How much salt goes into the ocean each year? BEST ANSWER GETS 10 POINTS

i was just curious about this

Rivers carry dissolved chemical substances into the ocean.

The chemicals are mostly bicarbonate, silica, and SALTS which comprise about 4.6 billion tons of sediment added to the ocean each year.

That probably depends on a variety of conditions.

WHY DO POSTERS SAY; "BEST ANSWER GETS 10 POINTS?"

That is so tacky and childish. We know that the best answer gets 10 points. If you choose not to pick someone, that's OK.
