100

what type of rock has grains and layers

Sedimentary

100

Name one thing a mineral is used for

  • cars, jewelry, metal, powder, many things..
100
  • What is the theory that the earth moves along plates called:
  • Plate Tectonics
100
  • Why do we mine?
  • To extract minerals and fossil fuels from the earth for use
100
  • Is this a rock or mineral and why?
  • It is a mineral bc it is pure made of a specific chemical composition.  It is sulfur
200
  • How would you identify a metamorphic rock
  • banded crystals, warped appearance, wavy lines, very compressed
200
  • Name one mineral characteristic you would use to describe fool’s gold
  • Luster or shininess, cleavage or cut
200
  • What plate boundary do you find natural gas and oil pockets?
  • Transformation boundaries
200
  • What kind of mining is used to mine coal?
  • subsurface mining
200
  • What kind of rock is this?

Sedimentary

300

New Rocks are formed from what?

Magma

300
  • Talc and diamonds are at opposite ends of what tool used to identify minerals? Talc a 1, Diamond a 10

Mohs scale of hardness

300
  • Big continental rifts or ocean rifts where many minerals from magma are found are formed from what type of plate movement? On continental rifts evaporites form

Divergent

300
  • If you are mining for metal deposits you would use what type of mining?  describe it.
  • Placer Mining:  Putting deposits in a sand solution and panning out for the metal
300
  • Where is this rock formed?  How do you know?
  • Deep in the earth bc it has large crystals it is an intrusive igneous rock
400

List the two types of igneous rocks and characteristics of each

  • intrusive igneous: big crystals formed from slow cooling deep in the earth
  • extrusive igneous: surface cooling either quickly which is glassy obsidian or slow surface cooling with holy pumice
400
  • There are 7 main ways to identify minerals: Name them
  • Mohs scale, luster, cleavage, specific gravity, color, streak and chemical composition
400
  • Why should you study rocks and minerals? What does it tell you about the earth?
  • How old it is.
  • What movement has happened over time.
  • What the past looked like in that area.
  • to determine where to find different types
400
  • What is the name used to fix a mining spot after it is mined.  Give an example of how you could do this.
  • Reclamation.  Take the land back to its original state by reshaping the earth and replanting.  Underground bike park or natural park.
400
  • How would you tell which one of these minerals has a higher specific gravity? If I describe them could you guess which?
Specific gravity is how dense the mineral is.. so which one seems more heavy for its size


corundum is heavier

500
  • list the three rock types and what it takes to make each of them
  • sedimentary: erosion sediment cemented together
  • Metamorphic: heat and pressure
  • Igneous: magma cooling
500
  • What is the chemical composition of quartz

SiO2

500

In the Grand Tetons there are exposed rocks with large crystals in them.  Why are those rocks there?

  • Because of subduction on a convergent plate boundary pushed the earth up and exposed intrusive igneous rock from under the earth.
500
  • List the main types of mining
  • Surface, Subsurface, Placer, Undersea and Smelting.  Fracking or Hydrolic mining is one too.
500
  • What 3 characteristics would you use to describe this mineral? Explain
  • cleavage, streak, luster, specific gravity, color, chemical composition, mohs hardness
