How does the water supply work in the oceans?

The water supply in the oceans is part of the Earth's hydrological cycle, where water evaporates from the surface, condenses into clouds, and falls back to the surface as precipitation. Oceans cover about 71% of the Earth's surface, acting as the primary reservoir for this water. The constant movement of water through evaporation, precipitation, and ocean currents helps maintain a balanced supply. Additionally, rivers and streams feed into the oceans, replenishing their water content.
