How does elastic deformation of rocks differ from brittle or plastic deformation?
A)It only occurs are very fast or high strain rates.
B)It is reversible or recoverable and when the stress is removed, the rocks snap back to their original shape or position.
C)It only happens to rocks that can bounce.
D)It can only occur once and never happens in cycles.

Elastic deformation is a temporary deformation that is reversible or recoverable, meaning that when the stress is removed, the rocks snap back to their original shape or position. This is different from brittle deformation, which is irreversible and leads to the formation of fractures, and plastic deformation, which is irreversible and leads to permanent deformation of the rock. Elastic deformation can occur at any strain rate and is not limited to a specific type of rock. It can also occur multiple times in cycles.
