Is the water on the shore renewing itself or is it more or less the same?

Answer 1

I’m not sure what you mean by renewing itself.

But water is water. Unless a comet hits us and gives us some more, we have what we have.

The water from the ocean evaporates and ends up in clouds. Those clouds move inland and rain down on the land, or snow. The rain/snow (after it melts) flows into rivers and lakes, which eventually makes itself back to the Ocean.
