All-planetary Ocean

From space, our Earth appears blue planet. And not just because most of it encloud, cast blue light under the rays of the sun, but also because most of the planet’s surface form the oceans and seas. And they seem to be blue from space.

From space, our Earth appears blue planet. And not just because most of it encloud, cast blue light under the rays of the sun, but also because most of the planet’s surface form the oceans and seas. And they seem to be blue from space.

Their total area is 2.5 times the area of ??land. Almost three quarters of the globe cover ocean waters, and the layer has an average thickness of about 4 km.

It is no coincidence the ancient people imagined the Earth floating in the ocean on three pillars – so much water on the planet, it seems (and correct) its main element.

Water was mostly sea, ocean.

Scientists offer even select it in a separate envelope the earth – okeaposferu.

After all waters of the seas and oceans are very different from the waters of rivers and lakes in their properties. Their main feature – a high content of dissolved salts.

On average, each liter of sea water solution of 35 g of salt, while in the water of rivers and lakes are no more than 1-2 grams per liter. At the same salt composition of sea water almost does not change, it is permanent.

Because the water that much salt (which is not only common salt, which we solim-food, but also salts of other metals), increases its density and as a result of increased mixing of water in the ocean.

And it gives an opportunity to “ventilate” the immense thickness of the oceans.

Oxygen penetrates very deeply, so that the entire ocean water is drawn into the cycle of energy and matter on the planet, and life is possible and at very great depths.

It is, in fact, originated in the ocean.

And now the living matter in the ocean mass is much greater than on land.

Ocean waters maintain a balance in the nature of the planet.

This water picks up a lot of minerals, gases dissolved in it settle a variety of living organisms.

The lower water temperature, the colder it is, the more dissolved gases passing into the water from the air. Only the ratio of gases is quite different.

Thus, in an atmosphere of nitrogen (by volume) is always 4 times greater than oxygen in ocean water – only 2 times, because oxygen dissolves better nitrogen.

Very much in the water of the ocean carbon dioxide – 60 times more than in-air.

As a great power pump takes the ocean carbon dioxide from the air in the cold regions, giving it back to the atmosphere in the tropics, where it is needed luxurious tropical vegetation.

Ocean – a powerful regulator of heat on the planet.

The great mass of water, warmed, retains heat received from the sun.

After all, even the Arctic Ocean does not freeze to the bottom, and only covered with a thin compared with the thickness of water ice crust.

In winter, the ocean gives an atmosphere of warmth, obtained in the summer.

In the summer the ocean is always cooler than the land and it is closer, the cooler on the mainland.
