GEOL 1001 Chapter : Geology Notes Chapters 1-4
Document Summary
In 1872 congress designated yellow stone as the country"s first national park. Chapter two happen: pre 1788 natural sciences only consisted of physics, chemistry, astronomy, and biology, geology as a natural science, in 1788 james hutton wrote theory of earth textbook. Geology looks at interrelationships: science requires, critical thinking, testing with experiments, data are explained, build on past observations, modify hypothesis. In 1543 copernicus suggested that earth rotates around the sun (heliocentric theory) Church said no because theory was not tested. In early 1600s galileo used telescope and showed that copernicus was right. Continental drift: plate tectonics-an example of geology, motion of continents, bullard showed reconstruction of continents on the computer in 1955, plate tectonics were initially based on earthquake disruption, earthquakes occurring in certain places (at plate boundaries) Earth"s history and geological time: earth"s age=4. 56 billion years, dating methods, relative ages-estimates based on observations with no real known time or age, time-rock units, chronostratigraphic names, rocks correlated to ages.
