SECTION A

1. Hydrology and fluvial geomorphology

Fig. 1.1 and Fig. 1.2 show catchment flows in a drainage basin system before and after urbanisation.

• 1. a) Calculate flow X in Fig. 1.1. (1 mks) b)Name flow Y in Fig. 1.2. (1 mks)
• 2. Using Fig. 1.1 and Fig. 1.2, describe the changes to catchment flows after urbanisation. (3 mks)
• 3. Explain why catchment flows change after urbanisation. (5 mks)

1. Atmosphere and weather

Fig. 2.1 is two photographs which show a type of precipitation

• a) Describe the characteristics of the type of precipitation shown in Fig. 2.1 (2mks)
• b) Briefly explain the formation of the type of precipitation shown in Fig. 2.1. (3 mks)
• c) Explain why the type of precipitation may vary in one location (5 mks)

1. Rocks and weathering

Fig. 3.1 shows the global pattern of tectonic plates.

• (a) (i) Name the type of plate shown as X in Fig. 3.1. (1 mk) ii)Name the type of plate boundary shown as Y in Fig. 3.1 (1 mks)
• b) Draw a sketch of plate boundary Z in Fig. 3.1. Label the main features. (4 mks)
• c) Explain the formation of one of the features you identified in (b) (4 mks).
