    Study Notes

    Weathering Processes

    • Water is the principal agent responsible for both physical and chemical weathering.
    • Physical weathering occurs through the mechanical effects of heat, water, ice, and other natural agents, breaking down rocks and soils without altering their chemical composition.
    • Chemical weathering involves changes in the minerals within rocks, leading to dissolution or alteration due to chemical reactions.

    Erosion and Transportation

    • Erosion is the process that involves the transport of rocks and minerals by agents like water, ice, snow, wind, waves, and gravity.
    • This transport contributes to the reshaping of landscapes by moving materials from one location to another.

    Weathering Outcomes

    • The combination of weathering processes, erosion, and re-deposition results in sediment formation, which contributes to the development of new geological features.

    Sedimentary Cover

    • Sediment covers approximately 66% of the Earth's continents and vast areas of the ocean floor.
    • This sediment is formed from the weathering products of older rocks, leading to the creation of different types of sedimentary layers.
