Boy you ask long questions. To give you a rough idea though it works like this. Very small rain drops come down and a wind (up-draft) takes the drop up to a high freezing level, then it starts falling again, picks up more moister and get bigger, that another up-draft takes it up again and freezes it. This keeps on happening until the frozen raindrop is so big that it just keeps falling and hits the earth.

I hate to burst your bubble, but the process by which snow forms is
decidedly different than how hail forms. Snow forms by water droplets
freezing and crystalizing into hexagonal or linear forms and, although
buffeted about, remain frozen. Sleet is what occurs when the snow
crystals melt or partially melt before hitting the ground. On an
extremely cold day, you can actually create snow. If the temperature is
about 20 below 0 (F), if you take a pan of water and throw the water
into the air, the water will form ice crystals, or snow before it hits
the ground. I have seen this done, and I have done this myself. Hail
forms when water droplets freeze, and buffeted by the strong winds,
remain aloft as they travel through zones where water droplets are still
liquid. While traveling through these zones of liquid water droplets,
the surface tension of the liquid water causes the water droplet to coat
the surface of the ice particle. When the ice particle passes through a
zone where water freezes, the accreted water droplet freezes and becomes
part of ice particle. The ice particle will continue to grow until the
force of the updrafts can no longer support it's weight. Then it falls
to the ground as hail. In the south east quadrant of the continental US
where the squall lines create particularly strong storms, the hail
becomes quite large. Snow and hail are not the same thing. The only
thing that they have in common is that they are both frozen water. The
ice cubes in my freezer are also frozen water, but you could not call
them snow or hail either. If you are going to make a point of
something, at least try to make your physics correct.

As raindrops descend from a cloud, occasionally they will be caught in an updraft and carried high into the atmosphere where the temperature is far colder than at ground level. As a result, the droplets freeze. When this happens several times over, the droplets grow and grow, adding more ice every time, making them more and more heavy. Once the droplet is heavy enough to fall to the ground it is a hail stone.

Hail is formed when the water molecules are pushed back up into the cloud, over and over and over again, gathering more water as they do until they become too heavy(and frozen from the high altitudes) and fall to the ground and break car windows across the land.

as the rain falls, the cold temperature freezes it so its basically like frozen rain or ice...
i don't think it would be made of snow and rain because hail hurts
=/ lol

if it rains and the air cools,it freezes the rain and makes hail stones

All types are precipitation are "pure water", assuming evaporation took in full effect. It is devoid of salt, minerals, and some other ingredients most of the time.

it is a mixture of snow and rain. it happens when it is too warm to snow but too cold to rain.
