1. The most important part of the sodium and chlorine are dissolved from the earth salts and transported by rivers in seas/oceans.
2. A small part of chlorine is originated from the eruptions of submarine volcanoes.
There are several routes: rain water, particularly acid rain, can react with rocks and siol to create salts which are then washed down through streams and rivers to bodies of saltwater. Underwater volcanic eruptions also contribute chemicals which may react to produce salts.
Saltwater is a solution because you can get fresh water and some salt and mix it and then you get saltwater.
