    Study Notes

    Geological Features and Processes

    • Oxbow lake is formed when a loop of a meandering stream is cutoff, leaving behind the remnant of the channel.
    • Braided channel consists of more than two streams of water that interconnect to form a network.
    • Terraces are step-like formations occurring when sediment is eroded and deposited along the banks of a river.

    Aquifers and Groundwater

    • Aquifers are underground water reservoirs that store groundwater like giant rock sponges.
    • An artesian well is made by driving a tube into the soil until it reaches an aquifer.
    • Permeability of an aquifer and the pressure of the water determine how fast water can move underground.
    • Unconfined aquifers allow water to exit through topographical depressions like valleys.
    • The highest classification for spring water discharge amount is an artesian well.

    Glaciers and Landforms

    • A calving glacier is formed when ice breaks off from a glacier and falls into water.
    • A kettle lake is a landform created when an area carved out by a glacier fills with water.
    • Glaciers move over obstacles and rough ground through a process called basal sliding.
    • The accumulation zone of a glacier is where snow and ice are added, and the ablation zone is where they are removed.

    Uniformitarianism and Geological Processes

    • Uniformitarianism is the concept that geological processes occurring today have shaped the Earth's landscape over time.
    • Runoff occurs when precipitation flows over the ground surface, and infiltration occurs when it seeps into the soil.
    • Permeability of rocks affects the rate of infiltration.
    • Geological processes involved in the formation of bedrock channels include erosion, transportation, and deposition of rock fragments.
