Exploring The Geologic Column And Its Key Concepts

The video tutorial explains the geologic column, a chart representing rock layers worldwide. It breaks down the meanings of related terms using prefixes and suffixes, such as 'geo' for earth and 'ology' for study. The geologic column consists of strata, with each layer called a stratum. The Phanerozoic Eonothem, a major interval, is divided into Paleozoic, Mesozoic, and Cenozoic erythems, which are further divided into systems like Cambrian and Jurassic. Understanding these terms aids in learning about the geologic column.
