Question

What is the basic ingredient of all clouds?

Answer 1

Water vapor is the basic ingredient

Answer 2

Clouds are visible collections of tiny water droplets which present high in the atmosphere above the Earth's surface. The ingredients to form clouds are water, cooling air temperature and a surface to form on (nuclei). Clouds begin to form when amount of air rises from the surface up into the atmosphere. The water vapor in the air is not visible most of the time. When it collects and condenses then a cloud is formed.
