Detailed Solution & Logic
physical weathering/ भौतिक अपक्षय
Explanation :
Exfoliation is a type of physical (mechanical) weathering in which the outer layers of rocks peel off in thin sheets, like the layers of an onion. This happens due to repeated heating and cooling, which causes the rock to expand and contract. Over time, the outer layers crack and separate from the rock surface without changing the rock's chemical composition.
व्याख्या:
Exfoliation (परतदार अपक्षय) भौतिक (यांत्रिक) अपक्षय का एक प्रकार है। इसमें चट्टानों की बाहरी परतें तापमान के बार-बार बढ़ने और घटने के कारण फैलती और सिकुड़ती हैं, जिससे वे प्याज़ की परतों की तरह धीरे-धीरे उखड़कर अलग हो जाती हैं। इस प्रक्रिया में चट्टान की रासायनिक संरचना में कोई परिवर्तन नहीं होता, इसलिए इसे भौतिक अपक्षय कहा जाता है।
