how does the water cycle work?


assistant
The water cycle has no starting point, but the oceans seem to be a good starting point. The sun warms the water in the oceans; it evaporates into the air. Rising air currents carry the vapour into the atmosphere, where the lower temperatures cause the vapour to condense into clouds.
