There are five oceans in the world: Pacific Ocean (the largest), Atlantic Ocean (the second-largest), Indian Ocean (Antarctica), Southern Ocean (Antarctica), Arctic Ocean (the smallest. Most of the oceans are made up of salty water. They cover 70% of the Earth's surface, and 97% of its water. You should note that freshwater is only a small portion of the water available on Earth. Freshwater is essential for human survival, as well as most animals and plants. Some parts of the world have problems with salinization. Many aquatic species live in the oceans.
There are many theories about how the oceans formed. The volcanic outgassing theory is supported by most earth scientists. One theory states that water vapor from volcanoes millions years ago condensed to form the oceans we see today.
More than 30% of the Earth's total surface is covered by the Pacific Ocean. The Latin word Pacificus, which means peaceful in Latin, gave rise to the name Pacific Ocean. According to its name, the Pacific Ocean is peaceful. But the Pacific Ocean isn't peaceful and tranquil. The "Ring of Fire" is located in the Pacific Ocean. The Pacific Basin is home to many active volcanoes. Here are found some of the strongest earthquakes and volcanic eruptions anywhere in the world. Challenger Deep is the lowest known point on Earth. It is located at 10,920 metres at the Mariana Trench, near Guam.
One-fifth the Earth's surface is covered by the Atlantic Ocean, a body of seawater. It divides the continents Europe, Africa and North America to one side from the continents South America and North America the other. Its name, "Sea of Atlas", comes from Greek mythology. It is second in size to the Pacific Ocean.
The Atlantic Ocean generally follows a S-shaped shape. It is also very short. The Atlantic Ocean, without its dependent seas covers approximately 31,568,000 sq miles (81,760,000 km). Its area is 32,870,000 sq. miles (85,133,000km). It is an average depth of 11,962 feet (3.646 metres), and it reaches its highest depth at 27,493 feet (8.380 metres) in Puerto Rico Trench.
The Indian Ocean is the largest of the five oceanic divisions. It is 70,560,000km2 (27.240,000 sq mi, or 19.8%). It is bordered on the north and west by Asia, Africa and Australia. It is bordered to the south by Antarctica or the Southern Ocean.
The Southern Ocean (also known as the Antarctic Ocean) is the most southern ocean on the planet. It is located south of Antarctica at 60 degrees S. It is the second-smallest oceanic division. Although smaller than the Pacific, Atlantic and Indian Oceans, it is larger than the Arctic Ocean. Over the past 30 year, the Southern Ocean has seen rapid climate change. This has caused changes in the marine ecosystem.
