Answer 2

Explanation:

Rain replenishes freshwater in rivers and streams, so they don't taste salty. However, the water in the ocean collects all of the salt and minerals from all of the rivers that flow into it. ... In other words, the ocean today probably has a balanced salt input and output (and so the ocean is no longer getting saltier).
