Question 1 Report
(a) (i) Draw an annotated cross profile from point A to point B.
(ii) Are points A and B intervisible? (Give one reason for your answer)
(b) In what three ways has the relief affected the transportation network of the mapped area?
(c) Give any two reasons why the area mapped is sparcely populated.
Answer Details
(a) (i) Annotated cross-profile from A to B
(ii) Points A and B are not intervisible. The intervening hills rise above the line of sight between A and B and therefore obstruct visibility.
(b) Effects of relief on transportation
- The area is mainly upland; consequently, road construction is difficult and transport routes are few.
- The rugged hills in the western and northern parts discourage the construction of roads and other transport lines.
- The less rugged eastern and south-eastern part permits a secondary road, while footpaths are few and widely spaced in the high-relief areas.
(c) Reasons for sparse population
- The western and northern parts are rugged, high and inaccessible; hence, there are few or no settlements there.
- Farming is difficult on the high, steep and rugged land, so few people settle in the area.
