    MARINE BIOLOGY HOMEWORK HELP please (rep/thanks)

    I've been very busy lately..i apperciate you CK'ers helping me out.
    Ill rep/thanks if i can.

    The asthenosphere ___
    1) occurs only in the vicinity of the subduction zones
    2) lies above a flud lithosphere
    3) drives plate motion

    MATCHING
    A) Convergent Plate Boundary Diveregent Plate Boundary C) Transform Plate Boundary

    1) Continental collisions
    2) Mid ocean ridges
    3) Deep focus earthquakes
    4) Mid-ocean ridges
    5) Rift Valleys
    6) Shear stress fault lines
    7) Subduction Zones

    A)Continental Crust Colliding with Continental crust Continental Crust Colliding with Oceanic crust
    C)Not a case of plate convergence

    1)Alps
    2) Andes Mtns.
    3) Cascade Mtns.
    4) Hawaiian Islands
    5) Himalayan Mtns
    6) Mt Saint Helens

    The asthenosphere __3) drives plate motion
    1) occurs only in the vicinity of the subduction zones
    2) lies above a flud lithosphere (WRONG) Asthenosphere lies below Lithosphere http://en.wikipedia.org/wiki/Asthenosphere 2nd line.
    3) drives plate motion http://en.wikipedia.org/wiki/Asthenosphere (RIGHT) involved in plate tectonic movement and isostatic adjustments 2nd paragraph.

    1) Continental collisions (A) - Convergent Plate Boundary
    2) Mid ocean ridges ( B ) - Diveregent Plate Boundary
    3) Deep focus earthquakes (A) - Convergent Plate Boundary
    4) Mid-ocean ridges ( B ) - Diveregent Plate Boundary
    5) Rift Valleys ( B ) - Divergent Plate Boundary
    6) Shear stress fault lines (C) Transform Plate Boundary
    7) Subduction Zones (A) - Convergent Plate Boundary

    ================Not really sure about the following============= Need to reconfirm

    1) Alps (B ) Continental Crust Colliding with Oceanic crust
    2) Andes Mtns. (A) Continental Crust Colliding with Continental crust (Nazca plate with the South American plate collision)
    3) Cascade Mtns. (B ) Continental Crust Colliding with Oceanic crust (The Juan de Fuca Plate is moving under the North American Plate)
    4) Hawaiian Islands (C) Not a case of plate convergence
    5) Himalayan Mtns (A) Continental Crust Colliding with Continental crust
    6) Mt Saint Helens (B ) Continental Crust Colliding with Oceanic crust
