IAS Exam: Prelims Geography Goh Cheng Leong Questions: Landforms of Glaciation

Jan 21, 2016 15:43 IST

    Geography Subject for the Civil Services Exam is a very important component for the IAS Preparation and hence the candidates gave special emphasis on Geography. Goh Cheng Leong is one of the essential books for IAS Exam Preparation. Here we are covering the whole Goh CHeng Leong book through the Multiple Choice Questions:

    Q.1. Consider the following statements

     1. Icebergs while afloat in float in sea only 1/3rd is visible above surface.

     2. In equator snowline is at higher altitudes from sea level compared to Polar Regions.

    Select the correct answer from the following codes

    a.Only 1
    b.Only 2
    c.Both 1 and 2
    d.Neither 1 nor 2

    Answer: b

    Explanation:  snowline is at lower altitudes in polar and temperate regions and in equator it is at higher altitudes from sea level. For example from sea level in polar regions to 9000ft in Alps and 17000 ft in equator.

    Q.2. Which of the following is true about glacier?

    1. Glaciers are narrow at source but broadest down the hill.

    2. Glaciers move because it is in liquid state.

    3. The rate of movement is greatest in the side and bottom of glacier than middle.

    Select the correct answer from the following codes

    a.Only 1
    b.Only 2 and 3
    c.1,2 and 3
    d.None

    Answer: d

    Explanation:  Though glaciers are not in liquid state, due continual pressure from accumulated snow above, it moves. The rate of movement is greatest in middle due little obstruction. The sides and bottom are held back by little friction in valley.

    Q.3. consider the following statements?

    1. Glaciations give rise to erosional features in highlands.

    2. Glaciations give rise to depositional features in lowlands.

    3. Erosional and depositional features are mutually exclusive in Glaciations.

    Select the correct answer from the following codes

    a.Only 1
    b.Only 1 and 2
    c.Only 2 and 3
    d.1,2 and 3

    Answer: b

    Explanation: Erosional and depositional features are not mutually exclusive in Glaciations, because glacier plays a combined role of Erosional, depositional and transportation throughout its course.

    Q.4. Which of the following determines rate of erosion of glaciers ?

    1. Velocity of flow

    2. Weight of Glacier

    3. Gradient of Slope

    4. Geological structure of valley

    Select the correct answer from the following codes

    a.Only 2 and 3
    b.Only 1 and 4
    c.Only 1, 3  and 4
    d.1,2 ,3 and 4

    Answer: d

    Explanation: The rate of erosion of glaciers depend on Velocity of flow, Weight of Glacier, Gradient of Slope, Geological structure of valley

    Q.5. Consider the following statements

     1. Glaciers in main valley is eroded less than glaciers in tributary valley.

     2. Hydro electric power generation is feasible only in main valley glaciers.

    Select the correct answer from the following codes

    a.Only 1
    b.Only 2
    c.Both 1 and 2
    d.Neither 1 nor 2

    Answer: d

    Explanation:  Main valley glaciers are eroded much more rapidly than the tributary valley as it contains much larger glaciers. Tributary valleys also form a natural head of water for generating hydro electric power.

    Q.6. Consider the following statements

     1. Glacial influences are always unfavourable on man’s economic activities.

     2. Old glacial lake bed support heavy cropping.

    Select the correct answer from the following codes

    a.Only 1
    b.Only 2
    c.Both 1 and 2
    d.Neither 1 nor 2

    Answer: b

    Explanation:  Glacial influences on man economic activities are both favourable and unfavourable depending on intensity of glaciations, and relief of region.

    Q.7.  The economic benefits of glaciated landforms include?

    1. Moulds for metal castings

    2. Hydro electric power

    3. Highway and building construction

    Select the correct answer from the following codes

    a.Only 1
    b.Only 1 and 2
    c.Only 2 and 3
    d.1,2 and 3

    Answer: d

    Explanation: It also supports tourism.

    Q8. Which of following glacier is not located in Karakoram Range?
    a.    Siachen
    b.    Hipsar
    c.    Baltoro
    d.    Sonapani
    Ans: d

    Explanation: The Sonapani glacier is the longest glacier of Pir-Panjal which is located in the Chandra Valley of Lahul and Spiti region.
