The ocean's salinity remains the same because of all of the salt spray. It is always spitting out salt from the ocean. Also the sea life uses the salt in various ways. Another reason is that rocks take salt from the ocean as they form over time.
i think no.
well yes, that is true because everything says its true...
The level of saltiness in the oceans can vary depending on factors such as evaporation, precipitation, and river runoff. Salinity can be higher in regions where evaporation is high and lower in areas with more rainfall or freshwater input from rivers. This variability results in different salinity levels in different locations within the oceans.
yes..somewhat. It states that the ratio of major salts in samples of seawater from various places is constant. It can give you a rough answer to salinity ,but salinity varies because of elements not included in the major salts of the ocean. If there were no other factors then it would be able to tell you the salinity.
No, the amount of salt in oceans can vary due to factors such as evaporation rates, precipitation, and inflow of freshwater from rivers. The Atlantic Ocean is generally saltier than the Pacific Ocean due to differences in these factors.
The Atlantic and Pacific are oceans, not "seas". The salinity is about the same, so there isn't much difference in being able to float. The Dead Sea has a very high salinity, and it's very easy for people to float there. Same with the Great Salt Lake.
Nothing. They always remain the same.
yes.
Mitochondrial DNA will remain the same for generations and they are inherited from the mother.
There are processes that increase salinity of the oceans and factors that decrease salinity. Evaporation causes the salinity of the ocean to increase. This is the primary process taking fresh water out of the oceans. Fresh water enters the ocean through rain and rivers. Rivers bring in a small amount of new salt and dissolved minerals that remains after evaporation. Freezing also affects salinity. Near the poles, particularly the antarctic, when ocean ice freezes it eliminate a significant amount of salt from the ice, leaving a saltier and denser brine behind. This denser antarctic brine sinks and initiates a current the flow from the antarctic water northward towards the deeper ocean. This is an important influence on circulation in the southern oceans. The increase salinity of the oceans is also counteracted by processes in the oceans sediments that remove salt so on the average there has been little change in ocean salinity over the last few billion years. Note: Ocean salt, as described here, is not merely sodium chloride, but also has a fraction of other dissolved ions. See related questions.
It doesn't ... its always changing.
Mostly with some exceptions .
