Document Summary
Index fossils organisms that evolved very quickly. We can be quite specific about the time range that they lived in. Isotope same number of protons, but different number of neutrons: james hutton pioneer geologist. The rock record is incomplete as a lot of sediments record distinct events separated by long periods where nothing happens: niagara escapement have strikes of hard rock layers which are difficult to erode. The dip is to the west and the strike is north/south: normal faults most common faults where rocks have been pulled apart. Ex: crust that has been pulled apart in iceland and the east african rift. We use information of faults to indicate where the rocks have been shoved together or pulled apart: paired normal faults where the pacific plate has been pushed down below the. And that gives us an idea of the absolute age: reverse faults where rocks have been extended. Can be found near mountain ranges such as the alps.
