Geography Landforms and their evolution Question for UPSC | HCS | RAS Q1. Consider the following statements/निम्नलिखित कथनों पर विचार करें
  1. The zones of permeable rocks which are fully filled with water are called as the Zones of Saturation/पारगम्य एवं   छिद्रयुक्त चट्टानों के क्षेत्र  या क्षितिज जो पूरी तरह से पानी से परिपूर्ण  उन्हें संतृप्ति के क्षेत्र कहा जाता है।
  2. Water tables are the marks which show the upper surface of saturated zones of the groundwater/वह चिह्न जो भौम जल के  संतृप्ति क्षेत्र की ऊपरी सतह को दर्शाता हैं उन्हें जल स्तर कहा जाता है |
  3. Erosion of rocks is caused by the downward movement of water only/जल का अपरदन चट्टानों के क्षैतिज प्रवाह का ही कारण है |
Which of the above statement/s is/are correct/इनमे से कौन सा कथन सही है
  • Only 3
  • 1 and 2
  • 2 and 3
  • 1,2,3
[showhide type=”links1″ more_text=”Show Answer” less_text=”Hide Answer”] Ans. B is correct.
  • Statement 1 is correct  The zones of permeable rocks which are fully filled with water are called as the Zones of Saturation.
  • Statement 2 is correct Water tables are the marks which show the upper surface of saturated zones of the groundwater.
  • Statement 3 is not correct It is the downward and horizontal movement of water which causes the rocks to erode.

  1. When most of the surfaces of limestone are eaten by solution process, landforms resulted are called Lapies/जब चूनापत्थर के अधिकतर सतहों को विलयन प्रक्रिया द्वारा क्षतिग्रस्त कर दिया जाता है तो ये लेपिस कहलाते है |
  2. Limestone landforms produced by groundwater through solution and deposition is called Karst topography/चूनापत्थर स्थलरूप जो भौम जल द्वारा घुलनप्रक्रिया और उसके निक्षेपण प्रक्रिया से बने हो उन्हें  कार्स्ट स्थलाकृति का नाम दिया गया है |
  3. When as sinkhole is formed solely through the process of solution, it is called as a solution sink./जब घोलरंध्र पूर्णतः घुलन प्रक्रिया के द्वारा निर्मित होते हैं तो उन्हें विलयन छिद्र  कहा जाता है |
Which of the above statement/s is/are correct/इनमे से कौन सा कथन सही है –

[showhide type=”links2″ more_text=”Show Answer” less_text=”Hide Answer”] Ans. D is correct.
  • Statement 1 is correct Lappies are the irregular grooves and ridges formed when most of the surfaces of limestone are eaten by solution process.
  • Statement 2 is correct Any limestone or dolomitic region showing typical landforms produced by the action of groundwater through the processes of solution and deposition is called Karst topography
  • Statement 3 is correct When as sinkhole is formed solely through the process of solution, it is called as a solution sink.

  2. Stalagmites  are calcium carbonate deposits hanging as icicles while Stalactites     rises up from the floor./स्टैलेगमाइट कैल्शियम कार्बोनेट के निक्षेप होते हैं जो हिमस्तम्भ के जैसे लटके  हुए होते हैं जबकि स्टैलैकटाइट फर्श से ऊपर की तरफ बढ़ते हैं |
  3. In India, Alpine   glaciers    are found in higher regions of the Himalayas ./भारत  में अल्पाइन ग्लेशियर हिमालय के उच्च क्षेत्रों में पाए जाते है |

  3. Ogives are dark colored wave crests and valleys of ice on glacier surfaces/ओजाइव काले रंग की चोटियां तथा घाटियां है जो हिमनद की सतह पर है |
Which of the above statement/s is/are correct ?/इनमे से कौन सा कथन सत्य है

  • Statement 1 is not correct The lowest limit of permanent snow or snow-field is called as the snowline.
  • Statement 2 is correct  Glaciers are the largest freshwater reservoirs on earth.
  •  Statement 3 is not correct Ogives are alternating wave crests and valleys (troughs) that appear as dark and light bands of ice on glacier surfaces.
[/showhide] Q5. Consider the following statements/निम्नलिखित कथनों पर विचार करें
