How Many Oceans Are On The Map

When we think of the world map, we often visualize the five oceans, which are the Atlantic, Pacific, Indian, Southern, and Arctic oceans. But have you ever wondered how many oceans are there on the map? In this article, we will explore and answer this question in detail.

What Defines an Ocean?

Before we dive into the number of oceans on the map, it's important to understand what defines an ocean. An ocean is a vast body of saltwater that covers more than 70% of the Earth's surface. They are typically divided by continents and ocean basins.

How Many Oceans Are on the Map?

There are currently five oceans on the map, as recognized by the International Hydrographic Organization (IHO). These oceans are:

1. Atlantic Ocean

The Atlantic Ocean is the second-largest ocean on the map, covering an area of approximately 106,400,000 square kilometers. It is bounded by North and South America to the west and Europe and Africa to the east.

2. Pacific Ocean

The Pacific Ocean is the largest ocean on the map, covering an area of approximately 168,723,000 square kilometers. It is bounded by Asia and Australia to the west and the Americas to the east.

3. Indian Ocean

The Indian Ocean is the third-largest ocean on the map, covering an area of approximately 73,556,000 square kilometers. It is bounded by Africa to the west, Asia to the north, Australia to the east, and the Southern Ocean to the south.

4. Southern Ocean

The Southern Ocean is the smallest ocean on the map, covering an area of approximately 20,327,000 square kilometers. It is located around the continent of Antarctica and is known for its strong currents and cold temperatures.

5. Arctic Ocean

The Arctic Ocean is the smallest and shallowest ocean on the map, covering an area of approximately 14,056,000 square kilometers. It is located around the North Pole and is known for its ice cover and polar bears.

Why Are There Five Oceans?

The five oceans on the map were defined by the IHO in 1953 to standardize the naming and mapping of the world's oceans. This organization recognized the Southern Ocean as a fifth ocean in 2000.

Are There Any Other Oceans on the Map?

While there are only five recognized oceans on the map, there are other bodies of water that are often referred to as oceans, such as the Mediterranean Sea, the Caribbean Sea, and the Gulf of Mexico. However, these are not technically considered oceans as they do not meet the criteria set by the IHO.

Conclusion

In conclusion, there are currently five recognized oceans on the map: Atlantic, Pacific, Indian, Southern, and Arctic. These oceans are vast bodies of saltwater that cover more than 70% of the Earth's surface. While there are other bodies of water that are often referred to as oceans, they do not meet the criteria set by the IHO.
