Question

if rocks can bend and stretch, but go back to their original shape, it is called 2 points
elastic deformity
plastic deformity
tectonic deformity
twisting deformity

if rocks bend and stretch too far, and are permanently deformed, it is called 2 points
elastic deformity
plastic deformity
tectonic deformity
twisting deformity

Explanation:

Elastic Deformity refers to the ability of a material (here, rocks) to deform (bend, stretch) and return to its original shape. Plastic Deformity means the material is permanently deformed after exceeding a certain limit. Tectonic Deformity is related to large - scale geological forces (not specifically about return to shape or permanent deformation as per the definitions here). Twisting Deformity is about rotational deformation, not the key aspects of return to shape or permanent deformation.

Answer:

First question: Elastic Deformity
Second question: Plastic Deformity
