Why do corners and edges of rocks weather faster in spheroidal weathering?
Explanation opens after your attempt
A. क्योंकि वे अधिक सतह क्षेत्र के कारण अधिक खुले रहते हैंBecause they are more exposed due to greater surface area
Concept
Corners and edges are exposed to weathering from several directions. Therefore the rock may gradually become rounded.
Why this answer is correct
The correct answer is A. क्योंकि वे अधिक सतह क्षेत्र के कारण अधिक खुले रहते हैं / Because they are more exposed due to greater surface area. Corners and edges are exposed to weathering from several directions. Therefore the rock may gradually become rounded.
Exam Tip
कोने और किनारे कई दिशाओं से अपक्षय के संपर्क में रहते हैं। इसलिए चट्टान धीरे धीरे गोल आकार ले सकती है।
