The oceans, which cover 71% of the Earth’s surface, are home to diverse living and nonliving beings. These include plants and animals that make up the food web and a variety of other organisms. Oceans have a huge impact on human life in many ways, like by providing fish for eating and other sources of protein. They also provide habitats for marine life, which can help to regulate populations of other organisms.

Let’s explore the 5 Oceans of the world:

Atlantic Ocean

The Atlantic Ocean is part of the world’s major oceans that surround most of the Earth. It is also one of the few seas which are free from ice. The Atlantic Ocean covers an area of roughly 14.3 million km2 and its average depth is approximately 3,780 meters deep. The first recorded mention of this ocean was by Pytheas in 325 BC.

Pacific Ocean

Pacific Ocean is one of the seven largest oceanic divisions, occupying about 30% of the Earth’s surface. It is also the world’s largest ocean. Pacific Ocean is one of the seven largest oceanic divisions, occupying about 30% of the Earth’s surface. It is also the world’s largest ocean. The Pacific Ocean was called by its ancient Greek name “Oceanus Procellarum” from about 8th century BC until 2nd century AD when it was renamed by Pomponius Mela after his map on which he explored and described this region as Mare Pacificum (Latin for “Pacific Sea”). The Pacific Ocean surrounds Australia, New Zealand, Indonesia, Japan, China and many other countries in an almost circular pattern. The International Hydrographic Organization (

Indian Ocean

The Indian Ocean is the third largest of all the Earth’s oceanic divisions. It is bounded on the north by India, on the west by east Africa, and on the east by southeast Asia. The Indian Ocean is a body of water that separates the continent of Asia from Australia and Africa. This vast body of salt water stretches from East to West and covers an area measuring about 20% of Earth’s total surface area. The Indian Ocean has many islands including Madagascar and Sri Lanka in its waters. The Indian Ocean is also known as “the ocean of milk” due to its abundant supply of seafood in that region. It is full with tuna, salmon, shrimp, tuna fish, crab meat, lobster crustaceans and mackerels among other fish species.

Southern Ocean

The Southern Ocean is the third largest ocean on Earth. It is located south of the Equator between 30 and 60 degrees south latitude. It covers approximately 14 million square kilometers, making it nearly as large as all other oceans combined. Due to the remoteness of this part of the world, it has been observed that marine life diversity is higher in this area than in any other ocean. The Antarctic continent has about 10 thousand species while there are some 3 million species living around Antarctica’s coastlines. The Southern Ocean experiences a continuous stream of icebergs that have been drifting from Antarctica for centuries due to warming effects at the poles and also from volcanic eruptions on land. These icebergs add to its enormous size, which makes it difficult for shipping companies to navigate through without getting lost from

Arctic Ocean

The Arctic Ocean is the world’s largest ocean, covering more than 15 million square kilometers. It contains almost 20% of the world’s fresh water and is home to more than 15,000 species of animals and plants. The Arctic Ocean is a natural resource that provides valuable ecosystem services for the benefit of humanity. The Arctic Ocean has recently been experiencing rapid changes due to climate change and industrial activities such as fishing, shipping, mining, drilling activities. As it continues to warm in response to human emissions of greenhouse gases, sea ice has declined at an accelerating rate and in 2012 became the first ocean to have less than one million square kilometers of ice coverage.
