Subject : Geography (06 November 2023)
1. Consider the following pairs regarding wind circulation:
1. Ferrel Cell : Cell in the middle latitudes
2. Hadley Cell : Cell in the tropics
3. Polar Cell : Cell in the polar region
How many of the above pairs is/are correctly matched?
(a) Only one pair
(b) Only two pairs
(c) All three pairs
(d) None
Answer: (C)
Explanation: Circulations from the surface upwards and vice-versa are called cells. Such a cell in the tropics is called Hadley Cell. In the middle latitudes the circulation is that of sinking cold air that comes from the poles and the rising warm air that blows from the subtropical high. At the surface these winds are called westerlies and the cell is known as the Ferrel cell. At polar latitudes the cold dense air subsides near the poles and blows towards middle latitudes as the polar easterlies. This cell is called the polar cell. These three cells set the pattern for the general circulation of the atmosphere. The transfer of heat energy from lower latitudes to higher latitudes maintains the general circulation. Hence, all pairs are correctly matched.
2. Consider the following statements regarding Aravalli Ranges:
1. They are one of the oldest fold mountains of the world and the oldest in India.
2. They are aligned in north-west to south-east direction.
3. Luni, Banas and Sahibi rivers flow from the Aravalli ranges.
How many of the above statements is/are correct?
(a) Only one
(b) Only two
(c) All three
(d) None
Answer: (B)
Explanation: They are aligned in north-east to south-west direction. They run between Delhi and Palanpur in Gujarat. They are one of the oldest fold mountains of the world and the oldest in India. According to some geographers, one Branch of the Aravalis extends to the Lakshadweep Archipelago through the Gulf of Khambhat and the other into Andhra Pradesh and Karnataka. Three major rivers and their tributaries flow from the Aravalli, namely Banas and Sahibi rivers which are tributaries of Yamuna, as well as Luni River which flows into the Rann of Kutch. Hence, statement 2 is not correct.
3. Consider the following statements regarding Intertropical Convergence Zone (ITCZ):
1. The ITCZ is a zone of convergence at the thermal equator where the trade winds meet.
2. It is a low-pressure belt and migrates with the changing position of the thermal equator.
Which of the above statements is/are correct?
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Answer: (C)
Explanation: The ITCZ is a zone of convergence at the thermal equator where the trade winds meet and it is a zone where air tends to ascend. It is a low-pressure belt and migrates with the changing position of the thermal equator. The movement of the thermal equator shifts the belts of planetary winds and pressure systems to the north and to the south annually. Hence, both statements are correct.
4. Consider the following statements regarding Temperature Inversion:
1. Temperature Inversion is a situation where the temperature decreases with increasing altitude.
2. A long summer night with cloudy skies and moving air is ideal situation for inversion.
Which of the above statements is/are correct?
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Answer: (C)
Explanation: Normally, temperature decreases with increase in elevation. It is called normal lapse rate. At times, the situations are reversed and the normal lapse rate is inverted. It is called Inversion of temperature. Inversion is usually of short duration but quite common nonetheless. A long winter night with clear skies and still air is ideal situation for inversion. The heat of the day is radiated off during the night, and by early morning hours, the earth is cooler than the air above. Hence, both statements are correct.
5. It is white or colourless and used in radio and radar. It is one of the most important components of granite. Which of the following mineral is associated with the above feature?
(a) Pyroxene
(b) Quartz
(c) Feldspar
(d) Mica
Answer: (B)
Explanation: Quartz is one of the most important components of sand and granite. It consists of silica. It is a hard mineral virtually insoluble in water. It is white or colourless and used in radio and radar. It is one of the most important components of granite. Hence, option (b) is correct.
