Consider the following statements about Karst Topography
- It is majorly formed by metamorphic rocks.
- It is found in the Himalayas and Vindhya region in India.
- Stalactite and Stalagmite are examples of Karst landforms.
How many of the above statements are correct?
Correct
Solution (b)
Statement 1 Statement 2 Statement 3 Incorrect Correct Correct Karst Topography is majorly formed by sedimentary rocks. It is found in the Himalayas and Vindhya region in India. Stalactite and Stalagmite are examples of Karst landforms. The water containing limestone in solution, seeps through the roof in the form of a continuous chain of drops. A portion of the roof hangs on the roof and on evaporation of water, a small deposit of limestone is left behind contributing to the formation of a stalactite, growing downwards from the roof. The remaining portion of the drop falls to the floor. This also evaporates, leaving behind a small deposit of limestone aiding the formation of a stalagmite, thicker and flatter, rising upwards from the floor.
Other Karst Landforms – Sinking Creeks/Bogas, Arch, Sink Hole and Cavern.

Question 12 of 35
12. Question
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?
- Many slopes in Nilgiris are steeper with almost vertical cliffs and escarpments.
- Mechanical weathering due to temperature changes and ranges is pronounced in this region.
- They are mostly made up of sedimentary rocks and unconsolidated and semi-consolidated deposits.
- They receive heavy amounts of rainfall over short periods.
How many of the above statements are correct?
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. Incorrect

Question 14 of 35
14. Question
Which of the following characteristic feature of fluvial Erosional landforms is/are correctly matched?
- Gorges: They are formed due to active downcutting of the valleys through the mechanism of pothole drilling during the youth stage.
- Potholes: They are generally formed in coarse-grained rocks such as sandstones and granites.
- Waterfalls: They are formed due to variations in the relative resistance of rocks.
How many of the above pairs are correctly matched?
Correct
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. Incorrect

Consider the following statements about glaciers
- Erosion by glaciers is huge because of friction caused by sheer weight of the ice sheet.
- The cirques are found at the heads of glacial valleys, mostly having tarn lakes.
- Moraines are long ridges of deposits of glacial till
How many of the above statements are correct?
Correct
Solution (c)
Statement 1 Statement 2 Statement 3 Correct Correct Correct 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 Incorrect

Question 16 of 35
16. Question
Which of the following statements defines the significance of the process of weathering?
- Weathering provides regolith for the formation of soil.
- Weathering produces concentrations of valuable mineral ores of iron, manganese, tin, etc.
- Weathering aids mass wasting and reduction of relief.
How many of the above statements are correct?
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. Incorrect

Question 17 of 35
17. Question
Which of the following factors act as the requisite for the mass movement?
- Decrease in gradient and height of slopes.
- Removal of material from over the original slope surfaces.
- Saturation and lubrication of slope materials.
How many of the above statements are correct?
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. Incorrect

Question 18 of 35
18. Question
Match the following
Erosional Landform Agents
- Serrated ridges – Groundwater
- Deflation Hollows – Glacier
- Sink Holes – Wind
How many of the above pairs are correctly matched?
Correct
Solution (d)
Statement 1 Statement 2 Statement 3 Incorrect Incorrect Incorrect 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. Incorrect
Solution (d)
Statement 1 Statement 2 Statement 3 Incorrect Incorrect Incorrect 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. -
Question 19 of 35
19. Question
Arrange the following coastal landforms in the increasing order of erosion level they are subjected to
- Stacks
- Sea caves
- Sea arches
Select the correct answer using the codes given below
Correct
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

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?
Correct
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
