Geology (from the Ancient Greek γῆ, gē ("earth") and -λoγία, -logia, ("study of", "discourse")) is an earth science concerned with the solid Earth, the rocks of which it is composed, and the processes by which they change over time. Geology can also include the study of the solid features of any terrestrial planet or natural satellite such as Mars or the Moon.

Carbon-14, the isotope that archeologists use in radioactive dating, is cosmogenic—continuously created. Marcia Bjornerud is a professor of geology at Lawrence University, in Appleton, Wisconsin,

Tristan da Cunha. argon dating gives us a way to use volcanic rock from the island as a very slow clock which can tell us how long ago eruptions occurred. By examining rock samples in a mass.

Sep 20, 2007  · The use of carbon-14 dating is often misunderstood. Carbon-14 is mostly used to date once-living things (organic material). It cannot be used directly to date rocks; however, it can potentially be used to put time constraints on some inorganic material.

The Origin of Earth’s Radioactivity SUMMARY: As the flood began, stresses in the massive fluttering crust generated huge voltages via the piezoelectric effect. 4 For weeks, powerful electrical surges within Earth’s crust—much like bolts of lightning—produced equally powerful magnetic forces that squeezed (according to Faraday’s Law) atomic nuclei together into highly unstable.
