Overview

Explore the fascinating world of geologic time in this comprehensive 55-minute lecture. Delve into key concepts such as numerical dates, principles of superposition, original horizontality, lateral continuity, crosscutting, and occlusions. Examine the importance of conformity, disconformity, and fossils in understanding Earth's history. Investigate the fossil record, correlation techniques, and fossil assemblages. Learn about isotopes, radioactivity, and their role in dating geological events. Gain insights from resources like the USGS Fossils, Rocks and Time publication, Maryland Geological Survey's fossil information, and PBS Eons' Brief History of Geologic Time video. By the end of this lecture, acquire a solid foundation in geologic time scales and their significance in Earth sciences.
