The Nilgiris along the west coast are relatively tectonically stable as compared to the Himalayas but, still, debris avalanches and landslides occur though not as frequently as in the Himalayas, in these hills. Why?
How many of the above statements are correct?
Solution (c)
Statement 1 | Statement 2 | Statement 3 | Statement 4 |
Correct | Correct | Incorrect | Correct |
Many slopes are steeper with almost vertical cliffs and escarpments in the Western Ghats and Nilgiris. They have almost a vertical elongation where ‘snowballing’ of debris avalanches and landslide can easily happen. | Mechanical weathering due to temperature changes and ranges is pronounced due to the western ghats proximity towards the equator where it receives high temperature and high Rainfall.
This causes solifluction which may sometimes result in landslides as well. |
In India, debris avalanches and landslides occur very frequently in the Himalayas because the Himalayas are tectonically active. They are mostly made up of sedimentary rocks and unconsolidated and semi-consolidated deposits. The slopes are very steep.
The Nilgiris are mainly composed of metamorphic rocks like gneiss and crystalline schist. |
They receive a heavy amount of rainfall over a short period. Most of the rainfall received in the area is mostly in the Monsoon season itself. |

Solution (c)
Statement 1 | Statement 2 | Statement 3 |
Correct | Correct | Correct |
Gorges are formed due to active downcutting of the valleys through the mechanism of pothole drilling during the youth stage of the fluvial cycle of erosion.
Gorges are also formed due to the recession of waterfalls. Most of the Himalayan Rivers have carved out deep and narrow gorges. |
The kettle-like small depressions in the rocky beds of the river valleys are called potholes which are usually cylindrical in shape. Potholes are generally formed in coarse-grained rocks such as sandstones and granites. | Waterfalls form as streams flow from soft rock to hard rock. This happens both laterally (as a stream flows across the earth) and vertically (as the stream drops in a waterfall). In both cases, the soft rock erodes, leaving a hard ledge over which the stream falls. This happens due to variations in the relative resistance of rocks. |

Masses of ice moving as sheets over the land or as linear flows down the slopes of mountains in a broad trough like valleys are called glaciers. The movement of glaciers is slow unlike water flow. The erosion by glaciers is tremendous because of friction caused by sheer weight of ice. | Cirque is the most common of landforms in glaciated mountains. The cirques are often found at the head of glacial valleys. A lake of water is usually formed within the cirque. This lake is known as Tarn Lake. | Moraines are long ridges of deposits of glacial till. When these deposits are at the end of a glacier, they are called Terminal moraines and when they are deposited on both sides, they are called Lateral moraines. When lateral moraines of two glaciers join together, they form Medial moraines. When the lateral moraines of both sides of a glacier join together, it forms a horseshoe shape. Ground moraines are deposits left behind in areas once covered by a glacier |

Which of the following statements defines the significance of the process of weathering?
How many of the above statements are correct?
Solution (c)
Statement 1 | Statement 2 | Statement 3 |
Correct | Correct | Correct |
It converts bedrock into regolith and soil. Regolith is also notable for being the basic source of the inorganic part of the soil. The importance of soil which indirectly supports all animal forms of life in the form of vegetation cannot be overemphasized.
Weathering creates raw material that becomes sediments and sedimentary rocks- loosens to individual minerals, attack and alter individual minerals and solution. It forms economic deposits/ importance in engineering projects. Weathering breaks rocks into their mineral components. It also creates new compounds through chemical changes. |
During the prolonged period, the weathering processes produce concentrations of valuable mineral ores of iron, manganese, tin, aluminium, uranium etc. For example, by chemical weathering soluble bases and even silica are removed, leaving behind increasingly rich residual concentrations of metallic oxides.
This occurs under humid tropical climatic conditions as part of the lateralization process. |
Weathering processes are responsible for breaking down the rocks into smaller fragments and preparing the way for the formation of not only regolith and soils but also erosion and mass movements. |

Which of the following factors act as the requisite for the mass movement?
How many of the above statements are correct?
Solution (b)
Mass Movement is the movement of masses of bodies of mud, bedrock, soil, and rock debris, which commonly happen along steep-sided hills and mountains because of the gravitational pull.
Gravity exerts its force on all matter, both bedrock and the products of weathering.
Statement 1 | Statement 2 | Statement 3 |
Incorrect | Correct | Correct |
In order for Mass Movements to happen, there has to be an increase in the gradient and height of slopes. This causes more debris to be attracted downwards. | If there is a removal of material or load from over the original slope surfaces. The debris from higher in the relief gets attracted downwards due to gravitational attraction thereby triggering Mass movement. | Saturation and lubrication of slope materials happen because of overloading due to heavy rainfall, This creates loosely packed mud and debris movement down the slope of the hills. |

