  1. After looking to see if my question had been answered I found yours. And I knew the answer-lucky you!
    Well, when the Earth was first formed it was very hot and volcanic erruptions took place all over the surface. All the water on the planet was vapourised becuase of the heat.
    When the Earth started to cool the water condensed into water, and it rained for centuries until the oceans were formed. The carbon dioxide from the volcanic erruptions dissolved into the oceans making it increasingly acidic. The acid ocean wore away at rocks formed from the volcanic erruptions and also dissolved. The remains of these rocks are the salt in the ocean today. The acid was neutralised by various reactions over time as well. Which is why you dont get acid burns every time you go swimming in the sea.
