Salt is obtained from seawater by which process?

Evaporation

The correct answer is option 3. Evaporation.

Salt is obtained from seawater through the process of evaporation.

During evaporation, seawater is collected in large shallow ponds called salt pans or salt evaporation ponds. These ponds are exposed to the sun and wind, allowing the water to evaporate over time, leaving behind salt crystals. The remaining salt is then harvested, processed, and purified for various uses, including culinary, industrial, and chemical applications.
