Excessive freshwater (rain) flowing into a shallow sea can change the salinity.
Excessive freshwater (rain) flowing into a shallow sea can change the salinity.
You could increase the salinity of the ocean by adding salt or removing water (ie: by evaporation).
The lowest areas of salinity in an ocean are near where fresh water rivers empty into them. This is because the influx of fresh water creates an area of lower salinity compared to the remainder of the ocean.
There are a number of things that could happen to the salinity of an ocean if it's depth increased. The salinity would likely also increase.
rain, snow, and melting ice add fresh water to the ocean, lowering the salinity there. Salinity is also lower near the mouths of large rivers. These rivers empty great amounts of fresh water into the ocean.
some areas have a higher and lower elivation witch causes it to be deep or shallow
ocean because the ocean or you could say the sea is filled with salt water. :)
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.
Ocean biomes typically have a salinity range of about 30 to 37 parts per thousand (ppt), which translates to 3% to 3.7% salt content. This salinity can vary depending on factors like location, depth, and proximity to freshwater sources. Coastal areas may have lower salinity due to river inputs, while more isolated regions, like the open ocean, may have higher salinity levels. Overall, the average salinity of ocean water is approximately 35 ppt.
Lower rates of evaporation so more water to dilute it.
A river flowing into the sea is causing the decrease in salinity
The continental shelf is the shallow part of the ocean.
