          1.2.5      Interfluve (2)                                                  (5 x 2)       (10)

1.3       1.3.1      It is a zone between two air masses with different moisture
                     content (2)                                         (1 x 2)                   (2)

          1.3.2      A   is the south westerly wind (2)
                     B   is the north easterly wind (2)                              (2 x 2)       (4)

          1.3.3      A   is cold (2)

          1.3.5      The cold dry south westerly wind and the warm north easterly wind
                     converge at the moisture front (2)
                     The cold, dry south westerly wind sinks whilst the warm, moist air
                     rises along the front (2)
                     Air will therefore cool and condenses forming cumulonimbus
                     clouds which will result in heavy rainfall along the front (2)
