Faulting and earthquakes are examples of ________ and generally occur when rocks are relatively ________. A. brittle deformation; cold B. ductile deformation; cold C. brittle deformation; hot D. ductile deformation; hot

Respuesta :

Answer: A. brittle deformation; cold.

Explanation: The Earth's crust is more brittle towards the surface as a result of cooling. Temperature changes can lead to rock expansion and contraction this continuous expansion and contraction will subsequently lead to fracturing or brittle deformation.

The outcome of brittle deformation in rocks is synonymous to that of broken plates i.e. fractures.

Examples of Brittle deformation could include Faulting and earthquakes, this process do occur as a result of rock been relatively cold.

  • Brittle deformation can be regarded as the shape change of a material which occur as a result of break in its chemical bonds.

  • Example of this is seen in Faulting and earthquakes. In natural rocks, brittle deformation is seen as a fracture.

Therefore option A is correct.
