Q1. Which sequence correctly arranges these theories of crustal movement in the order they were proposed?
भूक्रस्ट की गति के इन सिद्धांतों को उनके प्रस्तावित किए जाने के क्रम में सही ढंग से व्यवस्थित करने वाला क्रम कौन सा है?
- A. Continental drift → convectional current theory → sea-floor spreading → plate tectonics / महाद्वीपीय विस्थापन → संवहनीय धारा सिद्धांत → सागर-तल विस्तार → प्लेट विवर्तनिकी
- B. Sea-floor spreading → continental drift → plate tectonics → convectional current theory / सागर-तल विस्तार → महाद्वीपीय विस्थापन → प्लेट विवर्तनिकी → संवहनीय धारा सिद्धांत
- C. Plate tectonics → sea-floor spreading → convectional current theory → continental drift / प्लेट विवर्तनिकी → सागर-तल विस्तार → संवहनीय धारा सिद्धांत → महाद्वीपीय विस्थापन
- D. Convectional current theory → continental drift → plate tectonics → sea-floor spreading / संवहनीय धारा सिद्धांत → महाद्वीपीय विस्थापन → प्लेट विवर्तनिकी → सागर-तल विस्तार
Solution
Continental drift was proposed in 1912, followed by the convectional current theory in the 1930s, sea-floor spreading in 1961, and plate tectonics in 1967.
महाद्वीपीय विस्थापन 1912 में प्रस्तावित किया गया, इसके बाद 1930 के दशक में संवहनीय धारा सिद्धांत, 1961 में सागर-तल विस्तार, और 1967 में प्लेट विवर्तनिकी सिद्धांत प्रस्तावित किया गया।
Q2. Plates along the Arctic ridge move at less than $2.5$ cm per year, while plates along the East Pacific Rise move at more than $15$ cm per year. What does this difference mainly show?
आर्कटिक कटक के साथ प्लेटें प्रति वर्ष $2.5$ सेमी से कम गति से गतिमान होती हैं, जबकि पूर्वी प्रशांत उभार के साथ प्लेटें प्रति वर्ष $15$ सेमी से अधिक गति से गतिमान होती हैं। यह अंतर मुख्यतः क्या दर्शाता है?
- A. Plate movement rate depends only on how old the ocean floor is / प्लेट गति की दर केवल महासागरीय तल की आयु पर निर्भर करती है
- B. The Arctic ridge is a convergent boundary while the East Pacific Rise is a divergent boundary / आर्कटिक कटक एक अभिसारी सीमा है जबकि पूर्वी प्रशांत उभार एक अपसारी सीमा है
- C. The rate of plate movement is not the same everywhere on earth / प्लेट गति की दर पृथ्वी पर सभी जगह एक समान नहीं है
- D. All oceanic ridges spread at exactly the same rate / सभी महासागरीय कटक ठीक उसी दर से फैलते हैं
Solution
The large difference in speed between the two ridges shows that plates do not move at a uniform rate everywhere on earth.
दोनों कटकों की गति के बड़े अंतर से यह दर्शाता है कि प्लेटें पृथ्वी पर सभी जगह एक समान दर से गतिमान नहीं होती हैं।
Q3. At the San Andreas Fault, two plates slide past one another horizontally without any new crust being created or old crust being destroyed. Which type of plate boundary does this represent?
सैन एंड्रियास भ्रंश (फॉल्ट) पर, दो प्लेटें बिना किसी नई भूक्रस्ट के निर्माण या पुरानी भूक्रस्ट के विनाश के एक-दूसरे के सापेक्ष क्षैतिज रूप से सरकती हैं। यह किस प्रकार की प्लेट सीमा का प्रतिनिधित्व करता है?
- A. Transform or conservative boundary / रूपांतरण या संरक्षी सीमा
- B. Convergent or destructive boundary / अभिसारी या विनाशी सीमा
- C. Subduction boundary / अवतलन सीमा
- D. Divergent or constructive boundary / अपसारी या रचनात्मक सीमा
Solution
Where plates slide past each other without creating or destroying crust, the boundary is called transform or conservative, as at the San Andreas Fault.
जहाँ प्लेटें बिना भूक्रस्ट के निर्माण या विनाश के एक-दूसरे के सापेक्ष सरकती हैं, वहाँ सीमा को रूपांतरण या संरक्षी सीमा कहा जाता है, जैसा कि सैन एंड्रियास भ्रंश पर होता है।
