What determines whether a rock deforms in a brittle fashion versus a ductile fashion?
A)temperature
B)rock type
C)rate of deformation
D)all of the above

Question

Quizplus · Accepted Answer

The way a rock deforms, whether in a brittle or ductile manner, is influenced by a combination of factors including the temperature at which the deformation occurs, the type of rock, and the rate at which the deformation happens. High temperatures and slow deformation rates tend to favor ductile deformation, while low temperatures and rapid deformation rates favor brittle deformation. Different rock types also have varying propensities for either brittle or ductile behavior based on their composition and structure.
