What else can I help you with?
What lowers the salinity near the surface of the ocean?
evaporation
What does not affect ocean salinity?
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.
What two factors can affect salinity?
Ocean currents,The sun,and human activities
Does industrial polutants affect ocean surface salinity?
hi
Suppose the salinity of surface ocean water is high in a particular place what might you infer about the area's rates of evaporation?
If the salinity of surface ocean water is high in a particular place, it suggests that there is high evaporation rates in that area. As water evaporates, it leaves behind salt, increasing the salinity of the remaining water.
List three factors that affect salinity in the ocean and three factors that affect ocean temperatures. Explain how each factor affects salinity or temperatures?
Three factors are evaporation and freezing of sea water.
What is the range for annual mean ocean surface salinites?
The annual mean ocean surface salinity typically ranges from about 30 to 37 practical salinity units (PSU). This variation is influenced by factors such as evaporation, precipitation, river runoff, and ocean circulation. Regions near the equator often have lower salinity due to high rainfall, while areas in subtropical regions can have higher salinity due to increased evaporation.
Do high evaporation rates in the subtropics cause the surface ocean water to have a lower than average salinity?
High evaporation rates in the subtropics typically lead to increased salinity in surface ocean waters, not lower. As water evaporates, salts and other dissolved substances remain, concentrating in the remaining water. However, in some regions where precipitation or river influx balances or exceeds evaporation, salinity may be moderated. Overall, the general trend in subtropical regions is for evaporation to increase salinity.
How does evaporation affect salinity near the equator?
Evaporation near the equator increases the salinity of the ocean water because it removes fresh water and leaves behind the salts, making the water more saline. This can lead to higher salinity levels in tropical regions compared to other areas of the ocean.
What affects the salinity of ocean water?
evaporation
Does high evaporation rates in subtropics cause the surface ocean water to have a lower than average salinity?
No, high evaporation rates in subtropical regions typically lead to higher salinity in surface ocean waters. As water evaporates, it leaves behind salts and other dissolved substances, concentrating them in the remaining water. This results in elevated salinity levels, contrary to the idea of lower-than-average salinity.
The salinity of the ocean?
You could increase the salinity of the ocean by adding salt or removing water (ie: by evaporation).
