Why do you think the rock is harder inside than outside? – InterviewSolution

1.	Why do you think the rock is harder inside than outside?
Answer» The gradual disintegration of rocks is caused by atmosphere forces. The rocks when exposed to heat expand and contract when cooled down. As surface rock contracts and expands and contracts again, it gradually becomes brittle and begins to break down. Water reacts with the chemicals in the rock and further weakens it. These processes by which the rocks are weakened and broken are called ‘weathering’. It is easier to chip small pieces of rock from the outer layer rather than from the core of the rock. Thus we can say the rocks are harder inside than outside.
