    Study Notes

    Granite Characteristics

    • Granite is a coarse-grained igneous rock
    • Granite is composed of quartz, feldspar, mica, and other minerals
    • Granite is commonly found in mountainous regions

    Limestone Formation

    • Limestone is formed through a process called sedimentation
    • Limestone forms from the accumulation of calcium carbonate shells and skeletons of marine organisms
    • Over time, these organic materials solidify and become sedimentary rock

    Marble Characteristics

    • Marble is a metamorphic rock
    • Marble is formed from the transformation of limestone under heat and pressure
    • Marble is known for its smooth surface and varied color palette (white, grey, black, and others)

    Smooth and Colored Rock

    • Marble is a smooth rock
    • Marble can vary in colour, ranging from white to black

    Common Feature of Sedimentary Rocks

    • Sandstone and limestone are sedimentary rocks
    • They are formed from the accumulation and cementation of sediments
    • This process creates layered structures within these rock types
