Consider the following statements about Mechanical Weathering:<br>1. More compact and highly consolidated rocks are least affected by freeze-thaw weathering.<br>2. Shattering of rocks is more common in hot deserts.<br>3. Crystalline rocks are often prone to exfoliation.<br>Which of the statements given above is/are <strong>CORRECT</strong>?
- A. 1 and 2 only
- B. 1 only
- C. 2 and 3 only
- D. 1, 2 and 3 ✓
Correct Answer: D. 1, 2 and 3
Explanation
All statements are correct. Dense rocks lack pores for water to freeze in; extreme diurnal temperature changes in hot deserts cause thermal expansion/contraction leading to shattering; and unloading/thermal stress causes exfoliation in crystalline rocks like granite.
