because of evaporation
AnswerAll oceans have salt in them. The average salinity of all oceans is 35 parts per thousand. Salinity does vary according to depth and location. Areas of the ocean located near onshore river runoff typically have a lower salinity. Areas near the tropics with high evaporation rates tend to have higher salinity.
The average ocean salinity is around 3.5%. It is typically measured in parts per thousand (ppt) or in PSU (practical salinity units), with most oceans having a salinity close to this average value.
near the desert(30 degrese latitude) more water is evaporated than returned to the ocean by rainfall or rivers\canals.thereforth the ocean salinity near the deserts would be higher than most other latitudes
The ocean water that is most saline is typically found in areas such as the Red Sea and the Persian Gulf. These regions experience high evaporation rates and limited freshwater input, leading to increased salinity. The Red Sea, in particular, can have salinity levels exceeding 40 parts per thousand, making it one of the saltiest bodies of water in the world's oceans.
in the ocean
The top most layer has more salinity. But ignoring thermo-haline currents.
Skeletal muscle is most often controlled by conscious thought.
The sea has to have at least 4 tablespoons of salt in order for an egg to float.
Most water is evaporated from oceans.
there are no oceans in Spain
nobody owns oceans...
