Read the background information presented in this exercise, and study the minerals and rocks provided to fill in the blanks in the Properties of Rocks Table. Give the class as igneous intrusive (Ii), igneous extrusive (Ie), sedimentary (S), or metamorphic (M). List the crystal or grain size as microscopic (Mi) if the crystals or grains are too small to identify without a microscope, or macroscopic (Ma) if the crystals or grains are recognizable without a microscope.
Exercise: Fill in the properties of the following rocks provided in the rock and mineral kits.
Ii=igneous intrusive, Ie=Igneous extrusive, S=sedimentary, M=Metamorphic, Mi=microcrystalline, Ma=macrocrystalline.
