Minerals
Which mineral is used to make ore of iron and jewelry?
Hematite
Which rock has a map symbol with black and white stripes?
Gneiss
What is the composition of Bituminous coal?
Carbon
True or False, Basalt rocks formed Intrusively?
False
True or False, rocks are continually changing?
True
Which mineral contains the element CaF2?
Which rock has the lowest grade metamorphism? (Slate, Gneiss or Schist)
Slate
What are the two main classifications for sedimentary rocks?
Inorganic Land Derived and Chemically and or Organically formed
What is the texture of the Igneous rock, Gabbro?
Coarse
Compaction and/ or cementation forms what type of rocks?
Sedimentary
Which mineral is white to pink?
Potassium Feldspar
Selenite Gypsum
Explain the type of metamorphism that forms Hornsfel rocks.
It goes through contact metamorphism. Contact metamorphism occurs when a rock is heated up by an intrusion of hot magma.
How are rock salt and limestone different?
Rock salt is made of Halite and Limestone is made of calcite
Which Igneous rock is made up of Pyroxene, Plagioclase Feldspar, Biotite, Amphibole and Olivine?
Basaltic Glass, Scoria, Vesicular Basalt, Basalt, Diabase Gabbro
Weather of a rock results in what?
Sediments
Which of these minerals is the hardest? (Quartz, Pyrite, Garnet or Olivine)
Garnet
List the metamorphic rocks in order of increasing heat and pressure?
Slate, Phyllite, Schist and Gneiss
Which Sedimentary rock is 0.0004cm to 0.006cm?
Siltstone
What is the crystal size of the Igneous rock scoria?
Non crystalline
Fill in the blank.
_________ Gneiss
_________ Schist
_________ Marble
Fordham Gneiss
Manhattan Schist
Inwood Marble
Name three minerals that can be used to build a school and the specific materials.
Selenite Gypsum-Plaster/Drywall
Muscovite Mica-Construction Materials
Biotite Mica-Construction Materials
What would result if limestone went through regional or contact metamorphism and why?
It would result in marble due to the increase of heat
What do the following Sedimentary rocks have in common? (Conglomerate, breccia, sandstone, siltstone and shale
They are inorganic land derived.
They are composed of quartz, feldspar, clay minerals, etc.
Which igneous rock only contains one mineral and what is that mineral used for?
Dunite
Olivine is used for furnace bricks and jewlery
What the 4 different ways rocks can be eroded?
Wind, Water, Ice (Glaciers), and Gravity
