TO EARTH SCIENCE
By the end of
today’s class, you should be able to do the
Common Sedimentary Rock-Forming Minerals
* Review: Examine and
describe the properties of each mineral sample in the following groups,
and determine what each group
has in common. Finally, assign a name to each mineral using a
# 7, 17, 19, 20, 40,
# 2, 18, 30, 46
Third Group (if you have time): # 14, 33, 34, 44
* Describe each of the steps in forming sediments: weathering, transport, and deposition.
* Describe the process that changes sediments into rock (lithification).
* Tell what weathering
is, and explain the difference between chemical and mechanical (physical)
* List the four main processes that transport sediment.
* Describe what chemical
sediments are and how they form, using the terms dissolution and precipitation.
* List three main groups of detrital (clastic)
and tell how they are different based on their size.
* Using the list of common sedimentary rock-forming minerals that
appears above (you should have assigned names to each of the numbered
specimens listed above), tell how each is likely to play a part in
forming a sedimentary rock.
