Chapter – 8 (Winds, Storms and Cyclones)<\/span><\/h2>\n

1. Fill the missing word in the blank spaces in the following statements:
\n<\/strong><\/span>(a) Wind is ________ air.
\n<\/span>(b) Winds are generated due to ________ heating on the earth.
\n<\/span>(c) Near the earth\u2019s surface __________air rises up whereas ___________ air comes down.
\n<\/span>(d) Air moves from a region of ________ pressure to a region of ________ pressure.<\/span><\/p>\n

Answer –
\n<\/strong><\/span>(a) Wind is\u00a0moving<\/strong><\/span>\u00a0air.
\n<\/span>(b) Winds are generated due to\u00a0uneven<\/span>\u00a0<\/strong>heating on the earth.
\n<\/span>(c) Near the earth\u2019s surface,\u00a0warm<\/span>\u00a0<\/strong>air rises up whereas\u00a0cold<\/strong><\/span>\u00a0air comes down.
\n<\/span>(d) Air moves from a region of\u00a0high air<\/strong><\/span>\u00a0pressure to a region of\u00a0low air<\/strong><\/span>\u00a0pressure.<\/span><\/p>\n

2. Suggest two methods to find out wind direction at a given place.<\/strong><\/span><\/p>\n

Answer –\u00a0 <\/strong><\/span>Methods to finding out the wind direction at a given place are as follows
\n<\/span>i. By seeing the direction of dry leaves released in the air.
\n<\/span>ii By seeing the direction in which it is difficult to ride the bicycle.<\/span><\/p>\n

3. State two experiences that made you think that air exerts pressure (other than those given in the text).<\/strong><\/span><\/p>\n

Answer –<\/strong>\u00a0We have experienced that when we blow a balloon, the balloon becomes tight. If we try to fill more air, then the balloon will burst after an extent. This happens because air exerts pressure. We have also experienced the movement of fringes of windows and doors of our houses when wind blows in a high speed. This also happens because air exerts pressure.<\/span><\/p>\n

4. You want to buy a house. Would you like to buy a house having windows but no ventilators? Explain your answer.<\/strong><\/span><\/p>\n

Answer –\u00a0 <\/strong>A house having windows but no ventilators should not be bought. This is because warm air is lighter than cold air and therefore, it goes up. This warm air can go outside the house mostly through ventilators. If there are no ventilators, then the warm air cannot go outside easily.<\/span><\/p>\n

5. Explain why holes are made in hanging banners and hoardings.<\/strong><\/span><\/p>\n

Answer – <\/strong><\/span>Holes in the banners and hoardings helps air to pass through it. Hence, banner can withstand the pressure of the air and remains intact.<\/span><\/p>\n

6. How will you help your neighbours in case cyclone approaches your village\/town?<\/strong><\/span><\/p>\n
