ithnkts beacouse of the rain water and all of the non living thigs that live there
The salinity in isolated seas and salt-water lakes (for example, the Dead Sea) can be considerably greater. SO there's a high salinity in the Dead Sea. :D
The higher the salinity of the water the easier it is to float - the Dead Sea, the Caspian Sea, the Great Salt Lake.
A palaeosalinity is the salinity of the seas in the geological past.
There are several factors that affect salinity. Some of the main factors include evaporation and precipitation which will affect the salinity of oceans and seas.
Red Sea and Persian Gulf are the areas with the highest salinity. Then the areas with lowest salinity would be the polar seas (or seas near to the polar tips), and sometimes some seas near a fresh body of water. For example, the South American area near Amazon River only has an average salinity of 28 o/oo. The Baltic Sea may have an average salinity of 5 o/oo. Hope this helps!!
The world's oceans have a salinity of about 3.5%
Yes. Chloride concentration increases with the seas depth. This is because chloride increases the salinity of the water. The more saline the water, the denser it becomes. Dense water, even if it is slightly denser, tends to sink below.
The Atlantic and Pacific are oceans, not "seas". The salinity is about the same, so there isn't much difference in being able to float. The Dead Sea has a very high salinity, and it's very easy for people to float there. Same with the Great Salt Lake.

Historically, many large bodies of water, especially navigable ones, were called "seas." There are notably the Caspian Sea and Aral Sea, both large lakes. The Dead Sea is called "dead" for the lack of fish or other marine life, due to the extreme salinity of the water. For saline content, it is the third most concentrated body of water on Earth, and the most accessible.
Caspian, Dead, Aral, Black seas.
