    • D.

      Tourmaline

    • E.

      Halite

    Correct Answer
    C. Granite

    What are the three main categories of rocks?

    • A.

      Settled, swirled, and pressed

    • B.

      Gneiss, schist, and coal

      Hornblende, amphitite, galena

    • D.

      Sedimentary, metamorphic, and igneous

    • E.

      Compaction, extraction, and settlement

    Correct Answer
    D. Sedimentary, metamorphic, and igneous
    Explanation
    Categories help us classify and discuss rocks based on their characteristics. The other examples are either processes, do not apply to rocks, or are types of rocks and minerals.

    Rate this question:

  • 5. 

    Igneous rock is formed by

    • A.

      Magma that has cooled

    • B.

      Layers of particles cementing together

    • C.

      Rock changing from one form to another

    • D.

      Glaciers

    • E.

      Earthquakes

    Correct Answer
    A. Magma that has cooled
    Explanation
    Igneous rock is formed by cooled magma. Some igneous rock has large crystals, other has very small crystals, all depending upon the cooling rate of the magma.

    Correct Answer
    A. In a volcano
    Explanation
    Sedmimentary rock is formed where layers of minerals are allowed to build up over time. In a volcano, that process doesn't happen because of extreme heat, or lack of layering of particles.
