  1. Chapter 4: Physical Measurements “Collecting data by recording physical properties of phenomena at or near the earth surface.”

  2. Where Do Physical Measurements Come From? 1. You can take measurements directly in the field 2. You can take samplesphysical materials from the field and measure them in the lab. 3. Recreate a test environment by using a physical model.

  3. Geodetic Measurement • What is the size and shape of the earth? • Where are features located on the earth? Equipment Examples:

  4. Physical Measurements of Earth Systems Four Major Earth Systems: Atmosphere Biosphere Hydrosphere Lithosphere

  5. Process Knowledge is important! Examples of specific types of physical measurements: Geomorphology requires knowledge of orogenesis and denudation processes Physical / Chemical Weathering Mass movement Erosion Techtonic Plate Movement Volcanism What physical measurements might a geomorphologist make? What tools might be used?

  6. How about other areas of physical geographic research? • Soils • Climate • Atmosphere • Hydro • Biogeography • etc……

  7. Physical Measurements in Human Geography • Accretion / Deletion / Modification • Physical Traces • Byproduct of use • Adaptation for use • Display of Self • Public Message Reactance can threaten the validity of results. Physiological / Neurological Measurements
