Answer 1

The salt in the oceans come from the minerals of the land which are washed into the ocean.

• The source of this salt in the seawater is the minerals which are present in the rocks of the nearby landforms.

• The slightly acidic rainwater falls on these mineral containing rocks and the dissolves the mineral present in those rocks.

• Later that mineral dissolved rainwater get mixed into the ocean water which increases the all over salinity.
