2. Test topics: Meet in computer lab. minerals (five characteristics) tests geologists use to identify a mineral use of a mineral guide to identify a mineral rocks; how do they differ from minerals rock types general formation of each of the three types processes that construct or destruct rock sub-groups of each of the three types rock cycle identification of rock samples (group and sub-group only; knowing name of rock is extra credit – Do NOT put your focus there!)

3. Rock Type Review All Rocks sedimentaryigneousmetamorphic intrusiveextrusive clastic organic non-foliatedfoliated chemical remains of plant or animal Bits of sediment compacted (or cemented ) together Cooled lava; small or not visible mineral grains; some have no minerals at all and are called glass Cooled magma in crust; large visible mineral grains No visible layers or bands Heat and pressure cause minerals to line up in visible layers or bands minerals precipitated out of a solution

4. Rock Cycle Every rock type can become every other rock type eventually because the earth’s constructive and destructive processes repeat themselves continuously. Heat and pressure
