               NOTES:

                   •  Moving air is called wind.
                   •  When light and pleasant wind moves gently, it is called  breeze.

                   •  Strong and fast-moving winds are called storms.

               SEA BREEZE:

                   •  The land heats up faster during the day, as compared to water in the

                       sea.
