GEOL 1001 Lecture : Geology Notes
Document Summary
Scientific method - the scientific method involves making observations, formulating and testing a hypothesis. There is no fixed path that scientists follow that leads to knowledge. Uniformitarianism states that the physical, chemical, and biological laws that operate today have also operated in the geologic past. Densities the crust is low density rock, the mantle is high density rock, the outer core is highly dense liquid metal and the inner core is the most dense. Geologic time is vast and includes billions and millions of years. Continental drift theory that the continents were not always in the places they are now he wegner suggested that there was a single continent known as pangea. Evidence of this is that the continents fit together like jigsaw pieces, there is fossil evidence that match across the seas, and rock types and geologic features such as the andes mountains they match together.
