Q. The "Caldera" of a volcano refers to:

ज्वालामुखी का "काल्डेरा" संदर्भित करता है:

A

B
The central vent
केंद्रीय वेंट
C
The main crater

D

Explanation

A caldera is a large, basin-like depression that forms when a volcano’s magma chamber empties during an eruption, causing the ground above to collapse. Calderas can be many kilometers wide and may later fill with water, forming crater lakes.

काल्डेरा एक विशाल, बेसिन जैसा गड्ढा होता है जो ज्वालामुखी विस्फोट के दौरान उसके मैग्मा कक्ष के खाली होने और ऊपर की ज़मीन के ढहने से बनता है। काल्डेरा कई किलोमीटर चौड़ा हो सकता है और बाद में पानी से भरकर क्रेटर झीलें बना सकता है।
