धरती के अंदर 'आग का गोला', बाहर आते ही मचाते हैं तबाही
पृथ्वी की टेक्टॉनिक प्लेटों के भीतर मौजूद ज्वालामुखी उस तरह नहीं फूटते जैसा वैज्ञानिकों ने सोचा था. एक नए अध्ययन से पता चला है कि इन ज्वालामुखियों के भीतर का मैग्मा पानी की जगह कार्बन डाइऑक्साइड द्वारा जमीन से ऊपर और बाहर जाता है.
मैग्मा पहले के अनुमान से कहीं अधिक गहराईस से निकलता है. पृथ्वी के आवरण में 18 से 27 किमी की गहराई पर उत्पन्न होता है, ना कि बाहरी परत में यानी 7 से 13 किमी की गहराई पर.
