This introductory physical science course investigates the composition of the earth and the geologic processes by which it formed. Emphasis is placed on the earth?s unifying theory plate tectonics and the associated activities of volcanism, earthquakes, and mountain building. Topics will include crystals, minerals and rocks, their distribution within the planet, and the evolution of the earth across deep time. The sculpturing of the surface of the planet by wind, waves, streams, glaciers, and landslides will also be considered. (C-ID GEOL 100) (CSU/UC) (AA/AS-B2, CSU-B1, IGETC-5A)
