16. which principle states that rock fragments in sedimentary layers must be older than the surrounding sediments?\na. principle of superposition\nb. principle of unconformity\nc. principle of inclusions\nd. principle of cross - cutting relationships
Answer
Brief Explanations:
The principle of inclusions states that rock - fragments (inclusions) within sedimentary layers must be older than the surrounding sediments. The principle of superposition deals with the relative ages of layers where lower layers are older. Unconformity is a gap in the geologic record. The principle of cross - cutting relationships pertains to the relative ages of intrusions and faults compared to the rocks they cut through.
Answer:
C. Principle of inclusions
