is the home for many plants and animals.
Total capacity of hydrosphere is about 1,4 billion km².

takes place under influence of

the solar energy and gravity force, is called world water cycle.

all the dry land.

Arctic Ocean downward to the shores of Antarctica. This

makes it the same size from north to south as the Pacific Ocean. However, from east to west, the Atlantic Ocean is only about half as wide as the Pacific.

smaller than the Atlantic.
The Indian Ocean lies between

Africa on the west, Australia on the east, Asia on the north, and Antarctica on the south. 90% of this ocean lies to the south of the Equator.

Ocean with the North Pole in the centre.
This

ocean is connected to the Pacific and Atlantic Oceans via small gaps between continents.

lithosphere.
There is no general opinion among scientists about upper

and bottom biosphere borders. Living organisms are very closely located in the bottom atmosphere, especially up to 100 meters. Nowadays, taking into account living organisms’ spreading, upper bound of biosphere is drawn along the ozone layer (25-30 km); lower bound is drawn along the bottom of the World Ocean deepest channel.

of the biological cycle are divided into 3 groups:
