Label the year and name of each geologic era on your geologic time scale. Using the 1cm = 10 million years, measure the distance to each era from Today by using the following information.
Figure 4.3 Geological Time Scale . PRINCIPLES OF STRATIGRAPHY. These principles for relative dating of rock strata were first developed by Danish geological pioneer Nicholas Steno in Dissertationis prodromus (1669) and later formulated by James Hutton in Theory of the Earth (1795) and embellished upon by Charles Lyell in Principles of Geology ...
The goals of this chapter are to: Illustrate the immense scale of geologic time. Summarize the geologic time scale. Explain the principles of relative dating and unconformities. Apply principles of relative and absolute dating to determine the ages of rocks. 1.1 Introduction. Earth is 4.543 billion years old.
Interactive Geological Timescale. This visualisation of the International Commission on Stratigraphy's Chronostratigraphic Chart uses the SKOS & Time Ontology in OWL representation of it as the Geological Timescale (2020) for its data. The work to develop this was supported by CSIRO's Environmental Informatics Group and the Geological survey of ...
geologists have created a geologic time scale to make their job of studying Earth’s history easier. The geologic time scale is a standard method used to divide the Earth’s long history into smaller parts.
The lithosphere can be visualized as a collections of plates, kind of like puzzle pieces, that interact in tectonic processes. The lithospheric plates ride on the viscous asthenosphere, or lower mantle. The convection currents in the asthenosphere drive the process of plate tectonics.
1. Analyze the geologic time scale. 2. Explain the creation of the geologic time scale. 3. Understand the difference between geologic time and human time scales. 4. Compare and contrast relative and absolute dating. Time Required: 75 minutes. Materials Needed: Teacher computer with internet access. Projector/Smartboard.
