What type of deformation is shown in this photograph?

Question

Quizplus · Accepted Answer

The photograph shows a cross-section of a rock that has undergone deformation. However, there is no clear indication of displacement or rotation. The most likely explanation for the observed deformation is internal strain within the rock, which has caused it to fold and warp. Therefore, the best choice is C, internal strain of the rock. Columnar joints are a separate geologic feature unrelated to the deformation shown in the photograph.
