Question

Brittle deformation of rock bodies is characterized by slow internal flow of the rock material. True False

Answer 1

The answer is false. The brittle deformation means breaking of rocks into smaller pieces. This then leads to displacement of the Earth's crust as well as fracturing. It is favorable than ductile deformation.Hope this is the answer and would be of help.

Answer 2

False. Brittle deformation happens when there is a continuous force applied to a rock. As the force is gradually increased, little change occurs in the rock until suddenly it fractures.
The rocks that undergo brittle deformation tend to fracture into joints and faults.
