Because as rocks weather, small amounts of salts are released into the water flowing over and through the rocks. Most of this water eventually flows into the oceans and marginal seas. The only way for this water to get back out of these basins is through evaporation. As the water evaporates, it leaves behind the salts that were dissolved in it. Thus the concentration of salt in sea water rose. There are other mechanism at work that are also removing salts from sea water. As a result of these processes, the concentration of salts in seawater is now pretty constant. However, this is from where the salt comes.

Because, in the earth, there is no other place to keep the salt...without harming the natural ecosystem......salt when dissolved in water are diluted in concentration and hence more lives can survive....So, god has good idea where to keep the things...and he placed the salt stock in the sea.
