Answer 1

Answer: (A), (D)

The correct options are
A It leads to the destruction of property.
D It is dangerous for human lives.

Sudden or rapid mass movements are dangerous and destructive. They cause loss of property and sometimes human lives too. Humans have been continuously trying to find ways to prevent their occurrence or at least, reduce the impact. Oxidation is a chemical weathering process, while the peeling away of rock surface is a physical weathering process called exfoliation.
