PART I  PHOTOGRAPHS

You must take photographs around Long Island (large erratics, roads,
 sidewalks,cemeteries) which illustrate the various types of physical and 
chemical weathering.  You must take  two different photographs of
  each of the following:

A. FROST ACTION
B. ROOT WEDGING
C. SOLUTION (best seen on brick buildings)
D. OXIDATION (be careful, don't confuse lichen with rust)

A WORD OF CAUTION: To receive credit, your photographs must
 clearly show the effects of the agent of weathering in question.  So 
make sure it’s great ! Each photograph must be clearly labeled, giving 
the location and explaining what it shows.


PART II  EFFECTS OF EXPOSURE

You must visit a cemetary and find at least 5  tombstones which are four 
sided. Examine each of the tombstones and record your observations 
about how each side of each one is weathering. Put your observations 
in a datatable.  Which of the sides seems to 
have weathered the most. Or, are they the same ? Include two pictures
 which best support your onclusion.     Based on your observations, 
make a conclusion (in essay form) concerning the effect of direction of 
exposure on the weathering 
rate and/or type.  Be sure to include your observations.

NOTE:
YOU MUST BE IN ALL PHOTOGRAPHS TO RECEIVE CREDIT.



All of the above should be arranged in a typed report.
