A scientist studying chrons and subchrons is working with __________.
A) radiometric dating
B) fluorine analysis
C) the geomagnetic polarity time scale
D) obsidian hydration

Question

Quizplus · Accepted Answer

The geomagnetic polarity time scale is used to study chrons and subchrons, which are changes in the polarity (direction) of the Earth's magnetic field over time. This allows scientists to date rocks and other materials based on their magnetic properties. Radiometric dating (A) and obsidian hydration (D) are other dating methods but not specifically used for studying chrons and subchrons. Fluorine analysis (B) is a method used to determine the relative age of fossils, not rocks.
