Rocks and Minerals

Stacey’s teacher gave the class a mixture of rocks and mineral to observe. The class was asked to construct an explanation of why the object of their choosing cannot be considered a mineral. Which statement best explains why coal is not considered a mineral? (2a, DOK 2)

• Coal is not a mineral because it comes from organic materials and does not have a crystalline structure.

• Coal is not a mineral because it is inorganic and it is not naturally occurring.

• Coal is not a mineral because it is inorganic and it is naturally occurring.

• Coal is not a mineral because it comes from organic materials and has a crystalline structure.

Using the MOHS scale, list the following minerals in order of increasing hardness: apatite, calcite, corundum, feldspar, and talc. (2a, DOK 2)

• corundum, feldspar, apatite, calcite, talc

• apatite, calcite, corundum, feldspar, talc

• talc, calcite, apatite, feldspar, corundum

• talc, feldspar, corundum, calcite, apatite

How are the grooves in the rock formed? (2b, DOK 1)

• Mineral deposits compressed over years.

• Flowing magma that cooled at different speeds.

• A rapid rise in the water level.

• Uneven deposition from crystallization.

  Particles are compacted and cemented into new sediment rock.

• Wind and water move and help the sediment particles collected.

  High heat and pressure compact large rocks into sediment.

  Particles are melted and cooled into new sedimentary rock.

• High heat and pressure compact large rocks into sediments.

Areas prone to high winds are most likely to have which type of rock? (2b, DOK 2)

• Sedimentary rock, formed when metamorphic rock is exposed to high temperatures and pressure.

• Sedimentary rock, formed by the compacting of weathered sediment particles into layers over time.

• Metamorphic rock, formed by the cementing of weathered sediment particles into layers over time.

• Metamorphic rock, formed by the compacting of weathered sediment particles into layers over time.

Using the data chart below, how do minerals contribute to rock composition? (2a, DOK 2)

• Minerals such as Feldspar and Mica compose a Limestone Sedimentary Rock.

• Minerals such as Pyroxene and Quartz compose a Granite Igneous Rock.

• Minerals such as Calcite and Quartz compose a Metamorphic Rock.

• Minerals such as Granite and Basalt compose a Intrusive Igneous Rock.

• Organic, Man-made, Solid, Definite Chemical Composition, Crystal Structure

• Inorganic, Naturally Occurring, Solid, Definite Chemical Composition, Crystal Structure

Metamorphic rocks can be converted into a sedimentary rock by first undergoing which of the following processes? (2b, DOK 1)

• weathering and erosion

• cooling and crystallization

• heat and pressure

• compaction and cementation

A scientist finds a rock sample and wants to test its cleavage. Which action should the scientist do to test the cleavage??

• Dip the rock in water to see if it dissolves.

• Heat the rock to see if it melts.

• Use a microscope to examine the rock's surface.

• Break the rock along its natural planes or lines of weakness.
