What is the primary composition of Earth's outer core?
Correct Answerसही उत्तर
B. Iron and NickelB. लोहा और निकेल
Explanationव्याख्या
Earth's core is primarily composed of Iron (Fe) and Nickel (Ni), often called the NIFE layer.
While the inner core is solid due to immense pressure, the outer core is a fluid layer approximately 2,260 km thick, remaining liquid because the temperature is high enough to overcome the pressure.
पृथ्वी का कोर मुख्य रूप से लोहे (Iron) और निकेल (Nickel) से बना है, जिसे अक्सर 'NIFE' परत भी कहा जाता है। अत्यधिक दबाव के कारण आंतरिक कोर ठोस है, जबकि बाहरी कोर लगभग 2,260 किमी मोटी एक तरल परत है। तापमान बहुत अधिक होने के कारण यह हिस्सा तरल अवस्था में ही रहता है।
