A geologist found two sets of sedimentary rock layers separated by an irregular surface. He also observed that the rock layers underlying this surface are extremely folded.Based on the case scenario, what is the most likely rock contact that the geologist can conclude from his/her observations?

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

“A geologist found two sets of sedimentary rock layers separated by an irregular surface. He also observed that the rock layers underlying this surface are extremely folded."Based on the case scenario, what is the most likely rock contact that the geologist can conclude from his/her observations?

A	Angular unconformity
B	Disconformity
C	Conformable contact
D	Intrusive contact

Explanation:

Detailed explanation-1: -An unconformity is a buried erosional or non-depositional surface that separates two different-age rock masses or strata, indicating that the deposition of sediments was not continuous.

Detailed explanation-2: -An unconformity is a buried erosional or non-depositional surface separating two rock masses or strata of different ages, indicating that sediment deposition was not continuous.

Detailed explanation-3: -An unconformity is a buried erosional or non-depositional surface separating two rock layers or strata of different ages, indicating that sediment deposition was not continuous.

Detailed explanation-4: -The Law of Original Horizontality suggests that all rock layers are originally laid down (deposited) horizontally and can later be deformed. This allows us to infer that something must have happened to the rocks to make them tilted.
