Answer

  • In the cold regions, the temperature drops below 0°C for a period of time.
  • The water that has percolated through the cracks in the rocks freezes and turns into ice.
  • Ice requires greater space than water. Tension is developed when the ice tries to acquire greater space.
  • The continuous process of freezing and melting finally leads to the breaking of the rock mass.
