Chemical weathering and out gassing
The two primary sources for dissolved components in seawater are weathering of rocks on land, which releases minerals into rivers and eventually the ocean, and gases released by volcanic activity. These sources contribute ions like sodium, chloride, calcium, and magnesium to seawater.
Seawater is a mixture. It is composed of water, various dissolved salts and minerals, gases, and organic matter. These components can be physically separated through processes such as evaporation or filtration.
On average, seawater contains about 35 grams of dissolved substances per 1,000 grams of water.
Seawater is a mixture of different elements and compounds. It is primarily composed of water and contains dissolved salts, minerals, and other substances. So, seawater is not an element but a complex mixture of different compounds.
Seawater contains a variety of dissolved substances, with the most abundant being sodium and chloride ions from salt (sodium chloride). Other common elements and compounds found in seawater include magnesium, calcium, sulfate, and bicarbonate ions, as well as dissolved gases like oxygen and carbon dioxide. Organic matter including proteins, carbohydrates, and fats also exist in seawater in smaller amounts.

The dissolved materials in seawater are thought to originate from the weathering of rocks on land, as well as from volcanic activity and chemical reactions at hydrothermal vents on the ocean floor. These processes contribute minerals, salts, and organic matter to the water, creating the diverse composition of seawater.
Salinity refers to the salt content in seawater, specifically the concentration of dissolved salts such as sodium and chloride ions. It does not include visible solid materials like sand or rocks that may be present in the water.
The dissolved materials in seawater originate from various sources such as weathering of rocks on the Earth's surface, volcanic activity, and chemical reactions between water and minerals. These processes release ions and compounds into water that eventually flow into the oceans.

Dissolved salts are transported by the rivers.
The most negatively charged ion dissolved in seawater is chloride. In fact, Cl- makes up 55 percent of the seawater's salinity.

Rainfall is NOT one of the sources of dissolved salts in seawater. Salt in seawater comes from the erosion of rocks on land, underwater volcanic activity, and the release of minerals from hydrothermal vents.
These ions are Na+ and Cl-.
