  1. layers of the earth
    • crust/solid rock
    • mantle/liquid and solid
    • outer core/dense fluid
    • inner core/made of iron and nickel
  2. crust and upper mantle
    lithosphere
  3. the circular movement of heated materials in a cooler area.Heated air rises; cooler air sinks
    Convection Currents
  4. the study of how the lithosphere plates interact
    plate tectonics
  5. plates interact in three different ways;
    • convergent boundary ;push together
    • divergent boundary;pull apart
    • transform boundary;slip past each other
  6. the process in which rocks are gradually broken down
    weathering
  7. breakdown of large rocks to small ones(ex.- ice freezing in the rocks; roots craking the rock apart)
    physical weathering
  8. rocks decomposed, dissolved, or loosened
    chemical weathering
  9. when oxygen combines with another substance to break down
    oxidation
  10. when carbon dioxide dissolves in water
    carbonation
  11. no carbon
    inorganic
  12. contains carbon
    organic
  13. the exposed layer of the earth that contains the most minerals and nutrients
    topsoil
  14. the second layer of the earth that contains fewer minerals and nutrients
    subsoil
  15. the solid rock layer beneath the subsoil
    bedrock
  16. a crack in the earth's crust along which movement occurs
    fault
  17. healthy soil
    • a. color
    • b. presence of life
    • c. levels of moisture
    • d. temparture
    • e. amount of minerals
    • f. odor
  18. what two layers of the earth do convection currents occur
    outer core and mantle
  19. convection currents occur:
    because heated material rises,cools,then sinks back down
