Subject : Geography (08 November 2023)
1.Consider the following statements:
1.Fog is a phenomenon of small droplets remaining suspended in the air.
2. Western disturbances along the extreme northern India inhibits the development of fog over Delhi-Haryana-Punjab belt.
3. Clear sky conditions accompanied by calm winds during the day allows the fog to persist for longer than normal duration.
How many of the above statements is/are correct?
(a) Only one
(b) Only two
(c) Only three
(d) All four
Answer: (B)
Explanation: Fog is a phenomenon of small droplets remaining suspended in the air. Fog develops normally during late evening, night or early morning hours of the day, severely affecting visibility. Foggy conditions prevail over the plains of north India during the winter season and can prolong for days and sometimes even for weeks. Fog develops over Delhi-Haryana-Punjab belt due to the passing of an active western disturbance, which cause light rain and bring fresh moisture over these regions. Clear sky conditions accompanied by calm winds during the day allows the fog to persist for longer than normal duration. Hence, statement 2 is not correct.
2.Consider the following stages of Coal formation:
1.Peat deposits
2. Bituminous coal
3. Lignite
4. Anthracite coal
Arrange the above in chronological order:
(a) 1-2-3-4
(b) 1-3-4-2
(c) 1-3-2-4
(d) 1-4-3-2
Answer: (C)
Explanation: As organic material dies and is deposited in swamps or swampy lakes, the material undergoes bacterial and chemical changes to create peat deposits. Over millions of years, this peat gets buried under many layers of sediment the pressure and temperature of the peat increases. Gradually, the peat turns into lignite or brown coal, then sub-bituminous coal, bituminous coal, and finally hard anthracite coal. While coal is being formed, the decomposing organic material produces methane gas – the main component of natural gas – along with nitrogen and carbon dioxide. With the pressure of being buried under sediment, most of the methane stays trapped on the surface of the coal. Hence, option (c) is correct.
3.Consider the following statements:
1. Garo and Khasi hills are extensions of Purvanchals in Meghalaya forming water divide between Brahmaputra and Barak River.
2. Rajmahal Hills are formed from rocks dating from the Jurassic Period and named after the town of Rajmahal which lies to the east in the state of Jharkhand.
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: (B)
Explanation: Garo and Khasi hills are the extensions of peninsular part of the subcontinent. Along with the Karbi Anglong plateau, the Meghalaya plateau (comprising Garo, Khasi and Jaintia hills) is separated from the Chotanagpur plateau (part of peninsular india ) by Malda fault (in Bengal). Rajmahal Hills are formed from rocks dating from the Jurassic Period and named after the town of Rajmahal which lies to the east in the state of Jharkhand. Hence, statement 2 is correct.
4.Consider the following statements regarding the physiography of India:
1. The core of the Great Himalayan is made up of limestone rocks.
2. The trough of the Narmada River is interposed between the Vindhyan and the Satpura ranges.
3. The Deccan Plateau receives heavy rainfall throughout the year as it falls on the windward side of major hills of Central and Southern India.
How many of the above statements is/are correct?
(a)Only one
(b) Only two
(c) All three
(d) None
Answer: (A)
Explanation: Limestones can’t bear the heavy weight of Himalayas. The core is actually made of granite rocks. It is one of the rivers in India that flows in a rift valley, flowing west between the Satpura and Vindhya ranges. The Deccan Plateau is a large triangular plateau, bounded by the Vindhyas to the north and flanked by the Eastern and Western Ghats. This region is mostly semi-arid as it lies on the leeward side of both Ghats. Much of the Deccan is covered by thorn scrub forest scattered with small regions of deciduous broadleaf forest. Climate in the Deccan ranges from hot summers to mild winters. Hence, only statement 2 is correct.
5. Consider the following statements regarding Ravines in India:
1. Ravines in India are a geological feature formed millions of years ago when the peninsular plate pressed against the Himalayas.
2. Ravines are mostly found in the vicinity of the Vindhyas.
3. Ravines get aggravated by soil erosion.
How many of the above statements is/are correct?
(a) Only one
(b) Only two
(c) All three
(d) None
Answer: (C)
Explanation: Ravines in India are a geological feature formed millions of years ago when the peninsular plate pressed against the Himalayas. Almost all of India’s ravines are found in the vicinity of the Vindhyas, with over 60 per cent being in Uttar Pradesh, Madhya Pradesh, Gujarat and Rajasthan, as per the National Remote Sensing Centre, Hyderabad. However, ravines get aggravated by soil erosion, mostly caused by a flowing waterbody. The adjacent land gets eroded to form narrow depressions with sharp slopes. Over time, ravines widen, rendering land uncultivable and infertile with the erosion of the topsoil. Hence, all statements are correct.
