  20. Guiding Principle #1:Conservation of … Mass http://exploration.grc.nasa.gov/education/rocket/mass.html Energy http://exploration.grc.nasa.gov/education/rocket/thermo1f.html Momentum http://exploration.grc.nasa.gov/education/rocket/conmo.html Course Notes: 1.3.1 A&A Chap. 1

  21. Guiding Principle #2:Transport Rules • Process Geomorph involves movement of material – ice, water, air, sediment, piles of rocks, etc. • Rates of material motion are influenced by stresses – e.g.’s: • Water flowing downhill: velocity increases with greater slope. • Compost decay rate increases with ambient temperature. • Rate of people entering a football game increases with internal crowd roar. Course Notes: 1.3.2 A&A Chap. 1

  22. Guiding Principle #2:Transport Laws Time scales of motion / rates for different materials can vary several orders of magnitude within the same environment: Ice Sheet example – katabatic winds, meltwater streams, glacial flow, mantle flow. Course Notes: 1.3.2 A&A Chap. 1
