Answer: True
Ocean water is saline. The salt in the ocean comes from rocks on land. The rain falls on the rocks erodes the rocks . The rain being acidic in nature due to the presence of carbonic acid creates ions, or electronically charged atomic particles. These ions are carried away by the streams of rivers and ultimately to oceans. The two of the most abundant ions produced by this process are sodium and chloride. These make up 90% of dissolved ions in the ocean. The concentration of the salt in seawater is about 35 parts per thousand. In other words about 3.5 percent of the weight of seawater comes from the dissolved salts.
