In two or three sentences, describe the procedure you would follow to determine if one sample was gypsum, one was diamond, and one was quartz. State how you would make a decision.
outcrop means where does it appear on the surface, usually without having to dig, though some consider things like the walls of highway cuttings to be outcrop. If you see some bedrock sticking up out of a field, or some natural cliffs, that is an outcrop. Quartz is one of them most common minerals. you can see it in granite outcrops, and in sandstone sedimentary beds, where it exists as small crystals as part of the rock (usually has a grey/white glassy look to it). It can also form thick veins of white pure quartz that is deposited in other rocks. Because it is hard and non reactive, it tends to last while other rocks break down, so a lot of pebbles are of quartz. Also because of this, yellow beach sand is mostly quartz
well.....diamond is one of the hardest rock mineral thingys.......so....maybe using a diamond?
