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)
