Item WC089001: Clouds form anywhere there is moist air that cools to form tiny water droplets.
Where, if anywhere, can new clouds form?
- New clouds cannot form anywhere. Wind pushes existing clouds from one place to another.
- Although clouds can be pushed from one place to another by wind, new clouds form only near factories and cities because clouds need pollution to form.
- Although clouds can be pushed from one place to another by wind, new clouds form only over lakes or oceans, because clouds need a body of water below them to form.
- New clouds can form wherever there is moist air that cools to form tiny droplets of water.
