Some famous lines of latitude south of the equator are the Tropic of Capricorn (23.5 degrees south) and The Antarctic Circle (66.5 degrees south). North of the equator are the Tropic of Cancer (23.5 degrees north) and the Arctic Circle (66.5 degrees north).
A fault scrap is a small offset of the ground surface moves vertically with the respect to the other and the faulting is attributes to the displacement of the land with the movement along the faults and is indicated by the consequent erosion along the geologic faults. They are hard and weak rocks and the scrap formation is equal to the vertical weight displaced.
