Which are the natural sources of water?

Have you ever wondered which are the natural sources of water? Here is the answer. Natural sources of water are oceans, rivers and lakes. Here are a few pieces of information you should really know about each of them:

Oceans

Oceans can be described as being a vast body of salt water, oceans cover about 70% of the earth's surface.

One way to obtain drinking water from salt water
is distillation, this is one of the oldest treatment and still popular today.

This source of natural water also provides us other resources like: food (sea food and fish), oil, salt, minerals, metals and of course means of transport.
Also it is well known that oceans influence climate.

Rivers

Rivers are natural streams of water flowing flowing towards an ocean, a sea,  a lake or another river. 

There are about 165 major rivers in the whole world, first ones are the Amazon, the Nile and the Yangtze. Other than these major rivers there are thousands of smaller which also act as a source of natural water for billions of people.

Lakes

One can define a lake as a large area of water which is surrounded by land. Of course there might be a river which can serve as feed or drain for the lake.

Lakes supply drinking water, generate electricity, can be used to irrigate fields and of course it can serve as recreational areas.

You should know that drinking water from a lake is not healthy and you should disinfect the water before drinking it. By drinking from this source of water you risk getting waterborne diseases. A natural way of purify lake water for drinking is boiling it.
