Questions and Answers

What are the three rock groups based on how the rocks form?

  • Igneous Rocks
  • Sedimentary Rocks
  • Metamorphic Rocks
  • All of the above (correct)
  • What are Igneous Rocks?

    Formed by the cooling and crystallizing of magma or lava.

    What are Sedimentary Rocks?

    Formed by the compacting and cementing of weathered/eroded rock particles (sediment).

    Study Notes

    Rock Groups

    • Three main groups of rocks: Igneous, Sedimentary, Metamorphic.

    Igneous Rocks

    • Formed from cooling and crystallization of magma or lava.

    Sedimentary Rocks

    • Created by compacting and cementing weathered or eroded rock particles.

    Metamorphic Rocks

    • Result from existing rocks transformed by heat and pressure.

    Geological Time Scale

    • Rock changes occur over long time frames, spanning thousands of years.

    Rock Cycle

    • Illustrates how rocks are formed and recycled through geological processes.

    Rock Transformation

    • Any rock can change into any of the other rock types through various processes.

    Conservation of Mass

    • The mass of Earth's rocks remains constant; they only change forms.

    Transformation Processes

    • Sedimentary Rock becomes Metamorphic Rock through heat and pressure.
    • Sedimentary Rock transforms into Sediment via weathering and erosion.
    • Sedimentary Rock turns into Igneous Rock by first becoming Metamorphic Rock, then melting to form magma, which cools into Igneous Rock.
    • Metamorphic Rock converts back to Sedimentary Rock through weathering and erosion.
    • Igneous Rock also transforms to Sedimentary Rock via weathering, erosion into Sediment, followed by compaction and cementation.
    • Igneous Rock can become Metamorphic Rock when subjected to heat and pressure.

    Magma and Rock Types

    • Magma turns into Igneous Rock through cooling.
    • Magma can become Metamorphic Rock, first cooling into Igneous Rock and then undergoing heat and pressure.
    • Magma transforms into Sedimentary Rock by cooling into Igneous Rock, which then erodes into Sediment and compacted.

    Sediment Formation

    • Sediment forms Sedimentary Rock through compaction and cementation.

    Melting Process

    • Igneous Rock transforms back into magma through melting.

    Rock Cycle Definition

    • The cyclical process of rocks changing from one type to another is known as the Rock Cycle.
