It has effect on the marine life, especially in the anufacture of food.
Yes. It does.
There are different kinds of process that deeply affects the salinity of ocean water. Continental deflections, Coriolis Effect, convection current and also evaporation.
A river flowing into the sea is causing the decrease in salinity
Biomass and temperature, erosion and mineral content.
Low salinity, often found in areas with significant freshwater input, can reduce water density, causing it to rise and potentially leading to less vertical mixing. High salinity increases water density, promoting sinking and contributing to deeper ocean currents. Together, these variations in salinity drive thermohaline circulation, which plays a crucial role in global ocean currents and climate regulation. Thus, salinity influences both the stratification and movement of ocean water.
Storms at sea. The evaporated water falls back into the ocean with no net effect on salinity.
You could increase the salinity of the ocean by adding salt or removing water (ie: by evaporation).
In open ocean evaporation affects the salinity of the oceans, in closed oceans the lack of sunrays cause greater salinity levels.
Rainfall does not directly affect ocean salinity, as rainwater is freshwater and dilutes the salt content in the ocean. Other factors such as evaporation, ice formation, and river input can influence ocean salinity levels.
No, human blood is not as salty as the ocean. The salinity of human blood is around 0.9, while the salinity of the ocean is about 3.5.

Three factors that affect ocean currents are wind patterns, the Earth’s rotation (Coriolis effect), and differences in water temperature and salinity. Wind drives surface currents, while the Coriolis effect alters their direction based on the hemisphere. Additionally, variations in temperature and salinity create density differences in water, influencing deeper currents in the ocean. Together, these elements shape the complex movement of ocean waters.
