Answer
| Block Disintegration | Exfoliation |
|---|---|
| The sudden rise and fall of temperature causes expansion and contraction of rocks. The repeated action leads to tension and splitting of rocks known as block disintegration. | Sudden temperature changes may cause fissures into which water penetrates which in turn stimulates chemical weathering. Most rocks are not good conductors of heat. The sudden contraction and expansion peels off the outer layer known as exfoliation. |
