  3. Soil Profile
    vertical sequence of of soil layers
  4. 4 main characteristics that make up a mineral
    • Naturally Occuring
    • Inorganic Solid
    • Definate Crystalline Structure
    • Specific Chemical Composition
  5. Crystal
    A solid in which the atoms are arranged in a repeating pattern.
  6. magma
    molten material found beneath earths crust
  7. 7 ways to identify a mineral
    Color, Luster, Streak, Cleavage & Fracture, Hardness, Density & Specific Gravity, And Texture
  8. Most abundant element found in earths crust?
    Oxygen
  9. Oxygen + Silicon = ?
    silicates
  10. How are IGNEOUS rocks formed...?
    crystallization of magma
  11. two types of igneous rocks
    • intrusive- coarse grained rocks. cooled slowly underneath earths crust.
    • extrusive- Fine grained rocks. cooled quickly on earths surface.
  12. sediments
    pieces of solid material that have been deposited
  13. how are sedimentary rocks formed.
    deposition burial & lithification
  14. meatmorphic rocks are formed by ________ & ____________
    heat & pressuree!
  15. two types of weathering?
    • mechanical- physical
    • chemical- composition
  16. exfoliation
    stripping away outter layers
  17. frost wedging
    water inside cracks, cold, freezes, ice expands, rocks crack even more
  18. 4 factors effecting chemical weathering
    water oxygen carbon dioxide acids
  19. hydrolysis , oxidation
    • the reaction of substances with water.
    • the reaction of substances with oxygen.
  20. depostition
    final stage of erosion process
  21. running water
    the most signifigant cause of erosian
  22. gravitys role in erosian
    w/o gravity, glaciers would not slope downward
  23. how does running water effect erosian?
    carries sediments
  24. wind erosian
    moves particles
  25. soil

  26. 3 characteristics of soil
    texture fertility color
  27. does poorly developed soil show little or great distinction between layers?
    little distinction
  28. 4 soil types
    • polar soils- high altitudes
    • temprate soils- support a diverse enviroment
    • desert soils- high level of accumulated salt
    • tropical soils- weathered and infertile
  29. soil fertility
