Question

which technique would be the best way for a geologist to get a sense of the history of an area? looking for and examining the oldest rocks in the area examining the relationships and patterns in rock layers surveying the overall shape of the landscape observing current geological features and characteristics

Explanation:

Geologists study rock layers (strata) to understand geological history. The principle of superposition (younger rocks on top of older ones) and other relationships (like cross - cutting) in rock layers provide a chronological record. Just looking at the oldest rocks misses the sequence. Surveying landscape shape or current features gives limited historical context compared to rock - layer analysis.

Answer:

examining the relationships and patterns in rock layers
