    Study Notes

    Earth Science Module 5: Rock Behaviors Under Stress

    • This module details how rocks react to different stress types (compression, tension, and shear).
    • Three main types of stress are covered: compression, tension, and shear.
    • Rocks can be deformed by various factors which will change its shape, size, and location.
    • Convergent plate boundaries are associated with compressional stress resulting in rock folding or fracturing.
    • Rocks are squeezed together at convergent plate boundaries, leading to mountain formation.
    • Divergent plate boundaries experience tensional stress, which pulls rocks apart.
    • Transform plate boundaries engage rocks with shear stress, creating sideways movement and fault lines.
    • Faults are cracks or fractures in rocks, and are categorized based on movement - normal, reverse, and strike-slip.
    • Normal faults occur at divergent boundaries when the hanging wall moves down relative to the footwall.
    • Reverse faults are common at convergent boundaries. These faults push one side up relative to the other.
    • Strike-slip faults occur at transform boundaries, characterized by horizontal slippage.
    • San Andreas Fault is an example of a strike-slip fault.
    • Metamorphism involves changes in rocks due to heat and pressure, altering their physical and chemical properties.
