WAEC SSCE - Geography - 2013 (Essay)
Question 1 Report
(a) Define international track
(b) Describe any five benefits of international trade
(c) What four factors limit trade between African countries and the United States of America (USA)?
(a) Definition of international trade
International trade is the exchange of goods and services between one country and another across national boundaries. It consists of imports (goods bought from other countries) and exports (goods sold to other countries).
(b) Five benefits of international trade
- Provision of goods not produced at home: a country obtains raw materials, machinery and manufactured goods it cannot produce itself.
- Earning of foreign exchange from exports, which is used to pay for imports and finance development.
- Wider market for surplus produce: countries can sell their surplus goods abroad, encouraging greater production and specialisation.
- Promotion of specialisation and efficiency: each country concentrates on what it produces best (comparative advantage), raising output and quality.
- Fostering of friendship, cooperation and transfer of technology and skills between trading nations, and cheaper goods for consumers.
(c) Four factors that limit trade between African countries and the USA
- Similarity of exports: Africa mostly exports primary raw materials and the USA wants finished goods, so African countries have little the USA needs and cannot easily afford US manufactures.
- Long distance and high transport costs between the two, which raise the price of traded goods.
- Trade barriers such as high tariffs, quotas and strict quality standards imposed by the USA on African products.
- Weak currencies and shortage of foreign exchange in Africa, together with poor manufacturing capacity, limiting how much can be bought from the USA.
Also acceptable: differences in language/business practice, and unstable political conditions in some African countries.

Question 2 Report
(a) Outline four functions of an urban centre.
(b) Highlight four problems of urbanization
(c) Suggest possible solutions to any two of the problems identified in (b) above
(a) Four functions of an urban centre
- Administrative function: it serves as a centre of government, housing offices, courts and headquarters.
- Commercial function: it is a market and trading centre with shops, banks and business houses.
- Industrial function: it is a place of manufacturing where factories and processing plants are sited.
- Service function: it provides education, health, transport and recreation for itself and the surrounding region.
Also acceptable: cultural/religious, defence, mining, port or route-junction functions.
(b) Four problems of urbanization
- Housing shortage and growth of slums as people crowd into the city faster than housing can be built.
- Traffic congestion caused by too many vehicles and inadequate roads.
- Unemployment and crime as rural migrants fail to find jobs.
- Pressure on social services and pollution: water, electricity, schools, hospitals and waste disposal cannot cope, and the environment becomes polluted.
(c) Possible solutions to two of the problems
- Housing shortage: government and private developers should build more low-cost housing estates and high-rise flats, and provide site-and-service schemes and mortgage loans.
- Traffic congestion: construct more roads, flyovers and mass-transit systems (buses, rail), and encourage decentralisation of workplaces to reduce commuter pressure.

Question 4 Report
(a) Explain any five factors that are responsible for the population distribution in West Africa.
(b) Outline any five advantages of low population density in some parts of West Africa.
(a) Five factors responsible for the population distribution in West Africa
- Relief: lowlands, plains and river valleys are densely settled because they are easy to farm and build on, while rugged highlands are sparsely peopled.
- Climate and rainfall: areas with reliable, moderate rainfall attract dense settlement, while the very dry Sahel and desert margins and the excessively wet swamps repel people.
- Soil fertility: fertile alluvial and volcanic soils (for example the cocoa and food-crop belts) carry dense farming populations; poor, leached soils carry few people.
- Economic opportunities: mining areas, industrial and commercial towns and ports (Lagos, Accra, Dakar) draw large populations by offering jobs.
- Historical and social factors: long-established kingdoms, trade routes and safe, disease-free areas built up dense populations, while slave-raiding and disease (tsetse fly, river blindness) once emptied other areas.
Also acceptable: availability of water supply and good transport routes.
(b) Five advantages of low population density in some parts of West Africa
- Less pressure on land, so farmland, grazing and building space are readily available.
- Adequate food and resources per person, reducing the risk of shortage.
- Less environmental degradation such as deforestation, overgrazing, erosion and pollution.
- Reduced pressure on social services (schools, hospitals, water), so the few people are better served.
- Room for expansion and development, including large farms, ranching, forest reserves and future settlement, with less unemployment and congestion.

Question 8 Report
(a) Explain any five physical factors that hinder the development of railway transportation in Nigeria.
(b) Highlight any five ways transportation contributes to the economic development of Nigeria.
(a) Five physical factors that hinder the development of railway transportation in Nigeria
- Rivers and swamps: the many rivers (Niger, Benue) and the Niger Delta swamps require expensive bridges and embankments, raising construction costs.
- Highlands and rugged relief: the Jos Plateau, the Western and Eastern uplands and inselbergs force costly cuttings, tunnels and detours.
- Dense tropical forest in the south, which is difficult and expensive to clear for the line.
- Heavy rainfall and flooding in the wet south, which erodes embankments, washes out tracks and disrupts services.
- Loose and shifting sands and drought in the far north, together with laterite/hard rock in places, which make track-laying and maintenance difficult.
(b) Five ways transportation contributes to the economic development of Nigeria
- Movement of raw materials and finished goods between farms, mines, factories, markets and ports, promoting industry and trade.
- Opening up of the interior: roads, rail and waterways make remote farming and mining areas accessible for production and settlement.
- Encouragement of agriculture: farmers move perishable produce quickly to urban markets, raising incomes.
- Employment and revenue: the transport sector provides many jobs and generates government revenue.
- National integration and growth of towns: transport links different parts of the country, promotes tourism and helps towns grow at junctions and ports.

Question 9 Report
(a) Highlight any three advantages of each of the following modes of transport (i) Rail (ii) Water
(b) Give four reasons why some countries in Africa have not been able to sustain their rail transport
(a) Three advantages of each mode of transport
(i) Rail transport
- It can carry large, heavy and bulky loads (minerals, timber, farm produce) at low cost over land.
- It is fast and reliable over medium and long land distances and runs to a fixed timetable.
- It can reach interior areas away from the coast and is little affected by traffic on roads.
(ii) Water transport
- It is the cheapest means of moving very bulky, heavy goods over long distances.
- It needs no expensive track to be built on rivers, lakes and the sea (a natural highway).
- It can carry very large cargoes such as crude oil, grain and machinery in a single voyage.
(b) Four reasons why some African countries have not been able to sustain their rail transport
- Shortage of capital to maintain the lines, buy new locomotives and coaches and provide spare parts.
- Obsolete and worn-out equipment leading to frequent breakdowns, derailments and unreliable services.
- Poor management and inadequate skilled personnel to run and repair the system efficiently.
- Competition from road transport, which is more flexible and door-to-door, drawing passengers and goods away from rail.
Also acceptable: difficult relief and narrow-gauge/single-track lines, vandalism of rail property, and low, uneconomic traffic.
