Which natural resource is primarily extracted from halite?

Halite is the mineral form of sodium chloride, commonly known as salt. It is primarily extracted for various uses, including culinary purposes, de-icing roads, and in some industrial applications. The formation of halite occurs through the evaporation of seawater or the evaporation of saline lakes, leading to the crystallization of salt.

In contrast, coal is a fossil fuel derived from organic matter and formed over millions of years, while gold is a precious metal typically mined from ore deposits using different methods. Marble, on the other hand, is a metamorphic rock composed mainly of calcite or dolomite, often used in construction and sculpture. Since halite directly corresponds to the extraction of salt, it is the correct answer.
