    Study Notes

    Chemical Weathering

    • Chemical weathering works fastest in colder/drier climates

    Water Properties

    • Water held tightly to sediment grains is called adhesive water

    Salinity

    • Water with a salinity between 15 and 35 parts per thousand is considered normal marine salinity

    Groundwater

    • A permeable body of rock that contains and stores water underground is an aquifer

    Aquifer Characteristics

    • The largest aquifers occur in regions with abundant porous sediment, such as sand and gravel, over broad geographic regions

    Ocean Currents

    • Regular and predictable oscillations that occur with respect to the level of the world's oceans are tides
    • A current that develops parallel to the coast when waves approach a coast at an oblique angle and forward momentum is deflected is a longshore current

    Karst Features

    • A cavity in rock, produced by the dissolution of calcium carbonate and is large enough for a human to enter, is a cave
    • A feature that forms in a cave when water, containing calcium carbonate, comes out of solution to create a formation on the ceiling is a stalactite

    Wave Characteristics

    • The vertical measurement of a wave from its crest to the base is its amplitude
