Answer: 71 percent
Oceans occupy 71% of the earth. About 71 percent of the surface of the Earth is covered by the ocean, a vast body of saltwater. Oceanographers and nations around the world have traditionally classified the planet’s ocean into four separate regions: the Pacific, Atlantic, Indian, and Arctic oceans. Oceanographers began designating the waters surrounding Antarctica as the Southern Ocean in the early 20th century, and National Geographic formally acknowledged this fifth ocean in 2021.
The oceans contain a whopping 97 percent of the world’s water. The weather, the temperature, and the availability of food for people and other animals are all significantly influenced by the ocean as a result. The ocean is still a mystery, in spite of its immense size and influence on every living thing on Earth. Humans have never charted, explored, or even seen more than 80% of the ocean. Compared to our own ocean floor, a much larger portion of the moon’s and Mars’ surfaces have been mapped and analyzed.
Due to the continental shelves, which are portions of the continents that extend far out into the ocean, making up a substantial portion of the bottom of the Atlantic Ocean, it is quite shallow. 3,720 meters is the average depth of the entire ocean (12,200 feet).
Some oceanographers think the number of species is decreasing as a result of the harm that pollution, rising sea temperatures, and other issues are causing to many marine ecosystems. However, oceanographers may be in for a lot more pleasant surprises in the years to come. Some scientists believe there are still between a few hundred thousand and a few million undiscovered species in the ocean, which means that more than 90% of the known species may still be undiscovered. There are currently about 226,000 ocean species known to science.
