Review for Lab Exam 1 (Monday, Feb. 25, 2013). Here is a PDF version of the sheet provided by Dr. Gordon.
This Exam will begin at the start of lab and will include questions from the first three labs.
The lab will be open Friday and I have scheduled a review sesssion for you on Sunday night, so that you can review the minerals. See the review schedule.
Lab 1: Density, Isostasy & Plate Tectonics (you will be provided with a calculator and a ruler)
Lab 2: Maps and topography.
Lab 3: Minerals (you will be given streak plates and glass plates to use during the exam).
* Is this mineral metallic or non-metallic?
* Is this mineral harder or softer than glass?
* Is this mineral harder or softer than your fingernail?
* How many directions of cleavage does this mineral have?
* What color is the streak of this mineral?
*Note: You should be able to answer these questions for any mineral on the list (samples A - O). The samples for this portion of the exam will not necessarily be a mineral sample you saw in lab (i.e., minerals A–V).
*Hint: You do not need to memorize every property of every mineral; you only need to memorize each mineral’s distinguishing properties.
For Example: Hematite’s distinguishing property is that it is the only mineral that streaks red/brown. If you are given a sample on the test that streaks red/brown, then you know that it is hematite.
Warning: You will be given some A–O mineral samples that look different than the ones you saw during lab. Prepare for this by knowing the distinguishing properties of minerals A–O; Do NOT try to just memorize what the mineral samples look like.
