The planet Earth is a planet of oceans. The total area of the Earth is approximately510 million square kilometers and the oceans cover about 71 percent of theEarth's surface, which is about 360 million square kilometers.
There are a total of 5 oceans, and they are the Arctic, Pacific, Atlantic,Indian, and the Antarctic Ocean. Out of these five, there are three major oceans,the Atlantic, Pacific, and the Indian Ocean. They account for 90 percentof the area covered by oceans. The Pacific Ocean is the largest of oceans, itsarea is 181 million square kilometers, which covers nearly a third of the Earth'ssurface. The Atlantic Ocean is the second largest, covering 94 million squarekilometers, and the Indian Ocean is the third largest, covering about 74 millionsquare kilometers.
The oceans' tremendous presence causes it to have a huge effect on the planetand our civilization. It is greatly responsible for the climate of the Earth.It regulates air temperature and supplies moisture for rainfall. The ocean alsoprovides us with food, energy, minerals, and a cheap method of transportation.Without the oceans, the Earth wouldn't be able to sustain life.
