Physical Geography

1. Which one among the following statements is not correct?

  1. The plane of separation between the crust and mantle is known as Mohorovicic discontinuity
  2. The mantle contains more than two-third of the total material mass of the Earth
  3. The mantle is composed of the heaviest materials of the Earth
  4. The inner core of the Earth is in solid state

1st statement is correct. Moho=Crust-Mantle and Gutenburg=Mantle-Core. (THM GS Manual)

2nd statement is correct. Mantle contains more than two-third of the total material mass of the Earth. Correct (Encyclopedia of Earthquakes and Volcanoes  By Alexander E. Gates, David Ritchie, Page 73)

4th statement is correct. The outer core is in liquid state while the inner core is in solid state.Correct (NCERT GEOGRAPHY CLASS 11, CHAPTER 3)

So we are left with answer (C)

2. Hurricanes rarely form or move within 5 degrees of the equator, because

  1. Coriolis effect is weakest here
  2. Coriolis effect is strongest here
  3. it has low pressure
  4. it has high temperature

At the equator, the Coriolis force is zero and the wind blows perpendicular to the isobars. The low pressure gets filled instead of getting intensified. That is the reason why tropical cyclones are not  formed near the equator. (NCERT GEOGRAHPY CLASS 11, CHAPTER 10)

Answer is (A)

3. Whenever tropical cyclone moves to land, much of its severity is reduced due to

  1. its source of moisture is cut off
  2. friction over land kills tropical cyclone

which is correct?

  1. 1 only
  2. 2 only
  3. Both 1 and 2
  4. Neither 1 nor 2

…With continuous supply of moisture from the sea, the storm is further strengthened. (but) On reaching the land the moisture supply is cut off and the storm dissipates. (NCERT GEOGRAHPY CLASS 11, CHAPTER 10)

Answer (A) only 1 is correct.

4. Asteroid belt is situated between

  1. Mars and Jupiter
  2. Earth and Mars
  3. Jupiter and Saturn
  4. Venus and Earth

It is between Mars and Jupiter. (NCERT SCIENCE CLASS 8, CHAPTER 17, FIG 17.25)

Answer (A)

5. What do you call the total system of parallels and meridians that form a network of intersecting lines?

  1. Geographic pattern
  2. Geographic arrangement
  3. Geographic grid
  4. Geographic polygon

They form the basis for the geographical grid. A network of intersecting lines is drawn for the purpose of fixing the locations of different features. The grid consists of two sets of horizontal and vertical lines,  which are called parallels of latitudes and the meridians of longitudes. (NCERT class-11-Practical-Work-in-Geography, Chapter 3)

Answer (C)

6. Why does the Earth assume the shape of an oblate ellipsoid?

  1. The Earth’s rotation causes the Earth to bulge slightly at the equator and flatten at the poles
  2. The Earth’s rotation causes the Earth to bulge slightly at the poles and flatten at the equator
  3. The Earth’s revolution causes the Earth to bulge slightly at the equator and flatten at the poles
  4. The Earth’s revolution causes the Earth to bulge slightly at the poles and flatten at the equator

The rotation of the earth over its axis produces bulging at the equator. Hence, the actual shape resembles that of an oblate spheroid. NCERT class-11-Practical-Work-in-Geography, Chapter 3)

Answer is (A).

7. Which one among the following is a mechanically formed sedimentary rock?

  1. Salt rock
  2. Limestone
  3. Sandstone
  4. Gypsum

Depending upon the mode of formation, sedimentary rocks are classified into three major groups: (i) mechanically formed — sandstone, conglomerate, limestone, shale, loess etc. are examples; (NCERT GEOGRAHPY CLASS 11, CHAPTER 5)

Answer is (C)

  3. sir cyclone reduced coz of both reasons given in Question.so ans should be C

    sir u can check at wikipedia

  4. Sir ,
    @Env Questn :

    Biodiversity hotspots :now 3 B.H-S
    The Western Ghats and Sri Lanka
    The Eastern Himalayas


  5. physical geo q 3- trop cyclone correct answer c i:e both 1 and 2.

    source for 2nd stat to be true (wikipedia-tropical cyclone) copy-paste-

    “While tropical cyclones can produce extremely powerful winds and torrential rain, they are also able to produce high waves, damaging storm surge, and tornadoes. They develop over large bodies of warm water, and lose their strength if they move over land due to increased surface friction and loss of the warm ocean as an energy source.”

