GENERAL STATEMENT
Snow is water droplets that fall from
clouds. Then, those falling waters
becomes solid. You need to know that
rain consists of water vapor particles,
then cooled in the air.
They fell to the earth as pieces of soft,
white, and shaped like crystals. When
the air temperature has been hot, the
snow began to melt and disappear. It
turns directly into water vapor and the
process is called the sublime.
Sequences of process
To answer how the snow happens, we
can start from the water vapor in Earth's
atmosphere which are assembled. A
mass of water vapor cools to the point
of condensation (the temperature in
which a gas turns into a liquid or a solid
form), then those waters coagulate to
form clouds.
At the beginning, the mass of cloud
formation is much smaller than the mass
of air so that those can float in the air.
When you see, that’s just like the
wooden beams floating on the water
surface
However, after the steam increases and
merges inside the clouds, its mass also
increases, so that at some point the air
can no longer hold it. The clouds then
break up and the water particles fall to
Earth. The water particles that fall are
the pure one.
It means that the water does not
contaminated by the other particles.
Usually the air temperature below the
cloud is below the 0 degrees Celsius.
However, only a low temperature is not
enough to create the snow. When particles
of pure water are in contact with air, those
main parts are…
contaminated by the other
particles. There are certain
particles to accelerate the
freezing phase, so that pure
water quickly becomes
crystals of ice. Impurity
particles to function as an
accelerating phase of
clotting, it also becomes an
adhesive among the water
vapor.
So that, the water particles joined together with other water particles to form larger crystals. the air temperature does not melt the ice crystals, those will fall to the ground. Then, here's the snow! If the snow is not formed, the ice melts and gets to the ground in the form of rain water.
Closing
The rain process always begins with a snow
when it falls from the clouds, but then melts
when it crosses the heat temperature.
Sometimes, if the temperature is very low, the
ice crystals can form tiny balls of ice.
