The ocean is a major component of the Earth’s life support system, driving water, air, and nutrient circulation; regulating temperature; controlling surface weather and climate patterns; absorbing carbon dioxide from atmosphere.
The ocean includes both salt water and fresh water. The salinity of an ocean varies with the amount of dissolved salts in it. A solution with a higher salinity has more salt ions per liter than a lower-salinity solution, so that low-salinity oceans have correspondingly lower densities.
The bulk of the ocean is deep below sea level where pressure causes water to come out of solution (as ice) to form ice shelves and glaciers.
While the word “Ocean” brings to mind an enormous body of water, it also holds a lot more.
An ocean is a large body of salt water that covers more than 70% of the Earth’s surface and contains 97% of all the Earth’s water. There are four major oceans on our planet: Atlantic Ocean, Indian Ocean, Pacific Ocean, and Arctic Ocean.
All Oceans are interconnected and are constantly exchanging water through currents. The flow in these currents plays a vital role in shaping the climate and weather in different parts of the world.
The ocean is the world’s largest ecosystem. It contains 97% of the Earth’s water, and its cycle is integral to life on our planet.
