Sea is the
salty water that covers over 70 percent of the earth surface.
Most
abundant water is sodium chloride it also contains magnesium, calcium and many
other elements.
What is very
interesting is that in the seas happens something eccentric for the humans to
see, there is a line which splits the salted water and the sweet one and you
still see nothing obvious making those two waters not to mix together.
In the sea
is a wide variety of living creatures, there are plants and lot of animals
which man has never seen yet and there is a saying “What does not have in the
sea”.
As the
sunlight penetrate in the water so the living species differs .
In the deep sea there are found creatures
without eyes because they don’t need
them as the light goes deep in water only 200 meters.
The sea is
so important for the humans, besides they take salt, food and different useful things
from people use the sea to travel through it. Indeed the most known transport is
made across the seas and oceans too, carrying goods from a country to another.
As we now
know there are many benefits from water and the sea, people also relax
themselves in summer times visiting beautiful beaches but what’s most important
is, is that the sea itself gives the nature and whole globe its wonderful view.
