- The gradual distinctigration of rocks is caused by atmosphere forces.
- The rocks in exposed to heat expand and contract when cooled down.
- As surface rock contract 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.
- It easier to chip small pieces of rock from the outside layer rather than from the core of the rock.
- Thus we can say the rocks are harder inside and outside.
