Chapter 1: Introduction to Physical Geology and the Environment Geology: means the the study of the earth. Came into being in the late eighteenth century. Geologists are those who investigated planet earth and ways of exploiting the growing demand for minerals. William Smith published first detailed geological map in 1815. He was called the father of English geology. In North America geological mapping began in the mid-nineteenth century-driven by the need to locate resources for the expanding population. William Logan was the first to systematically describe the geology of Canada. Use to believe that the earth was 6000 years old, but the earth is actually 4500 billion years old. And within that time there have been dramatic changes in the physical geography of the planet. The German meteorologist Alfred Wegner, who wrote in 1912 of continental drift, suggested movement of continents in the twentieth century. o Continents use to be apart of a large land mass called the Pangaea but were moved apart. o He could evidence to support his idea but couldnt explain so he theory was not accepted. o Gathering of geological data demonstrated to geoscientists that continents do move and led to the plate tectonics theory. o J. Tuzo Wilson in the early 1970s was responsible for bringing together elements of what we call the plate tectonics theory. Geology involves greater amounts of time called deep time. www.notesolution.com
