Respuesta :
Answer: c) ice fracturing a stone
Explanation: because physical weather does not change the state of the object it more so breaks it down
The best example of physical weathering is ice fracturing a stone.
Answer: Option C
Explanation:
Physical weathering is the phenomenon of breaking a rock due to temperature, pressure or heat without affecting its chemical composition. This process is a geological effect acting on all kinds of rocks. The breaking of rocks means creation of fracture, cracks or complete breaking of rocks but the composition of minerals in the rock will attain constant.
It occurs generally at high temperature or at very low temperature or high pressure. Among the given options, physical weathering can be explained by ice fracturing a stone.
So in this case, the low temperature leads to formation of ice on the surface of the rocks or stones which will absorb water leading to fracture on the stone surface which will be increasing with further lowering of temperature thus permanently breaking the stone with same composition.
