The Geologic Cycle

• The vast give-and-take at the Earth-atmosphere-oce
  an interface or cycling within the lithosphere
• Fueled by the sun and Earths internal heat
• Hydrologic Cycle
• Rock Cycle
• Tectonic Cycle

11
The Geologic Cycle

• Rock Cycle
• Rock assemblage of minerals bound together or a
  mass of a single mineral  
• Minerals inorganic, nonliving, natural compound
  having a chemical formula and crystalline
  structure  
• Igneous Processes  
• Sedimentary Processes  
• Metamorphic Processes

Plate Tectonics  

• Conceptual model and theory of crustal movement  
• Continental drift
• Sea-floor spreading
• Subduction of the Crust
