Diagram 15 minutes The first page of the Interpreting Geologic History of NYS Diagram is extremely important, in that it very clearly delineates how to interpret the vast amount (and in some cases, too much) of information contained in the reference tables. The geologic time scale (GTS) is a system of chronological dating that relates geological strata (stratigraphy) to time. It is used by geologists, paleontologists, and other Earth scientists to describe the timing and relationships of events that have occurred during Earth's history. Geologic Timeline Analysis. Directions: Begin by filling in the blank boxes on the time scale diagram on the right, using the diagram on p. 138. Then, answer the following questions, referring to your timeline, green textbook (p. 136 – 141). 1) Look at the three major eras shaded on your timeline. gsa geologic

A geologic time scale is composed of standard stratigraphic divisions based on rock sequences and is calibrated in years (Harland and others, 1982). Over the years, the development of new dating methods and the refinement of previous methods have stimulated revisions to geologic time … Geological Visualization Tools and
Structural Geology Geologists use several visualization tools to understand rock outcrop Provided are a complete geologic map (the top of the diagram) and three of the four vertical cross sections (the south, east, and west sides of the block diagram).
