Question

what is the primary method used to produce salts from seawater? solar evaporation filtration distillation crystallization

Explanation:

Seawater is allowed to evaporate using solar heat. As water evaporates, salts are left behind. This is the most common and traditional way to produce salts from seawater. Filtration is for removing solids, distillation is mainly for separating liquids based on boiling - points, and crystallization usually requires more controlled conditions compared to the large - scale solar evaporation of seawater for salt production.

Answer:

Solar evaporation
