The cycle of the sea

Life at sea and life on land are closely linked. The ocean depends on us and affects our existence more than we think.

The first astronauts who were able to admire the spectacle of the planet below them called the Earth “the blue planet”, because the ocean covers 71% of its surface. Thanks to the sea, ours is the only planet to host life, among those known – and those who do not live in the sea create a miniature one in their cells, which contain liquids with a saline concentration similar to that of the sea.

The astronauts also saw the whiteness of the cloud systems, which are composed of sea water evaporated with the heat of the Sun and turned sweet, having left the salts in the liquid part.

THE BLUE PLANET - The cycle of the sea

The cycle of the sea – The air currents then carry the clouds to the continents, where the water falls in the form of rain, snow or hail, allowing life even in the emerged portion of the planet. If you are far from the sea and you want to see it, look up: the clouds are the ocean and, when it rains, it is the water of the Atlantic that bathes us, and then returns to the sea through the rivers.

It is the heat that circulates the water in the atmosphere, causing it to evaporate, while the cold (together with the wind) generates the ocean circulation. At the poles, in fact, sea ice is formed which, like steam, is made up of fresh water.

The salts left in the liquid part, combined with the low temperature, increase the density of the water on the surface of the polar seas, causing it to sink. In this way, currents are triggered (characterized by low temperatures and high salinity) that set in motion a large conveyor belt: a flow that connects all the oceans in a single, wide circulation. Water takes about a thousand years to travel around the world.

Therefore, atmospheric currents generated by heat and ocean currents generated by cold distribute water to every corner of the planet, and keep it alive… this is the cycle of the sea
