 Evaporites such as Halite (mineral), gypsum and some limestones have been deposited from aqueous solution, mostly owing to evaporation in arid climates.Water-based ice in the form of snow, sea ice, and glaciers are common crystalline/polycrystalline structures on Earth and other planets.A single snowflake is a single crystal or a collection of crystals, while an ice cube is a polycrystal.
