3 Catholic Junior College 2018/2019 ANSWER SCHEME Section A - Tropical Environments Answer one question from this section. 1(a) Explain the erosional processes that take place in the arid tropics. Indicative content Students should explain processes of erosion by water (splash erosion, rainwash and rillwash) and by wind (deflation and abrasion) that occurs in the arid tropics. Better responses would be able to explain why these processes occur within the arid tropics. [12] (b) To what extent are erosional processes the dominant process affecting the development of landforms in the tropics? Indicative content Students should provide a well-evaluated evaluation discussing the extent to which erosional processes are the dominant process affecting the development of landforms in the tropics. This should be weighed against other processes such as weathering, mass movement, tectonic uplift, transportation/depositional processes by wind and climate change. Arguments should be well-exemplified. Overall stand should be consistent and well justified. Better responses would be able to discuss how the dominant processes would vary according to whether they are landforms in the humid tropics (karst landforms), or landforms in the arid tropics (yardangs, dunes and/or loess). [20] 2(a) Explain how the seasonal variation in wind direction influences precipitation patterns during the African monsoon. Indicative content Students should explain how the