    1. the cyclone only loses its strength and does not get “killed”. And if you had followed the news about some recent cyclones/hurricanes, you would have seen that much of the destruction occured on the land/coastal areas and this wouldn’t have been possible if they had got “killed” after reaching the land. They eventually die, but gradually.

      1. As far as the the question, land is not equal to coastal area. As far as your interpretation of “killed”. killed = die, where’s the contradiction.

        1. i didn’t even say anything about contradiction and u just made it up! Kindly focus on what i had written-“they EVENTUALLY die, but GRADUALLY”, irrespective of UPSC’s answer. And wait.. what???!!! land isn’t equal to the coastal area???!!! means if i am standing on a beach, i could claim that i ain’t on land?? and if you meant water, kindly refer to the term continental shelf, which’s what a “watery/sumberged coastal area” is called/a part of. Now i know 2 things: 1st is that u didn’t study geography seriously and 2nd is that if the world ends on 21 DEC, your logic would be the cause. even if we restrict ourselves to the question, our common sense shouldn’t be confined to it. looks like you’ve had some shots too many of jazz and liquor. and yeah, land then must be equal to a rap song.

          1. Yep, man, my geography is pathetic that’s why I looked wikipedia. Now, if you look at another question of science in the same paper “phthalates “-it was lifted from wki.just look for “phthalates” entry in wiki and compare the answer options.(which is to suggest that UPSC simply lifts from wiki).

            One correction though, what i meant that land does not mean coastal area only(Forgot to add ‘only’ and it triggered you in action). You are making a difference between killed and “eventual but gradual death”(slightly abridged). Now let’s accept that there IS a difference…whats the cause, FRICTION, right!(wiki in support) OR truckload of geography books scattered all along the Coromandel Coast.

            Excess study leads to figurative logic, that’s why we make mistakes.No polemics.

  6. i fail to understand why wikipedia is considered as the ultimate source of information. 2nd statement was highly assertive, means by what i have seen in general and in upsc’c answer keys for csp, they tend to trick you into agreeing with the statements of such nature. these tread close to known facts but include one such line/word that takes the correctness away. i just hope that upsc gets cursed for making such questions. die upsc, die.

    my logic is more in the likes of commonsense and rationality than figurative and it’s upto your “figurative” imagination to comprehend for yourself what i really meant. adios comrade..

  7. thank you sir.
    your notes are amazing, and very narrative in nature, and the teats are also very insightful…..

  8. “7. Which one among the following is a mechanically formed sedimentary rock?

    Salt rock
    Depending upon the mode of formation, sedimentary rocks are classified into three major groups: (i) mechanically formed — sandstone, conglomerate, limestone, shale, loess etc. are examples; (NCERT GEOGRAHPY CLASS 11, CHAPTER 5)

    Answer is (C)”

    Limestone is also in the options and you said in the explanation that it is also a mechanically formed sedimentary rock.

  9. According to the latest data by Planning Commission the EPI of Andhra Pradesh is highest followed by Sikkim and Himachal….. Delhi is at the last.

  10. Hello Sir,

    I am preparing for CAPF (AC) exam which will be held on 20th Oct this year. I am taking previous years’ sample paper and still not getting good score. As I found myself very weak at general awareness, can you please suggest me how my preparation should be, so that I can score well in my final exam? That would be really great if you can suggest some material also.

    Highly obliged!!

  11. Thanks mural its really helping us on preparation.
    & i would like to know do u have any Page on CDS EXAM and their previous paper & results….
