top 5 largest oceans and Seas in the world

1. Pacific Ocean

The Pacific Ocean is the largest ocean in the world

Area: 63,800,000 square miles (165,250,000 square kilometers)

Sea Area %: 46.40

Average Depth (m): 4.280

Greatest Depth (m): Mariana Trench, 10,900

Pacific Ocean

The Pacific Ocean is the largest body of water in the world. The Pacific Ocean is the largest ocean in the world, covering about 28% of the land area and nearly twice the water area. It touches the west coast of North America. It is also home to the world's deepest trench, the Mariana Trench, which houses the Challenger Deep. It is 10,900 feet deep, much deeper than the height of Mount Everest. The graben sits between two tectonic plates, which accounts for its incredible depth. The ocean coasts along North America and Japan are prone to earthquakes.
ocean was named by explorer Ferdinand Magellan. As a "peaceful sea" he chose the "Pacific". The Pacific Ocean is home to the Ring of Fire, a U-shaped chain of 450 volcanoes stretching from South America along the coast of Japan to the western United States and New Zealand.

1. 2.Atlantic Ocean 

The Atlantic Ocean covers around 20% of the Earth’surface

Area: 41,105,000 square miles (106,460,000 square kilometers)

Sea Area %: 22.90

Average Depth (m): 3.926

Greatest Depth (m): Puerto Rico Trench. 9.219

Atlantic Ocean

The Atlantic Ocean is the second largest ocean in the world after the Pacific Ocean. The ocean covers about 20% of the earth's surface and is believed to have formed in the Jurassic period. It is also connected to the Pacific, Arctic, Indian, and Southern Oceans. The equator divides the ocean into two parts, the North Atlantic and the South Atlantic.
Ocean is home to a variety of marine life, such as turtles and dolphins, and creatures that live more than 3,000 feet below the surface. Interestingly, the world's largest island, Greenland, lies between the Atlantic and Arctic Oceans.

1   3.Indian Ocean 

The Indian Ocean is the warmest Ocean in the world.

Area: 27,240,000 square miles (70,560,000 square kilometers)

Sea Area %: 20.45

Average Depth (m): 3.963

Greatest Depth (m):  Java Trench 8,047

Indian Ocean

The Indian Ocean is the third largest ocean. It covers about 1/5 of the Earth's surface and includes many tropical islands. The ocean is bordered by Africa to the northwest, Antarctica to the south, India and Asia to the north, and Australia to the east. Includes the Arabian Sea and the Laccadive Sea. The Indian Ocean is the 3rd-largest ocean in the world.

1.      4. Antarctic Ocean (Southern Ocean)

The Antarctic Ocean is very large and deep.

Area: : 7,849,000 square miles (20,328,816 square kilometers) 

Sea Area %: 6.06

Average Depth (m): 3.456

Greatest Depth (m):  South Sandwich Trench. 7.236

Antarctic Ocean

The Antarctic Ocean is  also called the Southern Ocean . Antarctic Ocean is the fourth largest ocean in the world. Scientists constantly argue about its limitations. Some don't see the sea at all. The famous James Cook circumnavigated the Southern Ocean in 1770 and demonstrated that southern latitudes could be circumnavigated in its waters. Its ecosystem has changed rapidly in recent years due to climate change.

1.   5.Arctic Ocean

The Arctic Ocean is the world’s smallest and shallowest ocean.

Area: 5,427,000 square miles (14,055,865 square kilometers) 

Sea Area %: 4.19

Average Depth (m): 1.205

        Greatest Depth (m):  Arctic Basin. 5.441

Arctic Ocean

       The Arctic Ocean is both the coldest and the saltiest. It covers the North Pole and is considered the coldest of all oceans with the lowest salinity. Scientists must dive through the ice into the dark waters of the ocean. Sea ice has shrunk every year since measurements began in 1979. The ocean is usually covered in sea ice
