Why is the sea salty? The question that many people ask themselves has interested scientists for centuries. The salinity of the seas and oceans varies considerably, but it is mainly influenced by two factors, which are sometimes joined by a third. Basically, the sea is salty due to ionic reactions between sodium and chlorine.
The salinity of the sea comes from two main sources. sea, and the second is hydrothermal deep-sea springs. Volcanic eruptions also appear as a third factor, which also contributes to the salinity of the sea.
Why is the sea salty and what affects the salinity of the sea and oceans
The two most common ions in seawater are chloride and sodium. Together they account for about 85% of all dissolved ions in the ocean. Of this, 55% are chlorides and 30% are sodium ions. Magnesium and sulfate ions account for around 10%.
If we look at the first reason, which is also the main one. Rainwater that falls on the ground is slightly acidic, so it erodes rocks. This buy email database releases ions which are carried by streams and rivers to the sea and ocean. Many of the dissolved ions are used by organisms in the ocean and removed from the water. Some, however, do not and consequently accumulate. Another reason is the hydrothermal fluids that come from open places on the seabed.
The first is water that flows down rocks into the
These deep-sea springs leach minerals such as sodium and chlorine into the seawater. The third factor is the eruptions of sea backlinks are beneficial to both parties. volcanoes. Namely, seawater pours into cracks on the seabed and is heated by magma from the earth’s core. The water usually loses oxygen, magnesium and sulfates and picks up metals such as iron, zinc and copper from the surrounding rocks.
One of the interesting reasons that cn leads contribute to the salinity of the sea are the salt domes that are common on the continental shelf of the northwestern Gulf of Mexico. Namely, these domes are extensive deposits of salt that are formed over geological time periods.
