How many oceans on the globe
How many oceans on the globe
The planet Earth could well be called Ocean,because a considerable part of its surface is occupied by vast water spaces. Ocean depths conceal in themselves untold riches, which include not only the plant and animal life, but also valuable fossil resources. But so far scientists have not come to a consensus as to how many oceans are located on the planet.
Oceans on the Earth's surface
Oceans call the largest waterspace, which constitute the bulk of the world's water resources. These objects are located between the continents, possessing their own system of currents and other features. Each ocean continuously interacts with land, the earth's crust and the atmosphere. A special science, called oceanology, is studying these waters. The global reserves of salt water contained in the oceans constitute a significant part of the hydrosphere. The ocean waters are not a continuous shell, which is washing the planet. They surround different parts of the land - continents, archipelagos and individual islands. All the terrestrial ocean waters are divided into parts taking into account the mutual location of the continents. Separate parts of the oceans form seas, straits and bays.How many on the planet of the oceans
At present, most specialiststend to allocate five oceans on the Earth: Indian, Pacific, Atlantic, Arctic and Southern. But before they numbered only four. The fact is that not all geographers and oceanographers recognize the existence of a separate Southern Ocean, which is still called the Antarctic Ocean. This huge reservoir of water surrounds Antarctica, and its boundary is most often conditionally carried along the sixtieth parallel to the southern latitude. The largest one belongs to the Pacific Ocean, its area is almost 180 million square kilometers. km. It is here that the deepest place on the planet is located - the Mariana Trench. Its depth is 11 km. The Pacific Ocean, washing the shores of East Asia, Australia, North and South America, is characterized by an abundance of islands, most of which are located in the west and in the center. The second place is occupied by the Atlantic Ocean. According to the area of water expanses, he is about half the size of Tikhom. The waters of the Atlantic are washed by Europe, the western part of Africa, the eastern regions of the two American continents, and in the north by Iceland and Greenland. The Atlantic Ocean is extremely rich in commercial fish and underwater vegetation. The Indian Ocean is somewhat smaller in size than the Atlantic Ocean. As its name implies, it is located near India, washing also the eastern coasts of Africa, the western edge of Australia and Indonesia. This ocean has in its composition a very small number of seas. The Arctic Ocean is least explored. Its area is just over 14 million square meters. km. This water basin is located in the inaccessible northern part of the planet. Almost all year round its surface is covered by powerful ice. The lack of light and oxygen in the water depths led to the poverty of the animal and vegetable world of this ocean.
