Separation techniques are used to separate mixtures into its constituent elements and/or compounds. Recall that a mixture contains elements and/or compounds which are not chemically combined together.
By separating the constituents of the mixtures, we are able to find out the properties of the known/unknown substances from mixtures and possibly use them for the production of useful substances such as medicines.
Depending on the physical and chemical properties of the substances in the mixture, we can choose the most appropriate separation technique to isolate them from the mixture.
Water cycle involves the movement of water from the lakes or rivers then it evaporates due to sunlight forms clouds, condenses and falls back as rain giving clean water
