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.
