Which of the following statements best describes the difference between absolute dating and relative dating of rocks?

Absolute dating provides a specific date or range of dates for an object, while relative dating determines the order of events without giving an exact time.

Relative dating is more accurate than absolute dating in determining the age of samples.

Relative dating uses chemicals to determine the age of fossils, while absolute dating uses the layers of rock.

Absolute dating can only be used on fossils or formerly living things, while relative dating is used on archaeological artifacts.
