Water can evaporate at any temperature because not all water molecules have the same speed (kinetic energy).What Is Evaporation?Evaporation is the process by which a liquid turns into a gas.

Oceans and seas are salty because they contain large amounts of salt (mineral-based substances).

Minerals within the rocks (natural stone materials) dissolve and mix with the
