Did you know that fresh water contains salt also but not enough to be noticeable. If you were taking a glass of water and add a pinch of salt, it might still taste fresh or seems salty depending on your taste. However, if you add a teaspoon of salt to a glass of water virtually it’s become salty to drink. That is almost the same proportion of water and salt as in the ocean. In fact ocean water is about 220 times saltier than fresh water in a lake. To give you an idea of how much salt this is, if all of the salt in the oceans were removed and spread over all the earth’s land, it would form a layer about as high as a 40-story building. The Red Sea and Persian Gulf are very salty because of the evaporation is too high. The Sargasso Sea in the North Atlantic is also very salty because the water temperature is high and it is too far from land to receive an influx of fresh water. And also other same parts of the ocean are hardly salty at all.
