      • B-2212
      • D-2014
   2. Give SIX figure grid reference of points C and E. (4mks)

   • Use of Landmarks
   • Use of Heavenly Bodies
4. Identify methods of representing Relief on Topographical maps. (5mks)
   • Contours

   • Spot heights and Trigonometrical Stations
   • Hill shading
   • Colouring
   • Cliff and Rock drawing
5. Identify two types of Aerial Photographs. (2mks)

7. Identify three causes of Earthquakes. (3mks)
   • Tectonic movement
   • Vulcanicity
   • Isostatic adjustments
   • Human activities
8. Explain any three constructive consequences of Vulcanicity to Human Activities. (6mks)
   • The Volcanic rocks of the Kenya highlands have been weathered to produce fertile soil for agriculture.
   • Landforms resulting from activity are tourist attraction /scenic beauty e.g Mt Kenya.
   • Trachyte and phonolites/volcanic rocks are used for building
   • steams jets/gerious at Olkaria are used for generating geothermal power.
