Document Summary
Stratigraphy: the study of layers - of rocks. Creating the order of history derived from the layers of the rocks. Paradigm: a fundamental change in the basic concepts and experimental practices of a scienti c discipline. The earth"s surface is always moving (4cm to the west per year) - no part of the earth is stable. Sea oor sledding - progressive widening of the oceans. Pangea: was a supercontinent that existed, now they are spread apart. Supercontinent cycle: evolutionary history of aggregation and the dispersal of the continents outcrops - when you can actually see the shape of the rocks ex) tent rocks. Plate tectonics: building of plates and how to get rid of them plate refers to thin layers of rock (40-70cm thick) tectonics is to build stuff. Important course themes: how our planet works ( plate tectonics") from its deep interior to its surface, earth history: using plate tectonic theory to reconstruct past continents/oceans (the.
