      General Geophysics and Physics of the Earth

       

      Old Exams

      Midterm 2000

      Final 2000

      Midterm 2001

      Final 2001

      Midterm 2002

      Final 2002

      There were no exams given in 2003 or 2004.

      These problems are intended to provide practice with vectors and taking components of vectors.

      Steady state and transient heat flow in the asteroid Vesta.

      Steady state heat flow in the asteroid Ceres.

      A heat flow problem based on cooking a turkey or other large item. Gives practice on scaling to mass.

      These problems involve heat loss from cyclindrical conduits. The conditions for hot material to ascend to the surface are examined.

      A short problem related to ground water flow and the heat flow paradox along the San Andreas fault

      San Andreas 1

      Another short problem distributed strain and the heat flow paradox along the San Andreas fault

      San Andreas 2

      Marine heat flow and global convection provide examples modeled has steady state conduction and convection. The effects of transient thickening of the lithosphere, transient cooling of the mantle, and the adiabatic gradient on heat flow within cratons are simply obtained

      Two problems deal with the issue of how a small near by object effects gravity, gravity gradient, and gravitational potential measurements. A spherical cow gets in the way of a survey.

      Corrections to gravity anomalies involve the before and after of a region covered by a lava flow. A buried lava tube is used as an example of the effects of changing the point of observation on anomalies.

      The Twin Sisters dunite provides an example of gravity interpretation in an area where the basement is exposed. The question is whether the dunite is a thin thrust sheet or a body that extends downward into the mantle.

      Combined modeling of gravity and magnetics for a basement feature buried beneath platform sedimens.

      Peak rebound from erosion of the Tibetan plateau and flooding of the Mediterranean Sea in the Miocene are used as examples of local and regional isostasy.
