Dr. Sanders
By the end of
today's class, you should be able to do the following:
From last week...
* Respond
appropriately to the list of skills in
What
should you bring to this
course?
Rocks
* Name and give
concise definitions of the three major classes of rocks. For each
one, list subgroups and describe their formation and important
characteristics.
* Examining hand
samples of various types of rocks, construct reasonable hypotheses as
to how they formed; classify them according to your hypotheses.
* Suggest why
some of the specific properties of these rocks might be of importance
to a geotechnical engineer.
Discontinuities
* Describe the importance of discontinuities (bedding
planes, schistocity, folds, joints,
and fractures) in engineering analysis.
Sediments and Soil
* Considering
the different goals and purposes of geologists and geotechnical
engineers, write definitions of "soil", "sediment", and "rock" that
would be suitable for each group.
* Describe the characteristics of six different environments of soil
formation mentioned in the textbook.
(residual, glacial, alluvial, lacustrine, aeolian,
and colluvial soils)
Testing Your Knowledge
* Answer "Questions and Practice Problems", p. 32-33: Problems
2.1, 2.2, 2.3, 2.4, and
2.5.
* Answer
"Comprehensive
Questions and Practice Problems", p. 45: Problems
2.13 through 2.19. In answering the problem assigned to you,
discuss it first with a partner, then present to your colleagues the
following information:
--Location of the
study site
--Sketch of a
geologic cross section, plan view map, or other representation of the
important geological aspects of the situation.
--A brief summary
of the question/problem posed
--Your response
--Any further
geologic considerations that might be important.
