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 following features: a Knoll(K), a sand deposit (SD), a disappearing stre (DS),
(ii) Shade clearly the area in the northeast, above 925 feet
(b) In your answer book:
(i) Calculate the distal of the secondary road in the map
(ii) Suggest the type of rock that dominates the region of disappearing stream What is the possible industry that may be sited in the region if the rock is found in commercial quantity?
(c) Describe the effects of relief and drainage of the mapped area on the
(i) communication pattern
(ii) settlement pattern
(d) Suggest with reasons, three possible occupations of the people in the area
(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
\[\text{Distance}=\frac{28.0\times50000}{100000}=14\text{ km}.\]
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.
