Compared with that in the rest of Antarctica, weathering and soil-forming processes in the maritime Antarctic are relatively strong. It is demonstrated that frost weathering is the dominant form of physical weathering processes and has significant effect on rock disintegration and regolith formation in the region. And, in the maritime Antarctica, various modern periglacial processes play an important role in weathering, material transportation and soil formation. Besides, chemical weathering processes, including modes, mechanisms and products, are outlined in this paper. Meanwhile, it is pointed out that biological factors are quite active and have significant influences on rock-weathering and soil-forming processes.
