    2. Baway from the axial trace and the oldest rocks are at the center
    3. Ctoward the axial trace and the oldest rocks are at the center
    4. Dtoward the axial trace and the youngest rocks are
       at the center

    1. Aaway from the axial trace and the youngest rocks are at the center
    2. Baway from the axial trace and the oldest rocks are at the center
    3. Ctoward the axial trace and the oldest rocks are at the center
    4. Dtoward the axial trace and the youngest rocks are at the center
12. 12Rock layers exposed to surface in a zig-zag manner would imply the presence of

    2. Basymmetrical folds
    3. Coverturned folds
    4. Drecumbent folds
    5. Eplunging folds
13. 13The East African rift and other major rifts are a result of

    1. Aan extension of the crust
    2. Ba compression of the crust
    3. Can overthrust
    4. Da shear movement of the crust
14. 14The topography of the Basin and Range Province that encompasses Nevada and portions of the surrounding states has been generated by a system of north to south trending

    1. Anormal faults
    2. Breverse faults
    3. Cright-lateral strike-slip faults
    4. Dplunging folds

    3. Cfolded structure
    4. Dbasin structure with reversal of topography due to differential erosion
16. 16In rocks, joints with orientations nearly perpendicular to the surface can be produced by

    1. Aremoval of pressure as deeply buried rocks are exposed to the surface
    2. Baddition of loads on rocks when they are very deeply buried
    3. Ctensional stresses when rocks in the crust are folded
    4. Dmelting of overlying glaciers
17. 17Loch Ness, the home of a mythical monster, in Scotland is situated on a

    1. Anormal fault
    2. Breverse fault
    3. Cseries of joints
    4. Dleft-lateral strike-slip fault
18. 18In an area, the same rocks appearing in the form of parallel ridges would imply

    1. Aa series of folds with their axes nearly horizontal
    2. Ba series of fault scarps that separate the ridges
    3. Can intrusion of a large body of magma
