Question

Base your answer on the three bedrock outcrops below and on your knowledge of Earth science. The outcrops, labeled I, II, and III, are located within 15 kilometers of each other. Lines AB and CD represent unconformities. Line XY represents a fault. No overturning of the layers has occurred. The unconformities at AB and CD resulted from A) uplift and erosion, followed by subsidence and deposition B) movement along a crack between two rock layers C) contact metamorphism between two sedimentary layers D) regional metamorphism of deeply buried sedimentary rocks

Answer 1

A) uplift and erosion, followed by subsidence and deposition

Step-by-step explanation:

• As the Unconformity refers to the buried erosional and non-depositional surface that spates the rocks masses and this indicates the sediments depositions does not continues

• The older are exposed to erosion for some interval before the setting of the younger layers. There can be disconformity, nonconformity ad para disconformity.
