view soil differently: ecological, geological, environmental, etc.
Parameters related to soil...
What is the origin of the sediments that ultimately formed the parent materials for Florida
soils?
✓ -:- An influx of continental sediments began about 25 mya; the sediments were
shed from the Appalachian mountains by the lowering sea levels
How do rainfall and temperature impact soil formation?
✓ -:- Increased temperature and rainfall both accelerate soil formation.
High temperatures increase the rate of physiological processes (microbial activity,
organisms) while water increases the rate of weathering and translocation, ultimately
increasing the rate of transformation.
Why are soils in Florida more developed compared to soils in the west?
✓ -:- In the east there is more rainfall, causing faster weathering and soil
transformation. This causes more differentiated soil horizons.
What is pedogenesis?
✓ -:- The process of soil formation as a result of the combination of soil forming
processes mediated by soil forming factors
