which of these faults, if any, were formed under compression?\na\nb\nc\na and b
Answer
Brief Explanations:
In geology, reverse faults are formed under compressional stress. Compression causes one block of rock to be pushed up over another. By observing the fault - types in the images, we identify the one with characteristics of a reverse fault which is formed under compression.
Answer:
(Without seeing the specific fault - type details in the images, we can't give a definite letter answer. But the general knowledge is that reverse faults are formed under compression. If one of the images shows a reverse fault, that would be the answer.)
