    Study Notes

    Rates

    • A rate is a measure of how something changes or occurs over a certain period of time or distance.
    • Rates can be expressed as a ratio of two quantities, often with different units.
    • Examples of rates:
      • Speed: distance per unit of time (e.g. km/h)
      • Rate of change: change in quantity per unit of time (e.g. meters per second)
      • Flow rate: volume per unit of time (e.g. liters per minute)
    • Rates can be calculated using the formula:

    Rate = Change in Quantity / Time

    Bedmass

    • Bedmass is a concept used in geology and sedimentology to describe the total amount of sediment deposited in a particular area over a given period of time.
    • It is often measured in units of mass per unit area (e.g. kilograms per square meter).
    • Bedmass is an important concept in understanding sediment transport and deposition processes.
    • Factors that affect bedmass include:
      • Sediment supply: the amount of sediment available for deposition
      • Current velocity: the speed at which water or wind carries sediment
      • Depositional environment: the type of environment in which sediment is deposited (e.g. river, ocean, desert)
