Answer:
D. physical weathering
Explanation:
The geological process that initiates and leads to the breaking of the rocks is termed as the physical weathering. In this process, the chemical composition of the rocks do not undergo any change. The process of breaking of the rocks is both gradual and sudden. The movement of the earth, the change in the temperature, the rise and fall of the water level, the presence of ice rocks for longer duration of the time, and the melting of the snow are some of the reasons which causes the physical weathering.
The phenomena in the given expert represents the physical weathering.
