7. GLY 2030C Philosophy and Fundamental Concepts Environmental geology: Applied geology Uses geologic information to assess: Natural hazards (floods, quakes, slides, etc.) Landscape/ environmental impact statement Earth materials Hydrologic processes Geologic processes Environment: the total set of circumstances surrounding an individual or community Physical Atmosphere (air), Hydrosphere (water), Geosphere (landforms) Social and cultural conditions Ethics, Economics, Aesthetics

8. GLY 2030C8 How Geologists Work: The Scientific Method Observation Hypothesis Collect data, organize, and analyze Multiple hypotheses developed to explain the data Hypothesis testing and interpretation of results Theory evolves as tests are successful Law or Theorem Philosophy and Fundamental Concepts

9. Philosophy and Fundamental Concepts Cultural Basis for Environmental Awareness Origin of our present condition lies in the past Functional categories of society significant in environmental studies For solutions - may have to look to the future Overpopulation, hazardous waste, global warming, resource depletion Industrial revolution changed human/envt. relationship: Increased population increased demand on resources and increased toxic waste Global Environmental Concerns: Developing nations are pressured to exploit resources
