Answer / nilanjan saha
Sea water has been defined as a weak solution of almost
everything and is indeed a complex solution of mineral salts
and of decayed biologic matter resulting from the teeming
life in the seas. Most of the ocean's salts were derived
from gradual processes such the breaking up of the cooled
igneous rocks of the Earth's crust by weathering and
erosion, the wearing down of mountains, and the dissolving
action of rains and streams which transported their mineral
washings to the sea. Some of the ocean's salts have been
dissolved from rocks and sediments below its floor. Other
sources of salts include the solid and gaseous materials
that escaped from the Earth's crust through volcanic vents
or that originated in the atmosphere.

The sea contains solid rocks made of salt at its bottom.
Moreover, rivers also bring salt deposits.

Answer / satish
Water always contains dissolved solids with solution. These
may have been picked up from a variety of sources. As it
evaporates during it's cycle, the evaporated wate leaves
behind the dissolved soilds in the solution. The sea being
the largest water body, has to therefore hold these salts
left behind due to evaporation. This is a "concentration
mechanism". So the salt content ceaselessy build up in the
sea.
Other water bodies, like rivers, are not salty because they
are flowing. Flowing results in dilution as well, so
salinity does not build up in rivers.
Lakes receive inputs from rivers so the salinity is diluted.

Answer / neha gupta
We can summarize this discussion. Wherever water comes into
contact with the rocks of Earth’s crust, either on land or
in the ocean or within the oceanic crust, some of the
minerals in the rock dissolve and are carried by the water
to the ocean. The salt content of seawater does not change
because new minerals are forming on the sea floor at the
same rate as salt is added. Thus, the salt content of the
sea is at steady state.
