Chronological arrangement of stratified rocks
WebA geologist examines a layer of sedimentary rock strata that contains pebbles of granite. From this, the geologist could infer that: a. An older layer of granite is below the sedimentary rock b. An older layer of granite is above the sedimentary rock c. A younger layer of granite is below the sedimentary rock d. WebOct 2, 2024 · Absolute dating, methods that produce specific chronological dates for objects and occupations, was not available to archaeology until well into the 20th century. Stratigraphy and the Law of Superposition Stratigraphy is the oldest of the relative dating methods that archaeologists use to date things.
