    What are minerals?

    Natural solid substances with a defined chemical composition.

    What defines igneous rocks?

    Formed from the solidification of molten material.

    How do sedimentary rocks form?

    Through accumulation and compaction of sediments.

    What is metamorphism?

    Transformation of rocks due to temperature and pressure changes.

    What is the difference between intrusive and extrusive igneous rocks?

    Intrusive rocks cool slowly underground; extrusive rocks cool quickly on the surface.

    What is lithification?

    The process of turning sediments into sedimentary rock.

    What are the main types of sedimentary rocks?

    Detrital, chemical, and organic.

    What is the Bowen's reaction series?

    A sequence that describes the crystallization of minerals from cooling magma.

    What characterizes metamorphic rocks?

    They exhibit foliation or banding due to pressure and temperature changes.

    What is the role of pressure in metamorphism?

    It can cause recrystallization and foliation in rocks.

    How do you classify igneous rocks?

    Based on mineral composition and texture.

    What is the significance of the mineral quartz?

    It is a common component of many rocks and is resistant to weathering.

    What are the characteristics of sedimentary rocks?

    They are layered and often contain fossils.

    What is the difference between clastic and chemical sedimentary rocks?

    Clastic rocks form from fragments; chemical rocks form from precipitation.

    What happens during the process of erosion?

    Rocks are broken down and transported by natural forces.

    What is a protolith?

    The original rock from which a metamorphic rock forms.

    What is the difference between gneiss and schist?

    Gneiss has banding; schist has pronounced foliation.

    What is the significance of the rock cycle?

    It describes the continuous transformation of rocks through geological processes.

    What are the conditions for the formation of metamorphic rocks?

    High temperature and pressure conditions.

    What is the main component of granite?

    It is primarily composed of quartz and feldspar.
