Sea Water: An Overview

The water of the oceans, which is called seawater, is salt water. It is a complex mixture of 96.5% water, 2.5 per cent salts, and small amounts of other substances.  Salts, primarily the chemical compound sodium chloride (NaCl), dissolve in water (The salt that people eat is sodium chloride in crystal form.)

Do you know we use seawater in our daily activities? Seawater is a major source of food, minerals, and other raw materials.  We get salt, fish and other marine products, seaweed, mineral oil, and other minerals from the oceans. Medicines and beauty products are also sourced from the oceans. We also get aquaculture supplements to increase food production. These show how we use seawater in daily life. There are various uses of Seawater that we don't know. In this article, we are gonna discuss the unimaginable healing powers of Seawater.

What is the Importance of Sea Water?

  • The water that covers much of our planet helps to make up the air we breathe.  The millions of tiny plants that live in the Seawater produce the precious oxygen we breathe.

  • Oceans connect the continents, providing a cheap and easy option for transportation.

  • Seawater plays an important role in controlling the weather and climate.  Apart from precipitation, the atmosphere receives most of its heat from the oceans. The Sun heats the seawater, and they, in turn, transfer the heat to the atmosphere.  The atmosphere then distributes the heat around the world.

  • Seawater in the Gulf is used in Canada and France to generate electricity using tidal energy.

  • Beaches around the seawater are also means of refreshment.

  • Coastal winds are full of moisture, so areas near the sea receive a lot of rainfall while those located far away generally receive less rainfall.
