Without the atmoaphere there would be no weather ,wind ,rain ,snow or clouds .Air is all around us ,we live at the bottom of a great ocean of aiir .It is invisible ,but we can feel it when it moves .There are miles of air above us ,pressing down with great weight on the earth and everything on it .Because air presses down on us from all__48__at the same time ,and because we are able to bear this weight ,we do not seem to feel it ,However,scientista have proved that air has this weight ,ang that __50__that has weight creates a force called pressure .As changes in air pressure take place ,they make air__51__.
Air ia agas that expands when heats ,gets lighter ,and moves __52__.When air is cooled ,it gets heavier ,sinks close to the earth's surface ,and flows like water in a great river ,As warm air rises,cold aie rushes __53__ to make its place .Thus wind originates .The wind that blows igh above us is caused by the warmer air running away from __54__ air .The wind we feel near the earth's surface is the heavy colder air trying hard to __55__the warmer air .Changes in temperature cause the air to move .
