    Study Notes

    Processes of the Rock Cycle

    • Rocks can be transformed into different types through various processes: crystallization, erosion and sedimentation, and metamorphism.

    Crystallization

    • Magma solidifies into igneous rock by cooling either underground or on the surface.
    • Different minerals crystallize at different temperatures; for instance, olivine forms at higher temperatures than quartz.
    • The cooling rate impacts crystal size; slow cooling results in larger crystals.

    Erosion and Sedimentation

    • Weathering breaks down rocks into smaller fragments known as sediments.
    • Erosion involves the transportation of sediments by natural forces such as running water, ice, and gravity.
    • Sedimentation occurs when these sediments are deposited and accumulate.
    • For sedimentary rock formation, sediments must undergo compaction and cementation to bind together.

    Metamorphism

    • Rocks subjected to extreme heat and pressure within the Earth can metamorphose without melting.
    • Metamorphism alters both the mineral composition and texture of the original rock.
    • Resulting metamorphic rocks may exhibit new minerals and different textures compared to their predecessors.

    Key Processes of the Rock Cycle

    • Crystallization: Involves the cooling of magma, which can occur underground or on the surface to form igneous rocks.
    • Different minerals crystallize at various temperatures; for instance, olivine crystallizes at higher temperatures than quartz.
    • The cooling rate affects crystal size: slower cooling results in larger crystals.

    Erosion and Sedimentation

    • Weathering: Breaks down rocks into smaller pieces known as sediments.
    • Erosion: Transports sediments through forces such as running water, ice, and gravity.
    • Sedimentation: The process where sediments are deposited, forming sedimentary rocks through compaction and cementation.

    Metamorphism

    • Occurs under extreme heat and pressure without melting, altering a rock's mineral composition and texture.
    • Results in the formation of metamorphic rocks, which may exhibit new minerals or texture changes.

    Types of Rocks

    • Rocks are classified into three main types: igneous, sedimentary, and metamorphic.
    • The rock cycle illustrates how these types transform from one to another and how sediments evolve into rock.
