improvements in dating of rocks and fossils-49

In addition, the oldest known moon rocks are 4.5 billion years old.

Since the moon and the Earth probably formed at the same time, this supports the current idea of the Earth's age.

The most common rocks observed in this form are sedimentary rocks (derived from what were formerly sediments), and extrusive igneous rocks (e.g., lavas, volcanic ash, and other formerly molten rocks extruded onto the Earth's surface).

The layers of rock are known as "strata", and the study of their succession is known as "stratigraphy".

Other techniques include analyzing amino acids and measuring changes in an object's magnetic field.

Scientists have also made improvements to the standard radiometric measurements.

These layers are like bookends -- they give a beginning and an end to the period of time when the sedimentary rock formed.

By using radiometric dating to determine the age of igneous brackets, researchers can accurately determine the age of the sedimentary layers between them.

It is these highly consistent and reliable samples, rather than the tricky ones, that have to be falsified for "young Earth" theories to have any scientific plausibility, not to mention the need to falsify huge amounts of evidence from other techniques.

This document is partly based on a prior posting composed in reply to Ted Holden.

The most widely known form of radiometric dating is carbon-14 dating.
