Rock on Jeopardy

Rocks

100

what type of rock has grains and layers

Sedimentary

200

• How would you identify a metamorphic rock

• banded crystals, warped appearance, wavy lines, very compressed

300

New Rocks are formed from what?

Magma

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

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

Minerals

100

Name one thing a mineral is used for

• cars, jewelry, metal, powder, many things..

200

• Name one mineral characteristic you would use to describe fool’s gold

• Luster or shininess, cleavage or cut

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

400

• There are 7 main ways to identify minerals: Name them

• Mohs scale, luster, cleavage, specific gravity, color, streak and chemical composition

500

• What is the chemical composition of quartz

SiO2

Rock's story Earth Movement

100

• What is the theory that the earth moves along plates called:

• Plate Tectonics

200

• What plate boundary do you find natural gas and oil pockets?

• Transformation boundaries

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

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

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.

Mining

100

• Why do we mine?

• To extract minerals and fossil fuels from the earth for use

200

• What kind of mining is used to mine coal?

• subsurface mining

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

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.

500

• List the main types of mining

• Surface, Subsurface, Placer, Undersea and Smelting.  Fracking or Hydrolic mining is one too.

Identify that Rock

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

• What kind of rock is this?

Sedimentary

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

• 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

• What 3 characteristics would you use to describe this mineral? Explain

• cleavage, streak, luster, specific gravity, color, chemical composition, mohs hardness
