Stratigraphy[r]: The interdisciplinary science field that describes all rock bodies that form the Earth's crust and the manner in which they are organised into distinctive units that are then mapped. [e]
Fossil[r]: A naturally preserved record of ancient life. [e]
Age (geology)[r]: The fundamental chronostratigraphic unit. [e]
Geologic time scale[r]: Measurement of the geologic history of the earth which can be broadly classified into two periods: the Precambrian supereon and the Phanerozoic eon. [e]
Geochronology[r]: Science of determining the absolute age of rocks, fossils, and sediments, within a certain degree of uncertainty inherent within the method used. [e]
Hydrology[r]: The interdisciplinary study of the movement, characteristics and distribution of water, surface-water (fresh water and salt water), groundwater, and water-quality. [e]
Palynology[r]: The science of the study of contemporary and fossil palynomorphs as well as associated particulate organic matter (POM) in sedimentary strata. [e]
Lithostratigraphy[r]: Stratigraphy based on the interpretation of physical and petrographic properties of rocks. [e]
