The oceans will not keep getting overall saltier and has varied very little over the last 1.5 billion years. They have had the same average salinity for a very long time now because even thou rivers deliver salt in them there are processes that take it out. This is called residence times, the time needed to completely replace the amount of a given substance in the ocean. Subduction of the tectonic plates is actually a very broad simple answer. To go into more depth a sea gets closed off partially or entirely. The sea will then start a long process of drying up at a very slow rate. The end of the process is the formation of salt deposits. This is happening in the Red Sea and the Gulf of California and happened to the Mediterranean Sea when it once became partially cut off. Also on a much more minor scale there are some biological processes that remove salt and other dissolved matter. An example of this would be an organism removing calcium and carbon dioxide in shell formation. Last there are chemical reactions between cold seawater and hot oceanic crust that removes dissolved constituents.
So once again to answer your question no the oceans are not getting saltier.

No. One respondent has correctly noted that rivers bring additional dissolved minerals to the sea, but minerals are also being taken from the sea when subduction of the tectonic plates occurs.

No;in fact, water cycle provides further and further salt to the sea.Water cycle consists of the get admission to of water into the ambience(contained in this variety of water vapour) by employing evaporation from the water surfaces and transpiration of the vegetation and the vapour returns to earth as rain and snow. for the period of evaporation from the sea,salt is often left at the back of.So, in destiny, the quantity of salt in seas and oceans will develop purely. guy might get rid of a few salt from the sea for intake.yet which would be negligible.

Only because Jesus and the angels will cry more as the world gets into a sadder and sadder state!

yes. Rivers bring in more minerals, water evaporates and minerals stay.
