MCQ Chapter 4 Geography Class 7 Maharashtra Board MCQ For All Chapters – Geography Class 7Air Pressure 1. What does air exert on the surface of the Earth?No pressureOnly heatPressureMagnetic forceQuestion 1 of 202. Which of the following factors influence air pressure?Temperature, altitude, and water vapourOnly temperatureOnly altitudeAir humidity onlyQuestion 2 of 203. Why does air pressure decrease with increasing altitude?Air becomes denserAir becomes thinnerTemperature increasesMore water vapour is presentQuestion 3 of 204. What happens to a flying lantern when the air inside it gets heated?It falls downIt remains stationaryIt moves upIt burstsQuestion 4 of 205. What happens to air pressure when the temperature increases?It decreasesIt increasesIt remains constantIt becomes unstableQuestion 5 of 206. What is the latitudinal extent of the Equatorial Low-Pressure Belt?0° to 5° North and South25° to 35° North and South55° to 65° North and South80° to 90° North and SouthQuestion 6 of 207. Why do mid-latitudinal high-pressure belts form?Due to air heating upDue to cold air descendingDue to winds moving upwardsDue to ocean currentsQuestion 7 of 208. Why do hot deserts form in high-pressure belt areas?Due to strong windsDue to heavy rainfallDue to dry descending airDue to lack of sunlightQuestion 8 of 209. In which regions do sub-polar low-pressure belts form?5° North and South25° to 35° North and South55° to 65° North and South80° to 90° North and SouthQuestion 9 of 2010.
