World of Geology Geology is all around us. 1. Geological Resources 2. “The Environment” 3. Geological Hazards 4. Planetary Geology 5. Engineering 6. Landforms and Surface Processes 7. Artistic Inspiration Geology forms the basis of our great civilizations Environmental Geology
The Cradle of Civilization Sprung from geology of the region Tigris River, Iraq
World of Geology –The Cradle of Civilization (Fertile Crescent) –Development limited by availability, e.g., soil, water, energy –Conflicts based on resources, e.g., water, minerals, oil, energy… Geological Resources
Geologic Resources Mineral Resources: metals, fertilizers, minerals, petroleum, construction
Geologic Resources Mineral Resources: metals, fertilizers, minerals, petroleum, construction Water resources: Lakes, Rivers, Springs, Groundwater
Geologic Resources Mineral Resources: e.g., Metals, fertilizers, minerals, petroleum, construction Water resources: e.g., Lakes, Rivers, Springs, Groundwater Energy: e.g., Oil, natural gas, coal, nuclear, silicon, hydroelectric (dams), hydrothermal (Earth’s heat)
The Geologist’s Job –Locating and Characterizing quantity and quality of geologic resources –Extracting geologic resources efficiently –Assessing environmental effects of extraction and use Geologic Resources
E.g., Misuse of Resources
Misuse of Resources Desiccation of the Aral Sea, Kazakhstan See Page Aral Sea Over Time
Overuse of Geologic Resources 1.7 billion are joining the “consumer class” and the environment can’t sustain this standard of living. (Worldwatch Institute, 2004) Emissions of Greenhouse gasses are accelerating global warming. (IGPCC, 2007) Climate change is accelerating melting of glaciers and driving mass extinctions (The Centre of Biodiversity and Conservation, Leeds University, UK) (Geology in the News)

Geology in Engineering Slope Failure Risk Assessment and Control To prevent slope failure engineers must understand the geology that forms and controls the slope
Geology in Engineering
Committee member John Burland, an engineer, promoted soil extraction as the best way to save the tower. In Pisa the tilted one is back in business after an 11-year effort to keep it from collapsing The Leaning Tower Straightens Up Engineers use knowledge of geology to design, protect and correct structures
Steve Squyres says that, even though the MER's work will have just begun, he'll feel like celebrating the moment he's got "six wheels in the dirt." Guided by MER specialists back on Earth, each rover will travel dozens of yards a day while investigating sites of interest. Geologists lead the mission “Robot geologist” explores Mars Planetary Geology
