Question 14 Marks
Read the passage given below and answer the following questions.
Air pressure is defined as the pressure exerted by the weight of air on the Earth's surface. As we go up the layers of atmosphere, the pressure falls rapidly. The air pressure is highest at sea level and decreases with height. Horizontally the distribution of air pressure is influenced by temperature of air at a given place. In areas where temperature is high, the air gets heated and rises. This creates a low-pressure area. Low pressure is associated with cloudy skies and wet weather. In areas having lower temperature, the air is cold. It is therefore heavy. Heavy air sinks and creates a high pressure area. High pressure is associated with clear and sunny skies. The air always moves from high pressure areas to low pressure areas.
(i) Which of the following factor influences the horizontal distribution of air pressure, as mentioned in the passage?
(a) Altitude changes
(b) Atmospheric layers
(c) Temperature variations
(d) Wind patterns
(ii) How is formation of a low-pressure area related to the temperature of the air in a given location?
(a) High temperatures leads to low pressure
(b) Low temperatures create low pressure
(c) High temperatures result in high pressure
(d) Low temperatures cause high pressure
(iii) In which atmospheric layer does air pressure fall rapidly with increasing height?
(a) Stratosphere
(b) Troposphere
(c) Mesosphere
(d) Thermosphere
(iv) What weather condition is associated with a low-pressure area, according to the passage?
(a) Stormy weather
(b) Clear and sunny skies
(c) Overcast conditions
(d) Intense precipitation