Serrated Ridges: Horns form through headward erosion of the cirque walls.
If three or more radiating glaciers cut headward until their cirques meet, high, sharp-pointed and steep-sided peaks called horns form. The divides between cirque side walls or head walls get narrow because of progressive erosion and turn into serrated or saw-toothed ridges sometimes referred to as arêtes with very sharp crests and a zig-zag outline. |
Deflation Hollows: Weathered mantle from over the rocks or bare soil, gets blown out by the persistent movement of wind currents in one direction. This process may create shallow depressions called Deflation hollows | Sinkholes: Small to medium-sized rounded to sub-rounded shallow depressions called swallow holes forms on the surface of rocks like limestone by the action of the solution. A sinkhole is an opening more or less circular at the top and funnel-shaped towards the bottom. |

Arrange the following coastal landforms in the increasing order of erosion level they are subjected to
Select the correct answer using the codes given below
Solution (b)
The erosion and deposition of the sea waves give rise to coastal landforms.
Sea waves continuously strike at the rocks which leads to the development of cracks. Over time they become larger and wider. Thus, hollow caves are formed on the rocks. They are called sea caves. As these cavities become bigger and bigger only the roof of the caves remain, thus forming sea arches. Further, erosion breaks the roof and only walls are left. These wall-like features are called stacks

Solution (b)
The challenges in making the Indian rupee an international currency:
60 percent of the employees of a company are women and 75% of the women earn 20000 or more in a month. Total number of employees who earns more than 20000 per month in the company is 60 percent of the total employees. What fraction of men earns less than 20000 per month?
Solution (a)
Let total employees are 100 males = 40 and females = 60
75% of women earn 20000 or more in a month = 75/100 x 60 = 45
Thus, 45 women earns more than 20000
Total 60 employee earns more than 20000 per month
So number of males earns more than 20000 is = 60 – 45 = 15
∴number of male employees who earn less than 20000 per month = 40 – 15 = 25
so fraction = 25/40 = 5/8
Solution (a)
Let total employees are 100 males = 40 and females = 60
75% of women earn 20000 or more in a month = 75/100 x 60 = 45
Thus, 45 women earns more than 20000
Total 60 employee earns more than 20000 per month
So number of males earns more than 20000 is = 60 – 45 = 15
∴number of male employees who earn less than 20000 per month = 40 – 15 = 25
so fraction = 25/40 = 5/8
A truck covers a distance of 376 km at a certain speed in 8 hours. How much time would a car take at an average speed which is 18 kmph more than that of the speed of the truck to cover a distance which is 14km more than that travelled by the truck?
Solution (b)
Speed of truck = Distance covered time = 376/8 = 47 kmph
Now, speed of car = speed of truck + 18 = 47 + 18 = 65 kmph
Distance travelled by car = 376 + 14 = 390 km
Time taken by car = Distance covered speed = 390/65 = 6 hours
Solution (b)
Speed of truck = Distance covered time = 376/8 = 47 kmph
Now, speed of car = speed of truck + 18 = 47 + 18 = 65 kmph
Distance travelled by car = 376 + 14 = 390 km
Time taken by car = Distance covered speed = 390/65 = 6 hours
A teacher conducted a test is his class. Among the students who passed the test, Minakshi was ranked 16th from the top and 29th from the last. Six boys did not participate in the test and five students failed the test. How many students were there in the class?
Solution (d)
Number of students ahead of Minakshi = 15
Number of students behind Minakshi = 28
Total number of students who passed the test = 15 + 28 + 1 = 44
Total number of students in the class = Students who passed the test + Students who failed the test +
Students who did not appear for the test = 44 + 6 + 5 = 55
Solution (d)
Number of students ahead of Minakshi = 15
Number of students behind Minakshi = 28
Total number of students who passed the test = 15 + 28 + 1 = 44
Total number of students in the class = Students who passed the test + Students who failed the test +
Students who did not appear for the test = 44 + 6 + 5 = 55
A boy is asked to list all the permutations of the letters of the word EDUCATION such that all the vowels come at the beginning of the word. How many words does the boy list?
Solution (c)
Consonants in the word D, C, T, N = 4 consonants
Vowels in the word = E, U, A, I, O = 5 vowels
All the vowels should come in the beginning of the word.
Number of ways of rearranging 5 vowels = 5! = 120
Number of ways of rearranging 4 consonants = 4! = 24
Number of words in the list = 120 × 24 = 2880
Solution (c)
Consonants in the word D, C, T, N = 4 consonants
Vowels in the word = E, U, A, I, O = 5 vowels
All the vowels should come in the beginning of the word.
Number of ways of rearranging 5 vowels = 5! = 120
Number of ways of rearranging 4 consonants = 4! = 24
Number of words in the list = 120 × 24 = 2880
A child is playing with the chess board. He has 5 identical pawns with him. He places one pawn in one black box, second pawn in second black box and so on. In how many different ways can he place the 5 pawns in 5 different black boxes?
Solution (c)
5 identical pawns are to be placed in 5 different boxes.
The total number of black boxes on the chess board = 64/2 = 32
Now, all these 32 black boxes are different. So, the problem reduces to choosing 5 different objects from
a set of 32 objects.
Number of ways of selecting 5 boxes out of 32 boxes = 32C5
