What are the steps in the water cycle?
Water heats up and evaporates, the water vapor rises into the atmosphere, as it gets higher it gets colder, once it gets really cold the water vapor starts to condense into liquid water forming a cloud, when there is enough liquid water in the cloud it rains back down to earth and the cycle repeats.
