What are clouds? Why does it rain?

Category: Science

Answer:

When water evaporates, water vapor is exhausted. Water vapor is essentially very small drops of water that are invisible to the naked eye. As the water vapor rises it groups together and slowly cools and condenses onto dust particles. These dust and water groups become visible clouds. If the clouds are large enough and hold enough water they no longer are lighter than air and they fall as rain or snow.
