hail
Water droplets turn into snow when the temperature is cold enough for them to freeze. As the droplets freeze, they form ice crystals which then accumulate to form snowflakes. Snowflakes can continue to grow in size as they fall through the atmosphere before reaching the ground.
The question needs a better focus. Taking it as read, the pieces become impacted. Or perhaps a bimetallic strip? Or a sedimentary rock?
The pull on the surface of liquids that allow liquids to form drops when they fall are called surface tension. This property is due to the cohesive forces between liquid molecules at the surface.
Those drops of water are called dew. Dew forms when the temperature of the surface cools down and reaches the dew point, causing water vapor in the air to condense and form small droplets.
If they freeze on the way to hitting the earths surface, they are called sleet. You can tell the difference between hail (which freezes before it leaves the cloud) is that sleet bounces when it hits the ground. You are talking about weather, right?
Cloud drops
eerm no freeze it a form of freezing in context with coldness hence being called freezing.
The breaking down of rocks into smaller pieces is called weathering. Weathering can be physical, through processes like freeze-thaw cycles or root wedging, or chemical, involving the dissolution of minerals in water or oxidation. The resulting smaller pieces, called sediments, can then be transported and deposited by various agents such as water, wind, or ice to form sedimentary rocks.
If you mean acidic rain, then rain drops obviously form chemical weathering. Weathering is the breaking down of rock into smaller pieces. Erosion is the carrying of sediment by water, wind, or ice.
These are called dew drops. They form when the temperature of the surface cools down causing water vapor in the air to condense and form small droplets of water. Dew is more likely to form on clear, calm nights when the temperature drops close to the dew point temperature.
Puddles freeze when the temperature drops below freezing, causing the water molecules to slow down and eventually form ice crystals. This process happens because cold temperatures freeze the water, turning it from a liquid to a solid state.

When wind drops its load of sand, it can form a hill called a sand dune. Sand dunes are commonly found in deserts and coastal areas, and their formation is a result of the movement and deposition of sand by wind.
Weathered pieces of rock are called sediment. As rocks are broken down by physical or chemical processes, they form sediment that can be transported and eventually deposited elsewhere.
