Question

Salt is obtained from sea water by drying it in the sun. This process is known as ______.

• A. filtration
• B. evaporation
• C. sedimentation
• D. condensation

Answer 1

The correct option is B evaporation

Evaporation is type of vaporization that occurs on the surface of a liquid as it changes into gas.
Sea water contains a large amount of salt and other metals dissolved in it. Near the sea-shore, the sea water is collected in shallow pits and allowed to evaporate in sunlight. In few days, the water evaporates, leaving behind salt.
