4. Which Ocean is Very Smallest?

Out of all the oceans, which is the largest and smallest oceans? The smallest is the Arctic Ocean. It is of 14 million sq kilometers total area. The Canadian basin is the deepest part. The National Oceanic and Atmospheric Administration determine the ocean’s average depth to be 2.3 miles. (See What is the Water Cycle in Order?)

The second largest ocean is the Atlantic Ocean which extends along the United States East Coast. 21% of the Earth’s surface is covered by this ocean. The coastline is Africa, America, and Europe; whereas Puerto Rico Trench is the deepest known place. Moreover, the world’s largest drainage area is the Atlantic Ocean. It is responsible for maintaining a sustainable global temperature by carrying cool water across the planet’s surface. The global ocean conveyor is driven by the North Atlantic.

6. What is the Second Smallest Ocean?

The Southern Ocean is the second smallest ocean at 21,960,000 sq km. It is roughly 7 times smaller than the Pacific Ocean, the largest ocean. Antarctica is surrounded by the Southern Ocean at the globe’s bottom. It has a depth of 3–70 m. A diverse collection of whales, penguins, and other wildlife species have been found here but are at risk due to climate change, threats, and pollution.

  • The Sargasso Sea, with an area of 3.5 million square km, is the second largest sea and is part of the Atlantic Ocean. Christopher Columbus discovered the sea. Algae and plankton are found in abundance, and winds are frequently absent.
  • The South China Sea, with an area of 3.5 million km square, is the third largest sea and is also part of the Pacific Ocean. About 200 islands are in the sea, and the sea bathes some coasts like China, Malaysia, and Indonesia.

The youngest ocean on the planet is the Atlantic Ocean. It is second on the list of which is the largest and smallest oceans. It is the world’s second-largest ocean, with an area of about 106,400,000 square kilometers. Being the Atlantic is the youngest ocean, it covers 20% of the Earth’s surface covered by the ocean. It is surrounded by America on one side and Europe and Africa on the other side. (See What is the Oldest River in the World?)

13. Which Ocean is Coldest?

The coldest ocean is the Arctic Ocean and also the world’s smallest ocean. It is the least salty ocean. It has polar ice because of its location on the North Pole. Cold temperatures support very little plant life but diverse species of fish.
