Study the map extract on a scale 1:50,000 and answer the following questions (a) On the map (i) Write the letter in brackets over an example of each of the ...

(a) Marking features on the map

• (i) Knoll (K): print over a small isolated low hill shown by a few small closed contour rings. Sand deposit (SD): print over the stippled/dotted symbol along a river channel. Disappearing stream (DS): print where a blue stream line ends abruptly and the water sinks underground.
• (ii) Shading: shade clearly the area enclosed by the 925 ft contour in the north-east.

(b) In the answer book

(i) Length of the secondary road. Measured map length \(=28.0\text{ cm}\); scale 1:50,000, so

The secondary road is 14 km long.

(ii) Type of rock: limestone, because disappearing streams occur where water sinks through porous, jointed limestone.

(iii) Possible industry: a cement factory, if the limestone occurs in commercial quantity.

(c) Effects of relief and drainage

• (i) Communication pattern: roads avoid areas liable to flood and the many stream valleys, so roads are limited and footpaths are numerous; the secondary road in the north-east keeps to higher ground and avoids the river valleys.
• (ii) Settlement pattern: settlements are fewer in the west owing to the lack of surface water and are dispersed as people search for water; there are more settlements near the river valleys in the east, and settlements avoid areas liable to flood.

(d) Three possible occupations (with reasons)

• Fishing - the rivers and streams provide a ready supply of fish.
• Cattle rearing - the scrubland provides grazing for livestock.
• Farming - the scattered cultivation shown on the map indicates crop growing.
