Question

why is sea water salty or saline​

Answer 1

Answer:

Ocean salt primarily comes from rocks on land. ... Rainwater that falls on land is slightly acidic, so it erodes rocks. This releases ions that are carried away to streams and rivers that eventually feed into the ocean. Many of the dissolved ions are used by organisms in the ocean and are removed from the water.
