5. Q5Short answer·2 marks
   Distinguish between residual soils and transported soils, giving one example of each.
   Show answer and step marks

   1. Residual soils are formed in situ by the weathering of the underlying parent rock and remain at the place of their formation.+0.5
   2. Example of a residual soil, any one of: black soil; red soil; laterite soil; or any other valid residual soil.+0.5
   3. Transported soils are carried away from their source by external agents like rivers, wind or glaciers and deposited elsewhere.+0.5
   4. Example of a transported soil, any one of: alluvial soil; wind-blown desert (sandy) soil; or any other valid transported soil.+0.5

   Answer: Residual soils form in situ from the underlying rock and stay there (e.g. black, red or laterite soil); transported soils are carried by rivers, wind or glaciers and deposited elsewhere (e.g. alluvial or desert soil).
