Objectives #9 (September 26, 2006)
By the end of today’s class, you should be able to do the
* Examine and describe the properties of the common minerals that
occur in sedimentary rocks.
* Explain what samples 7, 17, 19, and 20 have in common.
* Explain what samples 18, 21, 30, and 35 have in common.
* Examine and describe the properties of the hydrothermal
minerals that occur in sedimentary rocks. (Examples to be used in
class: sample numbers 8, 14, 33, 34, 44.)
* List and describe the two main categories of weathering (chemical weathering
give a few examples of each type.
* Explain the steps in forming deposits of sediments,
erosion, transport, and deposition.
* Distinguish between chemical sediments and detrital sediments,
describing characteristics of each category and telling how they form.
* Explain the difference between gravel, sand, and clay
sediments. [We did not do this
today; see Thursday 9/28/06.]
* Explain the steps in forming sedimentary rocks
correctly using the term lithification.
* Examine hand samples of sedimentary rocks, describe their
and use a key to identify their names. [We looked at but did not fully describe
sedimentary rocks today; see Thursday 9/28/06.]
