The diagram above shows several rock layers and other geologic features. Each feature is labeled with a unique letter. The order of the letters do not necessarily reflect the order in which the features formed. Examine the diagram, and answer the question that follows. Using the principles of original horizontality, superposition, and cross-cutting relationships, determine which of the following features is the youngest.

Answer 1

Based on the principles of original horizontality, superposition, and cross-cutting relationships, it can be determined that feature G is the youngest. This is because feature G cuts across both the rock layers and the fault line (feature H), indicating that it is the most recent geologic event to occur.
