उत्तर
Temperature is the main factor behind granular weathering because -
- In hot desert areas, the diurnal range of temperature is high.
- As the temperature increases with the rising sun, the rock gets heated and cools down with the decrease in temperature.
- The minerals in the rock react differently to the temperature increase due to continuous heating and cooling.
- Consequently, it leads to the development of stress within the rock and molecular or granular disintegration takes place.
