Observing various weather phenomena

How does rain occur? Miss Siham explains that rain is a form of precipitation and that it comes from a cloud. The sun heats up the sea: this heating creates evaporation. When this water vapor rises, it cools and forms a raindrop. When raindrops converge we get a cloud, and if the cloud becomes too heavy then raindrops fall. Miss Siham also explains why it rains so often in Belgium and hardly not in a country such as Italy: it has to do with mountains, altitude, temperature and wind. Finally, she also mentions the phenomenon of snow and hail.
