Answer :
Final answer:
Geologists use relative and absolute dating methods to establish the geologic time scale with considerable accuracy.
Explanation:
Geologists use relative dating to determine the sequence of events without assigning specific ages. In contrast, absolute dating involves using radioactive isotopes to assign numerical ages to rocks or minerals. By combining these methods, scientists can establish the geologic time scale to organize Earth's 4.6 billion years of history with considerable accuracy.
