Evaporation and Distillation are the two methods that are widely used to obtain pure water from seawater.

Explanation:

• We can obtain pure water from seawater in many different ways.
• There are ways through which the water is obtained in its pure sense without any salt content.
• Evaporation refers to the conversion of a liquid into the form of gas.
• It converts the water present in the container in the form of vapors on heating and the only substance left behind is the salt.
