Answer
Salt can be separated from seawater using evaporation. This process involves heating the seawater to drive off the water as vapor, leaving the salt behind. Alternatively, distillation can also be used, where seawater is heated, and the steam is collected and condensed back into liquid, resulting in purified water and separated salt.
