how does the water cycle work?
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.
Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request.
