Can anyone answer these 7 questions about rock identification:
1) Why is it important to observe crystal size in igneous rock?
2) How did the minerals in the metamorphic rock get organized into bands?
3) Sand is made of quartz, and does not react to acid. How then, can we explain that some forms of sandstone react positively to acid?
4) What minerals are responsible for the dark color of basalt, an igneous rock?
5) How do intrusive rocks differ in origin from extrusive rocks?
6) How are polymineralic rocks different from monomineralic rocks? Give examples for each.
7) How are all rocks ultimately derived from magma?
