GEOL 1001 : Geology Final
Document Summary
Ii: geology is the study of earth. How do geologists study earth: scientific method. How do we study earth as a system of interacting components: study subsystems- climate (atmosphere, hydrosphere, cryosphere, biosphere, and lithosphere) and plate tectonics systems. 65 million years ago: 200,000 years ago our species, homo sapiens, appeared. Terms: asthenosphere, climate, climate system, convection, earth system, fossil, geodesy, geodynamo, geologic record, geology, geosystem, inner core, lithosphere, magnetic field, mantle, outer core, plate tectonic system, principle of uniformitarianism, scientific method, seismic wave, topography. Terms: continental drift, convergent boundary, divergent boundary, geodesy, island arc, isochron, magnetic anomaly, magnetic time scale, mantle plume, mid-ocean ridge, pangea, plate tectonics, relative plate velocity, rodina, seafloor spreading, spreading center, subduction, transform fault. How do atoms combine to form the crystal structures of minerals: chemical elements react to form compounds by gaining or losing (ion) or sharing electrons.
