Solution: (a)
Pune is on the leeward side of the western ghats and so lies on a rain shadow area. The south west monsoon empties all moisture on the windward side of the mountain range and reaches Pune with less moisture after crossing the mountain range. But Mumbai lies on the windward side and hence experiences heavy rainfall.
Which of the following does not have an influence over the climate in India?
(a) Monsoons
(b) Ocean currents
(c) Nearness to equator
(d) Presence of Indian ocean
Solution: (b)
India’s geography and geology are climatically pivotal: the Thar Desert in the northwest and the Himalayas in the north work in tandem to effect a culturally and economically break-all monsoonal regime. As Earth’s highest and most massive mountain range, the Himalayan system bars the influx of frigid katabatic winds from the icy Tibetan Plateau and northerly Central Asia. Most of North India is thus kept warm or is only mildly chilly or cold during winter; the same thermal dam keeps most regions in India hot in summer. Ocean current do not any role in the climate of India.
Which one of the following is the wettest place in India?
(a) Mahabaleshwar
(b) Cherrapunji
(c) Udhagamandalam
(d) Mawsynram
Solution: (d)
Mawsynram is a village in the East Khasi Hills district of Meghalaya state in north-eastern India, 65 kilometers from Shillong. It is reportedly the wettest place on Earth, with an annual rainfall of 11,872 millimetres. According to the Guinness Book of World Records Mawsynram received 26,000 millimetres (1,000 in) of rainfall in 1985. Mawsynram is located about 16 km west of Cherrapunji, on the Khasi Hills.
Which one of the following coasts of India is most affected by violent tropical cyclones?
(a) Malabar
(b) Andhra
(c) Konkan
(d) Gujarat
Solution: (b)
The frequency of severe cyclonic storms is maxi mum for Andhra Pradesh while that of cyclone is maximum for Orissa. Considering west coast only, Gujarat is most vulnerable. The average annual frequency of tropical cyclones in the north Indian Ocean (Bay of Bengal and Arabian Sea) is about 5 (about 5-6 % of the Global annual average) and about 80 cy clones form around the globe in a year. The frequency is more in the Bay of Bengal than in the Arabian Sea, the ratio being 4:1.
Which one of the following is the driest region in India?
(a) Telengana
(b) Marwar
(c) Vidarbha
(d) Marathwada
Solution: (b)
Marwar is a region of southwestern Rajasthan state in western India. It lies partly in the Thar Desert which is the driest region of India. It includes the present-day districts of Barmer, Jalore, Lakshman Nagar, Jodhpur, Nagaur, and Pali. This desert tract, nicknamed Marwar or Marusthali – the Land of Death, lives up to its name with its scorching heat, thorny cactus and scrub, and scanty water.
Western disturbances cause rainfall in the following Indian states during winter
(a) Punjab and Haryana
(b) Madhya Pradesh and Uttar Pradesh
(c) Kerala and Karnataka
(d) Bihar and West Bengal
Solution: (a)
The term ‘Western Disturbance’ is used to describe an extra tropical storm, which brings winter rain and sometimes snow to the northwestern parts of the India. When the Western Disturbance moves across northwest India before the onset of monsoon, a temporary advancement of monsoon current appears over the states including Punjab, Uttar Pradesh, Jammu and Kashmir etc. When it passes across north India, it helps to increase monsoon activity over Punjab and Uttar Pradesh.
Tropical cyclones in the Bay of Bengal are most frequent during
(a) October–November
(b) May–June
(c) January–February
(d) March–April
Solution: (a)
They are most frequent during the summer (June September) over the northern part of the Bay of Bengal and over Eastern parts of Arabian Sea. They are more frequent in the Bay and in Arabian Sea in the region between 6 degree North to 15 degree North during the pre-monsoon (March-May) and post-monsoon (October-November) seasons and are least frequent during the winter.
Which showers are favorable to the rabi crops in Punjab during winter?
(a) Showers caused by Jet streams
(b) Mango showers
(c) Showers caused by western disturbances
(d) Kal-Baisakhi
Solution: (c)
Western Disturbance causes winter and pre monsoon season rainfall across northwest India. Winter months Rainfall has great importance in agriculture, particularly for the rabi crops. Wheat among them is one of the most important crops, which helps to meet India’s food security.
October and November months give more rainfall to:
(a) Malwa Plateau
(b) Chota Nagpur Plateau
(c) Eastern Hills
(d) Coromandal Coast
Solution: (d)
The Coromandal Coast of Tamil Nadu receives heavy rainfall from the retreating monsoon winds as the retreating winds are moisture laden. It falls in the rain shadow of the Western Ghats, and receives a good deal less rainfall during the summer southwest monsoon, which contributes heavily to rainfall in the rest of India. The region averages 800 mm/year, most of which falls between October and December.
The burst of monsoons in the month of June brings rain to
(a) Kerala and Karnataka
(b) Kerala and the Southern coast of Tamil Nadu
(c) Kerala, Tamil Nadu, and parts of Andhra Pradesh
(d) Kerala, Tamil Nadu, and Karnataka
Solution: (b)
The burst of monsoons in the month of June brings rain to Kerala and Southern coast of Tamil Nadu.
