Study Notes
Soil Forming Factors
- Five primary factors that influence soil formation: Climate, Relief (Topography), Organisms (Biota), Parent Material, and Time.
Climate
- Impacts soil formation through precipitation and temperature.
- Influences the degree and rate of weathering.
- Extremely cold or dry conditions slow down soil formation processes.
Relief or Topography
- The position and shape of the landscape significantly affect soil properties.
- Different elevations result in varying moisture levels and erosion rates, which shape soil characteristics.
Organisms or Biota
- Includes the variety of plant and animal life in an area, like forests versus grasslands.
- The effects of climate and biota on soil are interconnected and often difficult to distinguish.
Parent Material
- Represents the geological material from which soil develops.
- Includes consolidated bedrock and unconsolidated deposits as primary sources for soil.
Unconsolidated Deposits
- Composed of loose materials that contribute to soil formation.
- Examples include:
- River or lake sediment
- Glacial tills and moraines
- Volcanic ash
- Talus (rock debris)
Time
- Refers to the duration over which soil has developed and the extent of profile formation.
- Longer time frames typically lead to more mature soil.
Soil Age Classification
- Soils can be classified as young, mature, or old, depending on the time factor in their development.
- All classifications (young, mature, old) are applicable to different soils, indicating the diversity of soil age.
