Explain how ice crystals grow in a cloud. Under what
conditions will ice crystals fall as snow? Under what
conditions will the ice crystals form hail?
Upper layers of clouds contain ice crystals and
super-cooled droplets. As super-cooled droplets
evaporate, the water vapor is deposited on ice
crystals. Heavy crystals fall, clumping together to
form snow.
If the snow doesn’t fall through a layer of warm air
that melts it into rain, it may reach the ground as
snow .
Hail forms when a growing ice crystal is kept aloft by
updrafts and continues to grow into a large ice
clump. Bonus points: As the hail is carried up it then
refreezes adding to its diameter. Bonus: Show a
drawing depicting this concept.
Essay #1
What types of clouds will form when a body of
warm, moist air rises to a region of dry, stable
air? Explain why and how they form.
Cumulus clouds will form.
Cumulus clouds grow vertically.
Warm air rises and cools, causing condensation.
Clouds grow upward until temperature and density
of inside of cloud is same as outside air.
