Answer 1

12. Ans- The illustration shown is of normal faulting, shear stress and horst and graben structure. The structure shows the faults in the area and its movement along some direction The hanging walls wall appears to rest on the footwall showing normal faults and thus the application of shear stress on it. The footwall appears to move up in succession of it forming horst and the creation of graben graben again. This shows the horst and graben structure.

Compression and extension are normally associated with folds.

14 Ans- All the options indicated above in the question are the result of convergence. Eruption of basaltic lava will take place along the trenches where subduction takes place. The difference in pressure will lead to the precipitation of sedimentary rocks and deposition of layered clastic sedimentary rocks along the island arcs formed nearby. Since convergence is the net effect of motion to destroy surface area, it leads to the development of metamorphic rocks.
