Prologue

  • 14 out of 100 MCQs in CSAT 2013 were from Geography. Last year it was 11.
  • Majority of the question can be solved directly from standard reference books/sources for Geography viz.
    • NCERT
    • NIOS
    • General studies Manual
    • Indian Geography by Majid Hussein
  • Within Indian geography, agro related Qs. receive attention, just like last year.
  • Within Physical geography, ocean, temperature related Qs, just like last year.
  • World Geography continues to receive low-priority (Although world geography should not be completely ignored in preparation because Mains 2013 does contain topics from World Geography.)
  • Nothing from current affairs.

Geography: Internal breakup

World Geography (2Qs)

Atlas Mountain Ranges

1.  Which one of the following pairs is correctly matched?

  1. Abyssinian Plateau : Arabia
  2. Atlas Mountains : North-Western Africa
  3. Guiana Highlands : South-Western Africa
  4. Okavango Basin : Patagonia

In the school atlas, check the physical map of Africa. You’ll see Atlas mountain range in the Top-left corner (=north Western) => Answer B is correct.

Regarding other choices:

  1. Abyssinian plateau is in Ethiopia (in Africa)
  2. Guiana Highland= In South America
  3. Okavango basin/swamp= In Southern part of in Africa.

Hence final answer (B) Atlas Mountains : North-Western Africa.

Nomadic herders

2. “Climate is extreme, rainfall is scanty and the people used to be nomadic herders.” The above statement best describes which of the following regions?

  1. African Savannah
  2. Central Asian Steppe
  3. North American Prairie
  4. Siberian Tundra

let’s consider the options

African Savannah

Doesn’t fit the description of “Climate is extreme, rainfall is scanty”

Siberian Tundra?

  • as per NIOS Geography material, chapter.16 Life In The High Latitudes
  • Extreme climate= yes
  • Low precipitation =yes.
  • Nomadic life = yes
  • but they’re not nomadic “herders”. Their primary occupation is hunting and fishing.

Central Asian Steppe

  • as per NIOS Geography material, chapter.15 Life In The Mid Latitudes
  • extreme climate= yes
  • low precipitation =yes.
  • Nomadic life= yes. The mid-latitude (Central Asian) grassland were once home to pastoral nomads like Kirgiz, Kazakh and Kalmuks.

North American Prairie?

  • as per NIOS Geography material, chapter.15 Life In The Mid Latitudes
  • extreme climate= yes
  • low precipitation =yes.
  • nomadic life? = No. The farmers here use mechanized equipment and do wheat cultivation on large scale.

Hence answer B) Central Asian Steppe

Indian geography (6Qs)

Physical Geography of India (Narmada) 1
Minerals and Energy related 2
Agro related 2
Human Geography (Tribals) 1
Total 6

Narmada

Q. The Narmada river flows to the west, while most other large peninsular rivers flow to the east. Why?

  1. It occupies a linear rift valley.
  2. It flows between the Vindhyas and the Satpuras.
  3. The land slopes to the west from Central India.

Select the correct answer using the codes given below.

  1. 1 only
  2. 2 and 3
  3. 1 and 3
  4. None
  • Refer to NCERT 11th standard, Geography, 3rd chapter, page number 27. It says Narmada and Tapi flow through rift valleys caused due to the upheaval of Himalayas.
  • Also it is given in the last line of the page as it flows through the rift valley with the Satpura in south and Vindhyas in the north. But there is no option for 1 & 2. We can consider maybe that flowing between the ranges may not cause the river to flow west and it is only a fact.
  • Refer to NCERT Class 9 Contemporary India textbook, chapter 2, page number 10. It gives the contours of the Indian physical systems. We can see that Narmada is flowing through the area where the land is not sloping towards the west from central India, but it is flowing west because of the rift valleys only.

Map Narmada elevation
Hence answer (A) Only 1

Mica, Petrol and Gas

1. Consider the following statements:

  1. Natural gas occurs in the Gondwana beds.
  2. Mica occurs in abundance in Kodarma.
  3. Dharwars are famous for petroleum.

Which of the statements given above is/are correct?

  1. 1 and 2
  2. 2 only
  3. 2 and 3
  4. None

Refer to level 2 Q6 in Pearson’s General Studies Manual (2011), all three statements are directly lifted.
http://books.google.co.in/books?id=WuBFs6yFRwcC&pg=RA2-PA35&lpg=RA2-PA35
And as per Thorpe (author of the Manual) only Mica-Kordema Statement is correct.
http://books.google.co.in/books?id=WuBFs6yFRwcC&pg=RA2-PA55&lpg=RA2-PA35&ots=r3dPt0txsL

Statement T/F? Why?
  1. Natural gas occurs in the Gondwana beds.
False
  • Gondwana beds = coal deposits (and not natural gas.) (Majid)
  1. Mica occurs in abundance in Kodarma.
True
  • TMH General Studies manual, Ch. Indian and World Geography, page 127
  • Kodarma mines in Jharkhand are one of the important mica producing areas
  • Another reference is Indian Geogrpahy, Majid Hussain Page 7.18 The main center of mica production in Jharkhand and Bihar are Kodarma, Dhorhakola.
  1. Dharwars are famous for petroleum.
False
  • Dharwar = district in Karnataka. Not related with petroleum.

Hence answer: (B) only 2.

Coal, Indian

Which of the following is / are the characteristic/ characteristics of Indian coal?

  1. High ash content
  2. Low sulphur content
  3. Low ash fusion temperature

Select the correct answer using the codes given below.

  1. 1 and 2 only
  2. 2 only
  3. 1 and 3 only
  4. 1, 2 and 3

Standard reference books (NCERT, NIOS, TMH, Majid) are silent about low ash fusion temperature of Indian coal, hence time to dig internet.
