1.   Methane condenses to form a cloud layer above the ammonia clouds, leaving a gas that is almost entirely hydrogen and helium.

2.   Water vapour condenses to form clouds.

3.   Moisture in the air condenses to form tiny drops of water.

4.   As the air is sucked into the updraft, the moisture in it cools and condenses to form funnel-shaped clouds.

5.   Air rushing into the spinning updraft cools and its water vapor condenses to form a funnel cloud.

6.   The water vapor thus produced condenses to form storm clouds, releasing latent heat into the atmosphere in the process.

7.   Eventually the gas cooled and condensed to form stars and which then formed galaxies of stars.

8.   Scientists believe that as stars age, this dust condenses to form planets.

9.   When the water vapour rises, it cools and condenses to form clouds.
