I recommend that you look over the answers to the in-class questions and think about your labs as well as lecture.
Things you should know: atom, nucleus, that in a neutral atom the number of protons (positive charges) equals the number of electrons (negative charges). That to be happy, an atom wants full shells. Also know what is meant by cation, anion, polymorph.
The most common mineral in the Earth's crust is a feldspar, and it is made of the three most common elements (oxygen, silicon, and aluminum). It is the only one of the silicates that we studied that has an element other than silicon in the tetrahedral site (aluminum is in some of the sites). This allows plagioclase to go from calcium-rich to sodium-rich by a coupled substitution of an aluminum for a silicon at the same time.
You should know what the words crust, mantle, lithosphere, and asthenosphere mean. You should know the three types of plate boundaries and what feature(s) is/are found at each type of plate boundary.
You should understand how we use hot spots to determine past plate motions and that plates do not keep moving the same direction at the same speed for long long periods of times.
You should know what the words, chondrule, accretion, differentiation mean.
You should know the defintions of the following mineral properties: pleochroism, cleavage, specific gravity, crystal habit, hardness, luster, streak, reaction to acid.
Look over your mineral charts. You will be asked about the following minerals in terms of their properties: olivine, pyroxene, amphibole, muscovite mica, biotite mica, potassium feldspar, plagioclase feldspar, quartz, calcite, halite (sodium chloride), hematite, and limonite.
