The warm ocean
The surface layer of the oceans is heated by solar rays and the thickness of the heated layer is no more than a few meters. Below this level the water is cold, but in deeper layers it has a temperature that does not exceed plus 2 degrees. But, despite the fact that all the oceans of the world is in deep layers is not very high, the temperature of the water is the warmest ocean. This recognized the Pacific ocean, is also considered as a kind of champion the title of «most-most».
Why is it the warmest of all?
If you’re wondering which ocean is the warmest, the answer is clear – the Pacific ocean, which for the most part located in the region of the equator. But the closer the ocean to the equator, the warmer it water. The average surface water temperature plus 19 degrees. A little colder waters of the Indian ocean – the water temperature here averages plus 17 degrees. And the cold is the Arctic ocean – the water temperature is a bit more plus 1 degree.
In the summer the ocean waters of the earth warm, and in winter is their slow cooling, in which ambient air is given heat warms the surrounding air, like a battery. Scientists have concluded that it is not akkumuliruya the oceans warm, the average temperature for the planet would have amounted to plus 21 degrees, and it would lead to a completely different level of existence of mankind.
Not only warm, but also huge!
The Pacific ocean can be called the best in many ways. In addition, he is recognized as the most warm, it also has quite a huge size, which can be called the biggest and deep. As is the ocean in different climatic zones, and the length of its incredibly large. The most large is considered to be the Equatorial zone of the ocean where the water temperature is not less than plus 25 degrees.
The volume of water in the ocean is equal 723000000 km3. From North to South it stretches for 15800 km, and from East to West – 19500 km. In area the warmest ocean in the world equal to about 180000000 km2.
It is known that the vast expanse of the ocean was able to see the Conquistador Balboa crossed in the 16th century, the isthmus of Panama. In those days he called the waters the «South sea.» But later the Navigator of Portugal F. Magellan called it Pacific ocean is huge, since crossing it for a hundred and ten days the weather was surprisingly calm, no storms.
The topography of the bottom
The ocean floor has quite a large variety. For example, in the Eastern Pacific ocean there is a smooth bottom. And in its Central part there is the chute and basin. The deepest spot in this area is the Mariana trench which deepens almost 11000 km. This basin represents the deepest place on the planet. At the bottom of the Pacific ocean has significant deposits of natural resources (for example, there is approximately forty percent of the world’s reserves of «black gold»).
The inhabitants of the ocean
Since the ocean is approximately half of the available surface water on Earth, its flora and fauna is quite diverse. Ocean waves live more than a hundred thousand species of marine life. Most life exists in the tropical zone. And currently, oceanographers open the previously unknown animals that live here.
Despite the fact that it is home to many species of animals, their number can decrease due to the influence of man on nature. The Pacific ocean is now recognized as contaminated. Environmental problems led to the fact that you disappear some types of plants and animals. For example, before the twentieth century, it almost became a seal and some whale species. And the culprit the pollution of waters by oil and various industrial wastes. Also an annual increase in the number of discharged into the waters of the ocean of garbage. Located five kilometers from California to the garbage spot gradually increases in size. And to prevent death of plants and animals it is important that people think and learn to protect nature.
