What are some different properties between chalk and snow?

Chalk and snow differ significantly in composition and properties. Chalk is a sedimentary rock primarily composed of calcium carbonate, giving it a hard, porous texture and a typically white color. In contrast, snow consists of frozen water crystals, which are soft, fluffy, and can vary in structure depending on temperature and humidity. While chalk is stable and can endure physical stress, snow is transient and changes rapidly with temperature fluctuations.
