If Earth had remained solid and had never become sufficiently molten, which process would have been hindered?यदि पृथ्वी ठोस ही बनी रहती और पर्याप्त रूप से कभी पिघली न होती, तो कौन-सी प्रक्रिया बाधित होती?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Effective separation of heavier and lighter materialsभारी और हल्के पदार्थों का प्रभावी अलगाव
The correct answer is C. When early Earth was sufficiently molten, its materials could move: denser substances tended to sink while less dense substances rose. If Earth had remained solid, this large-scale separation, or differentiation, would have been hindered.सही उत्तर C है। प्रारंभिक पृथ्वी के पर्याप्त रूप से पिघले होने पर उसके पदार्थ गतिशील हो सके: अधिक घने पदार्थ नीचे गए और कम घने पदार्थ ऊपर उठे। यदि पृथ्वी ठोस ही रहती, तो यह बड़े पैमाने पर अलगाव, यानी विभेदन, बाधित होता।
