Because the liquid water is released as a gas by boiling.
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.
Dissolved salts are transported by the rivers.
Precipitation, land water runoff and the melting of icebergs do not add salts to seawater.
Minor organic salts make up less than 1% of the composition of seawater.
Seawater is hypertonic to drinking water. This means that seawater has a higher concentration of solutes (such as salts) compared to drinking water. Drinking seawater can lead to dehydration as the body would need to excrete more water to get rid of the excess salts.
Desalination. Desalination is the process of removing salts and minerals from seawater to make it suitable for consumption or agricultural use.
Seawater contains dissolved salts, primarily sodium chloride, which give it its salty taste. The salt in seawater comes from the erosion of rocks on land, which release minerals into rivers that eventually flow into the ocean.
The average salinity of seawater is about 35 grams of dissolved salts per kilogram of seawater, or 3.5% by weight.

Volcanoes add various salts to seawater, primarily including sodium, potassium, calcium, magnesium, and chloride ions. These salts are released into the ocean through volcanic eruptions, where gases and ash interact with seawater, or through hydrothermal vents on the ocean floor. The high temperatures and pressures associated with volcanic activity can also lead to the leaching of minerals from surrounding rocks, further contributing to the salinity of seawater.
The process that contributes the most to the salts found in seawater is weathering and erosion of rocks on land. As rainwater, which is slightly acidic, flows over rocks, it dissolves minerals and releases ions such as sodium, chloride, magnesium, and calcium into rivers. These ions eventually reach the oceans, where they accumulate over time, contributing to the salinity of seawater. Additionally, hydrothermal vents and volcanic activity also contribute some salts, but the majority comes from terrestrial sources.
