What role does a sea play in the water cycle?

The sea plays a crucial role in the water cycle by acting as a primary source of evaporation. Water from the ocean's surface evaporates into the atmosphere, forming water vapor that contributes to cloud formation. When these clouds cool and condense, they produce precipitation, which can return water to the sea or land, thus continuing the cycle. Additionally, the sea helps regulate global temperatures and climate patterns, further influencing the water cycle.
