Give two sheet reasons why cumulonimbus clouds are associated with snow and lightning

1. Cumulonimbus clouds are known for their towering height, which allows them to reach high into the atmosphere where temperatures are cold enough for snow to form.

2. The turbulent updrafts and downdrafts within cumulonimbus clouds create a dynamic environment that can lead to the formation of ice crystals and collision of ice particles, which are necessary for the development of lightning.
