Question

Which relative dating principle states that a rock mass adjacent to one containing fragments is older than the rock containing the fragments?
A. Principle of cross-cutting relationships B. Principle of original horizontality C. Principle of inclusions D. Principle of superposition

Answer 1

The correct answer is **C. Principle of inclusions**. This principle states that any rock fragments (inclusions) within a rock mass must be older than the rock that contains them. Thus, the rock mass with inclusions is considered younger than the fragments it incorporates.
