Question
Some sedimentary rock layers are damaged by an earthquake. The shaking of the ground caused a landslide.Identify which is younger.The sedimentary rock layersThey are the same ageThe earthquake
Solution
The earthquake is younger. This is based on the principle of superposition in the field of geology, which states that in undisturbed layers of rock, the oldest layers are at the bottom and the youngest are at the top. In this case, the sedimentary rock layers were already present when the earthquake occurred, causing a landslide. Therefore, the earthquake, and the changes it caused, must be younger than the sedimentary rock layers.

Which statement explaining the age of the rock layers best supports the answer to Part A? ARock layers that contain fossils are always the oldest rock layers and can be used to determine the ages of rock layers above them.BGeologic events like earthquakes can erase rock layers from the geologic timescale and make it difficult to know the ages of different rock layers.COlder rock layers will always be directly below younger rock layers unless they have been disturbed by geologic activity.DRock layers that are the thickest are the oldest because they represent a longer span of time in which the rock layer was formed
