why sea water is hard?

The oceans have been around a
very long time, so some of the
salts were added to the water at
a time when gases and lava were
spewing from increased volcanic
activity. The carbon dioxide
dissolved in water from the
atmosphere forms weak
carbonic acid which dissolves
minerals. When these minerals
dissolve, they form ions, which
make the water salty. While
water evaporates from the
ocean, the salt gets left behind.
Also, rivers drain into the
oceans, bringing in additional
ions from rock that was eroded
by rainwater and streams.

Rain replenishes freshwater in rivers and streams, so they don't taste salty. However, the water in the ocean collects all of the salt and minerals from all of the rivers that flow into it.
