Chapters 10 - 14; no 13 - Coggle Diagram

- - - - infiltration to runoff ratio:
        High ratio: water recharging aquifers and is purified
        Low ratio: water movement toward ocean, not as usuable
  - - - groundwater issues: overwithdrawal and reduced recharge, loss of water to surface water, pollution, land subsidence, saltwater intrusion near the coast
- - - - parent material: transports and breaks down to form soil, can be organic or geologic
      - topography: a.k.a. relief, affects water movement and soil erosion, rocks and soil can move downhill by gravity, summits vs. slope soils differ
      - biota: flora (plants) and fauna (animals), help form SOM, cycle nutrients, facilitate weathering of rocks/ minerals, enhance infiltration, mix soil (bioturbation)
      - time: soils form over long periods of time, primary minerals weathering to secondary and become physically smaller, can take 100s of 1000s of years to form, young vs. old soils differ in appearance
      - climate: most influential, determines intensity and types of weathering that occur, 2 main climatic variables = precipitation and temperature
