GEOLOGY is a System of CLASSIFICATIONS, a Language (excellent bookkeeping, without Accounting). Earth Science uses their Nomenclature, with Mathematics and PHYSICS, to understand the Earth. Learning a Language yields NO INSIGHT into the DYNAMICS of the Earth, when TERMS are used for FACTS! I will Correct inaccurate Assertions, as I find them. Ignore ASSERTIONS such as Mantle Plumes and Plate Theory- which are ARTIFICIAL concepts, created by Man; these require Continuous ADJUSTMENT!
