms, strong updrafts, and the conditions necessary for hail formation (supercooled water droplets freezing and being lifted repeatedly to grow into hailstones). Cirrus clouds are thin, wispy, high - altitude clouds and don't produce hail. Nimbostratus clouds are thick, gray, and produce continuous rain or snow, not hail. Stratus clouds are low - lying, uniform clouds that usually produce light precipitation like drizzle, not hail.

Answer:

cumulonimbus
