impact on humans and we in return have an impact of geologic processes We will learn the basics of how earth works Materials composing the earthProcesses operation beneath and upon the earth s surface Geology is the science that pursues an understanding of the planet earth Geology is complex and uncles many areas of specialization For success in this course 1 Read the chapter before coming to class

started to gravitationally collapse 2 The nebula contracted into a rotating disk that was heated by the conversion of gravitational energy into thermal energy 3 Cooling of the nebular cloud caused rocks and metallic material to condense into tiny particles 4 Repeated collisions caused the dust size particles to gradually coalesce into asteroid size bodies that accreted into planets within a few million years Scientific methods cid 127 Observations Hypotheses Data acquisition Analyses Rinse and repeat Dissemination A THEORY is not the same as a HYPOTHESIS Earth System Spheres Hydrosphere

boundaries that change the face of planet Earth Grand unifying theory in Geology Continental Drift 1st proposed in 1951 by German meteorologist Alfred Wegener A supercontinent consisting of all of Earth s landmasses called Pangaea once existed Pangaea subsequently broke apart Continents are mobile Evidence used in support of continental drift The continental jigsaw puzzle continental shelf fit Rock types and geologic features mountain ranges Ancient climates coal swamps cid 127 Glacial evidence broken apart glaciers Fossil evidence identical fossil organisms are found on continents now separated by vast oceans The great debate There was strong opposition to this hypothesis from all areas of the scientific community cid 127 Wegener incorrectly suggested that the gravitational forces of the moon and sun were capable of moving the continents cid 127 Wegener incorrectly suggested that continents broke through the Ocean crust Theory of
