Question & Answer (English)

Exfoliation is a form of ________.

  1. chemical weathering
  2. biochemical weathering
  3. physical weathering — Correct Answer
  4. mass wasting
Explanation:

Exfoliation involves the peeling off of curved sheets or shells from rocks, similar to peeling an onion. This happens due to the expansion of rock caused by temperature changes or the release of pressure (unloading). Since this process involves the mechanical breakdown of rock without altering its chemical composition, it is a form of physical weathering.

प्रश्न एवं उत्तर (हिंदी)

अपपर्णन (Exfoliation) ________ का एक रूप है।

  1. रासायनिक अपक्षय (chemical weathering)
  2. जैव रासायनिक अपक्षय (biochemical weathering)
  3. भौतिक अपक्षय (physical weathering) — सही उत्तर

स्पष्टीकरण:

अपपर्णन (Exfoliation) एक ऐसी प्रक्रिया है जिसमें चट्टानों की ऊपरी परतें प्याज के छिलके की तरह उतरने लगती हैं। यह मुख्य रूप से तापमान में बदलाव या दबाव कम होने (unloading) के कारण चट्टानों के फैलने से होता है। चूंकि इस प्रक्रिया में चट्टान रासायनिक रूप से नहीं बदलती बल्कि केवल टूटती है, इसलिए इसे भौतिक अपक्षय (Physical Weathering) का एक रूप माना जाता है।
