Document Summary
Watt: invented the steam engine, started the industrial revolution. (where geology began) Logan: invented coal, in eastern canada, joggins. Stratigraphy: studies earth history as revealed by strata. Preserve rocks: need areas of rocks that are subducting (ocean basins, zones, basins: so, it floods with water and accumulate sediments: accommodation. Rock record: need area to have subsided in the past to accommodate these layers: grand canyon- have different layers of rock, conformable succession. When the layers sit on each other without any major breaks. Continuous record of environment, and accumulated information about the earth"s surface: unconformable succession: more common. More gaps than rock record: formal succession: index fossils. Fossils are lithified remains of an organism, and record evolution over time. We use the information from faults to indicate if the rocks were shoved or extended. When you get 2 normal faults: graben, which form these narrow rift valleus: reverse faults.
