When water freezes, its molecules lose energy and get stuck in a lattice structure in which they are farther apart from each other than in their liquid state, thus making ice less dense than water
Particles do make objects denser than they normally may be. For example, if you add particles of salt to water, the water will become more dense. Alternately, if you filter impurities out of water it will become less dense.
Depending on the temperature, water drops that fall when the temperature is below freezing can become sleet, ice, or snow.
Water will freeze first, as sawdust does not have a freezing point. The freezing point of water is 0°C (32°F), while sawdust does not freeze but can become solid if mixed with water.
Different temperatures can affect water in several ways. When heated, water molecules move faster and expand, becoming less dense. Cold temperatures cause water molecules to slow down, making water denser. At 0°C, water freezes to become solid ice, while at 100°C, it boils and turns into a gas.
very slow downhill movement of rock and soil
Water expands when it freezes. Ice is lighter and denser than liquid water. Ice Floats! Most substances get denser when they turn from liquid to solid.
from the addition of salt
by the coldness of freezing and the warmness of thawing
It expends on freezing and its solid state (Ice) is less denser than liquid state (Water).
Water drops that fall when the temperature is below freezing and become solid are called snowflakes.

Density currents are caused by differences in water density. This can be due to variations in temperature, salinity, or both. When denser water sinks and interacts with lighter water, it creates a current that moves along the density gradient.

Freezing
yes
weathering
Liquids become solids upon freezing. Most solids contract when they freeze. The expansion of water when it becomes ice is an unusual property.
