1. As the rain erodes the rock acids in the rain water break down the rock.
2. Ions (or) electrically charged atomic particles are created.
3. These ions are carried away in runoff to streams and rivers and ultimately to the ocean.
4. Many of the dissolved ions are used by organisms in the ocean are removed from the water.
5. Others are left for long periods time where their concentrations increased overtime.
6. Sodium and chloride are the most prevalent ions in Sea water, (about 90%) making sea water salty as it is salty
