Match each geological dating method or paleontological principle on the left with its corresponding diagnostic scientific application on the right.
- Carbon-14 Radiometric DatingDetermining the absolute numerical age of relatively recent organic remains up to approximately 50,000 years old through isotope decay.
- Index Fossil BiostratigraphyCorrelating and establishing the relative age of geographically separated sedimentary strata using widespread, short-lived organisms.
- Law of Cross-Cutting RelationshipsDetermining that an igneous intrusion or fault is younger than the sedimentary rock layers it fractures or penetrates.
- PermineralizationPreserving internal cellular architecture when mineral-rich groundwater deposits silica or calcite into microscopic pore spaces.
Cevap
Carbon-14 Radiometric Dating pairs with calculating absolute numerical ages of recent organic materials via isotope decay; Index Fossil Biostratigraphy pairs with correlating relative ages of separated strata using widespread, short-lived organisms; Law of Cross-Cutting Relationships pairs with establishing that an intrusion or fault is younger than the strata it cuts; Permineralization pairs with preserving cellular detail by precipitating minerals into pore spaces.
Each geological and paleontological method is accurately paired with its definitive scientific mechanism: radiocarbon dating provides numerical ages for recent biological matter; index fossils calibrate strata across regions due to their narrow temporal and broad spatial occurrence; cross-cutting establishes that cutting structures are younger than host rocks; and permineralization preserves cellular structures via mineral saturation in voids.
