Question 4
4. Two students are debating the classification of graphite (chemical formula:
C). With which student do you agree?
Student 1: I think that graphite belongs in the "other" category. It has carbon,
but it doesn't have oxygen, so according to the definition, it cannot be a
carbonate.
Student 2: But the word "carbonate" has the word "carbon" in it! I think that if
any mineral has carbon in its chemical formula, it must be a carbonate.

Question 5
5. Examine Rock 3 in the
Lab Rock Kit
. Which one of the geologist’s groups
of minerals mostly makes up this rock? What observation did you use to
make your interpretation?
iron-rich silicates, because it is mostly dark in color
iron-free silicates, because it is mostly light in color
other, because it has shiny pieces in it

18b. For the picture you uploaded in the previous question, say what it is a
picture of, explain what mineral it’s made from, and give a key characteristic
of that mineral that makes it useful for its purpose. You may need to do some
research online in addition to your textbook and this lab to help you.

Your Answer:
I uploaded my kitchen counter and it is made from granite. I researched
some information about granite. Granite is mainly composed of several
minerals, with three main minerals being: Quartz, Feldspar, and Mica. Quartz
is a hard and durable mineral that appears as clear or white crystals. It gives
granite its strength and resistance to wear. Feldspar is a group of minerals,
commonly found in granite in the form of orthoclase and plagioclase feldspar.
Mica is another group of minerals found in granite, of which muscovite and
biotite mica are common types. It can range in color from silver to dark
brown or black.

Question 22
Your Answer:
21. Answer one of these questions using 3-5 sentences: What surprised you
most when you were completing this lab? OR What did you find most
interesting when completing this lab? OR How did information in this lab
relate to something you knew previously?
I was surprised by how variety and complicated of many kinds of minerals.
After this lab, I have learned that minerals have many amazing
characteristics. Also, before, I did not know that the timing of salt dissolving
would be different if we put salt in different kinds of temperatures of water.
So, after completing this lab, I have learned many useful things which are all
related to my daily life.
