Continents are very large pieces of land. Earth has seven continents. Asia is the biggest and Australia is the smallest. Listed in order of size they are: Asia, Africa, North America, South America, Antarctica, Europe and Australia/Oceania.
Scientists confirmed the existence of an eighth continent, called Zealandia, under New Zealand and the surrounding ocean in 2017. Because 94% of Zealandia's 2 million square miles are underwater, mapping the continent is challenging.
The 7 continents of the world are North America, South America, Antarctica, Europe, Asia, Africa, and Australia. The 5 oceans of the world are the Atlantic Ocean, the Indian Ocean, the Pacific Ocean, the Southern Ocean, and the Arctic Ocean.
Russia is a transcontinental country, a state which is situated on more than one continent. Russia spans the northern part of the Eurasian continent; 77% of Russia's area is in Asia, the western 23% of the country is located in Europe. European Russia occupies almost 40% of the total area of Europe.
The Seven Seas include the Arctic, North Atlantic, South Atlantic, North Pacific, South Pacific, Indian, and Southern oceans. The exact origin of the phrase 'Seven Seas' is uncertain, although there are references in ancient literature that date back thousands of years.
Historically, there are four named oceans: the Atlantic, Pacific, Indian, and Arctic. However, most countries - including the United States - now recognize the Southern (Antarctic) as the fifth ocean. The Pacific, Atlantic, and Indian are the most commonly known.
In terms of geography, seas are smaller than oceans and are usually located where the land and ocean meet. Typically, seas are partially enclosed by land. Seas are found on the margins of the ocean and are partially enclosed by land. Here, you can see that the Bering Sea is part of the Pacific Ocean.
The Pacific Ocean
The Pacific Ocean is the largest and deepest of the world ocean basins. Covering approximately 63 million square miles and containing more than half of the free water on Earth, the Pacific is by far the largest of the world's ocean basins. All of the world's continents could fit into the Pacific basin.

The Indian Ocean
The Indian Ocean has the warmest surface temperature of all the world¹s oceans, as most of it is found in the tropics.
The Arctic Ocean
The Arctic Ocean is the smallest, shallowest, and coldest part of the ocean.
The Weddell Sea has been claimed by scientists to have the clearest waters of any ocean in the world.
Of the five ocean basins, the Atlantic Ocean is the saltiest. On average, there is a distinct decrease of salinity near the equator and at both poles, although for different reasons. Near the equator, the tropics receive the most rain on a consistent basis.
the Atlantic Ocean
Covering approximately 20 percent of the Earth's surface, the Atlantic Ocean is the second largest ocean basin in the world, following only the Pacific. However, it is only slightly larger than half the size of the Pacific Ocean.
The United States is the third largest country in the world. It is in North America between the Atlantic and Pacific Oceans.
From smallest to largest they are the Arctic, the Southern, the Indian, the Atlantic, and the Pacific. The oceans in order from largest to smallest are the Pacific, Atlantic, Indian, and Arctic.
The Pacific Ocean was born 750 million years ago at the breakup of Rodinia, although it is generally called the Panthalassa until the breakup of Pangea, about 200 million years ago. The oldest Pacific Ocean floor is only around 180 Ma old, with older crust subducted by now.
Ocean salt primarily comes from rocks on land and openings in the seafloor. Salt in the ocean comes from two sources: runoff from the land and openings in the seafloor. Rocks on land are the major source of salts dissolved in seawater. Rainwater that falls on land is slightly acidic, so it erodes rocks.
Pangea, also spelled Pangaea, in early geologic time, a supercontinent that incorporated almost all the landmasses on Earth. Pangea was surrounded by a global ocean called Panthalassa, and it was fully assembled by the Early Permian Epoch (some 299 million to about 273 million years ago).
The Pacific Ocean is the oldest ocean in the world with the oldest part of it's floor dating to around 180 million years. However, the Pacific Ocean is technically much older as it developed from the center of Panthalassa, an ancient ocean that first began forming around 750 million years ago.
