Isnt’t it fun to be at the beach on a hot day? Making Sand castles, getting wet by the waves, salty ocean water filling up your mouth while you’re taking a dip. But have you ever wondered why the ocean water is salty ? How did it become this way?

What happens is,that,when a river flows into the ocean it carries some land with it. This land is made up of rocks and soil, which contains minerals. One of these minerals is Salt.

You cant taste the salt in the river because rivers don’t carry enough amount of salt at any one time. You can also not taste it in the lakes because one river brings the salt in and the other river flows it out.

Salt water is not good for humans or plants. Scientists are working on machines that will pull out the salt from the sea water. Wouldn’t it be great if we can make all this sea water non-salty? That will be a great gift to humanity as we will have so much more water for us.

Is it true that if you pour a handful of salt into a full glass of water, the water level will actually go down rather than overflowing the glass?
