Unit C What Do You Know Now?

At the beginning of this unit you agreed or disagreed with statements about minerals and rocks. Not all of the statements were true. Now that you have completed the unit, carefully think about each statement again then decide whether you agree or disagree with the statement based on what you have learned. How many of your responses changed?

  1. Coal is an example of a common mineral. (Agree / Disagree)

    All minerals are made from inorganic substances. Coal is not a mineral because it is composed of the remains of ancient plants which are organic substances. See "C1 - Minerals: Building Blocks of Rocks / Characteristics of Minerals" for more information.
  2. The hardness of a mineral is a measure of the ease with which the surface of a material can be scratched by that mineral. (Agree / Disagree)

    See "C1 - Minerals: Building Building Blocks of Rocks / Properties of Minerals" for more information.
  3. The Earth's interior is the original source material for all rocks on the Earth's surface. (Agree / Disagree)

    See "C2 - The Rock Cycle / The Three Types of Rocks" for more information.
  4. Rocks, once they have been formed, usually remain fixed in form over time. (Agree / Disagree)

    The Rock Cycle describes the process by which rocks can be transformed over time. See "C2 - The Rock Cycle / The Rock Cycle - The Basic Cycle" for more information.
  5. Marble is produced from the transformation of limestone. (Agree / Disagree)

    See "C3 - Igneous, Sedimentary, and Metamorphic Rocks / Types of Metamorphic Rock" for more information.
  6. Acid rain can cause significant chemical weathering. (Agree / Disagree)

    See "C4 - Weathering and Soil Formation / Chemical Weathering" for more information.
  7. Climate is not a major factor in the rate of weathering. (Agree / Disagree)

    The climate of an area, particularly its temperature and rainfall patterns, can have a significant effect on weathering. See "C4 - Weathering and Soil Formation / Rates of Weathering" for more information.
  8. Soil is a major product of weathering. (Agree / Disagree)

    See "C4 - Weathering and Soil Formation / Soil Formation" for more information.
