Water vapor is not cycled through the atmosphere of the earth. While water does evaporate into the atmosphere and precipitate back to the earth's surface, the water molecules themselves are not cycled through the atmosphere in the same way that gases such as nitrogen and oxygen are.
Yes, weather occurs in all parts of Earth's atmosphere. Different layers of the atmosphere play a role in shaping weather patterns, from the troposphere where most weather events occur, to the stratosphere where the ozone layer impacts temperature, to the mesosphere where meteors burn up.
Yes, our months are based on the movement of the moon around the earth.
