The average salinity of seawater is 35 parts per thousand (or ppt).
No, increasing salinity results in higher density. This density increase means you will also be able to float more easily in more saline water. The higher the salinity the lower the temperature it will freeze.
Higher levels of salinity produce brine shrimp that are smaller, but reach sexual maturity faster than those in lower levels. Also lower levels of salinity tend to allow more predators into the ecosystem.
Coastal waters have a lower salinity due to the vast amount of freshwater runoff pouring into the sea from rivers and streams. PM
The higher the altitude the colder the climate, the warmer the climate the lower the altitude.
the lower the latitude the higher the temp.
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.
Seawater's density varies by temperature and salinity. I.e., cold water is more dense than warm water, and water with a higher salinity (more dissolved salt) is less dense than water with a lower salinity.
Yes. It can be higher or lower
River water has a higher salinity, which means there is a lot of salt in the water. In the sea, however, the salt sinks to the bottom of the ocean, so the sea water has a lower salinity.
Wouldn't heavy rain, say from a hurricane cause a higher than usual runoff of fresh water from the land area? And the rain that drops in the sea is fresh too.
The higher the saline content in water the heavier the water. This causes it to sink towards the bottom and water with lower levels will rise to the top. It will remain so unless stirred vigoriouly and often. Many animals live, and thrive in this setting, such as salt marshes, springs, also some ponds and lakes.
