[/showhide] Q3.Consider the following statements/निम्नलिखित कथनों पर विचार करें :
  1. The Oceanic plates contain mainly the Silica and magnesium crust and are relatively thicker/महासागरीय प्लेट में  मुख्य रूप से सिलिका एवं मैग्नीशियम शामिल है एवं यह अपेक्षाकृत भारी है |
  2. The continental plates contain Silica and Aluminium crust and are relatively thinner/महाद्वीपीय प्लेटों में सिलिका तथा एल्युमिनियम शामिल है एवं यह अपेक्षाकृत हल्की है |  
  3. Radioactive decay and Residual heat are main sources of heat within the earth/रेडियोएक्टिव क्षय और अवशिष्ट ऊष्मा पृथ्वी के भीतर ऊष्मा के मुख्य स्त्रोत है

  • Only 1
  • Only 3  
  • 2 and 3
  • 1,2,3
[showhide type=”links3″ more_text=”Show Answer” less_text=”Hide Answer”] Ans. B is correct.
  • Statement 1 is not correct The Oceanic plates contain mainly the Silica and magnesium crust and are relatively thinner.
  • Statement 2 is not correct The continental plates contain Silica and Aluminium crust and are relatively thicker.

[/showhide] Q4. Consider the following statements/निम्नलिखित कथनों पर विचार करें
  1. If this rising limb is below the oceanic crust then it will result into Mid oceanic Ridge/यदि विस्तरण करता यह किनारा महासगरीय भूपर्पटी के नीचे होता है तो यह मध्य महासगरीय गर्त का रूप ले लेता है |
  2. If the rising limb is below the continental crust, then it will result into earthquakes/यदि  बढ़ता हुआ किनारा महाद्वीपीय भूपर्पटी से नीचे है तो परिणामस्वरूप भूकंप आएगा |
  3. On collision between two oceanic plates, the lengthier plate gets subducted as it is heavy/दो महासागरीय प्लेटों के बीच टकराव में ,अधिक लम्बाई वाली प्लेट टूट जाती है क्योंकि यह भारी होती है |
Which of the above statement/s is/are correct /इनमे से कौन सा कथन सही है?
  • Only 1
  • 2 and 3  
  • Only 2
  • 1,2,3
[showhide type=”links4″ more_text=”Show Answer” less_text=”Hide Answer”] Ans. D is correct.
  • Statement 1 is correct If this rising limb is below the oceanic crust then it will result into Mid oceanic Ridge.
  • Statement 2 is correct  If the rising limb is below the continental crust, then first the cracks will develop on the continental crust and will result into earthquakes.
  •  Statement 3 is correctAs both plates are oceanic plates, and are made of basalt, heaviness will be decided by length of oceanic plate. The lengthier the plate, the heavier it is.
[/showhide] Q5. Consider the following statements/निम्नलिखित कथनों पर विचार करें
  1. Andesitic moves upwards as it is lighter than surrounding mantle rock and oceanic crust./एंडेसाइट ऊपर की तरफ गति करते है क्यूंकि यह अपने चारों तरफ की मेंटल चट्टान तथा  महासागरीय भूपर्पटी से हल्की होती है
  2. Island in southeast asia are example of volcanic arc. /दक्षिण एशिया के द्वीप  चाप उदाहरण है
  3. Landform created from Ocean continental plate Collision is Oceanic volcanic arc./महासागरीय-महाद्वीपीय प्लेट के टकराव से निर्मित भूखंड को महासागरीय ज्वालामुखी चाप कहा जाता है |  
Which of the above statement/s is/are correct/इनमे से कौन सा कथन सही है ?
  • Only 1
  • 1 and 2  
  • Only 2
  • 1,2,3
