2/3 of the Earth's surface is occupied by the oceans, and only 1/3 is land.

The continents divide the World Ocean into 4 oceans.

Pacific Ocean

The largest in area. It occupies half the area of ​​the World Ocean and about a third of the area of ​​the globe. That is why they call him the Great. It owns 20 seas and over 10,000 islands. Called him quiet Magellan , because during his long journey across the ocean there was not a single storm.

The bottom of the Pacific Ocean is heterogeneous, there are underground plains, mountains and ridges. On the territory of the ocean is the Mariana Trench - the deepest point of the World Ocean, its depth

Atlantic Ocean

Second by size. The mid-ocean ridge crosses the ocean floor from north to south.

Indian Ocean

Third largest. It is located predominantly in the southern hemisphere.

The water temperature in the Indian Ocean ranges from -1°С off the coast of Antarctica to + 30°С near the equator, the average water temperature is +18°С.

• The smallest of the four oceans. It is located in the northern part of the world. Most of The Arctic Ocean is covered with a layer of ice - in winter it is almost 90% of the ocean's surface.
• Only near the coast ice freezes to land, while most of the ice drifts. The ocean is completely located in the northern latitudes, it has a cold climate.

The world's oceans The ocean is not just a body of water, it is full of life, sometimes much more diverse than the land. In total, there are five oceans on earth: the Atlantic, Pacific, Arctic, South Arctic and Indian. Scientists estimate the number of inhabitants of the ocean as more than two hundred thousand diverse organisms. The permanent inhabitants of the ocean waters, in addition to a variety of fish, are crustaceans, cetaceans, turtles, cephalopods (squids, octopuses, etc.), benthos and plankton.

Seaweeds Seaweeds are ancient, stratified spore plants containing chlorophyll in their cells and living mainly in water. Such a definition, however, does not give an idea of ​​the enormous diversity in body structure that is characteristic of seaweeds. Here we meet with unicellular and multicellular, and with large forms of various structures. There is great diversity in the methods of reproduction. Even in color, seaweeds are not the same, since some contain only chlorophyll, others still have a number of additional pigments that color them in different colors.

Corals Coral is the skeletal material of a colony of coral polyps (“bioherms”). Large accumulations of coral form coral reefs and coral islands. The color of corals depends on the composition and amount of organic compounds: there are not only pink, but also red, blue, white and even black corals. Red corals are called "blood foam", "blood flower", black - "royal corals". Pink, red and black corals are considered the most valuable.

Whales Whales are marine mammals from the order of cetaceans, not related to either dolphins or porpoises. Orcas ("killer whales") and pilot whales have the word "whale" in their informal names, although they are strictly classified as dolphins. Whales switched to an aquatic lifestyle about 50 million years ago. Cetaceans are divided into two suborders: Whales are marine mammals from the order of cetaceans that do not belong to either dolphins or porpoises. Orcas ("killer whales") and pilot whales have the word "whale" in their informal names, although they are strictly classified as dolphins. Whales switched to an aquatic lifestyle about 50 million years ago. Cetaceans are divided into two suborders: Baleen whales, distinguished by their whiskers, a filter-like structure located on the upper jaw, consisting mainly of keratin. The mustache is used to filter plankton from the water. Baleen whales are the largest suborder of whales. Baleen whales, distinguished by their baleen, a filter-like structure located on the upper jaw, composed mainly of keratin. The mustache is used to filter plankton from the water. Baleen whales are the largest suborder of whales. Toothed whales have teeth and prey on fish and squid. The remarkable ability of this group is the ability to feel them. environment using echolocation. Toothed whales have teeth and prey on fish and squid. The remarkable ability of this group is the ability to sense their environment through echolocation.

Dolphins Dolphins are characterized by the presence of relatively small muzzles; body small muzzle; the body is elongated; has a dorsal fin. elongated; has a dorsal fin. Very agile and agile, Very agile and dexterous, voracious predators, living mostly socially; found in all seas. voracious predators, living mostly socially; found in all seas. Feeds mainly Feeds mainly on fish, mollusks, fish, mollusks, crustaceans; sometimes crustaceans; sometimes they attack their relatives. They are also distinguished by curiosity and traditionally good attitude to a person.

Crabs The head of the crabs is small, the short abdomen is symmetrical and bent under the jaw and chest. They live in the seas, fresh waters and on land. Sometimes photos reach huge sizes. The giant crab, caught off the coast of Japan, had a distance between the ends of the claws of 3.69 m. There are over 6780 species in the world.

Sharks Sharks are a superorder of cartilaginous fishes, including eight orders, twenty families, and Sharks are a superorder of cartilaginous fishes, including eight orders, twenty families and about 350 species. Representatives of the superorder are widespread in all seas and about 350 species. Representatives of the superorder are widespread in all seas and oceans; freshwater sharks are also found. In most oceans, freshwater sharks are also found. Most species belong to the so-called true predators, species belong to the so-called true predators, some species, in particular the whale, giant and individual species, in particular the whale, giant and largemouth sharks, feed on plankton. Largemouth sharks feed on plankton.

Most of the species belong to the so-called real predators, some species, in particular whale, giant and largemouth sharks, feed on plankton.
