c) Explain four problems facing railway transport in Africa. (8 marks)
❖ African countries use a different railway gauges which makes it difficult to have an integrated railway transport system/ transhipment of goods.
❖ Construction of railways requires large amounts of capital that most countries lack, either to extend or maintain the existing lines.
❖ Accidents/ vandalism/ uprooting of the railway line causes great losses/ delays in transportation.
❖ Tropical storm waters at times wash away vital sections of the railway lines thereby disrupting transport/ causes accidents.
❖ Railway transport faces stiff competition from the faster/flexible means of transport such as road and air transport hence under-utilization of railway facilities.
❖ Fuelling/ maintenance of railway stations and other related overhead costs are high thus reducing profit margins.

❖ There is a reflection of the sun rays on the water surface .
(ii) Describe how minerals are obtained using the mining method shown in the photograph.(5 marks)
❖ A mixture of water, solid/ mud and mineral particles is scooped from the water bed using a pan. Water is added if the mixture is thick/ if the water is excess it is decanted.
The material scooped is swirled in the pan.
This separates the lighter material from the heavier particles which contain the mineral particles.
The lighter material is removed/ poured out. The heavier materials are sorted to display mineral particles. The mineral particles are collected from the pan.
(iii) Citing evidence from the photograph, explain two ways in which the mining method shown has affected the environment. (4 marks)
❖ The scooping of materials has led to water pollution as indicated by the brown colour stagnant water which may make it unfit for people to use.
❖ The continuous scooping and dumping of the waste has led to land dereliction as indicated by the depression and heaps of waste material.
❖ The method has led to destruction of vegetation as miners cleared the land to acces the area with the mineral as indicated by absence of vegetation/ bare ground/ in the foreground/ middle ground.
❖ The method has led to loss of biodiversity/ destroyed the ecosystem as indicated by the absence of plant life where mining is taking place
(iv) Apart from the method shown in the photograph, name three other mining methods.(3 marks) :
(c) Explain how the following factors influence the occurrence of minerals: (i) evaporation; (2 marks)
❖ High temperatures in arid and semi-arid areas cause evaporation of water in lakes/ seas. This leads to high concentration of mineral salts in the water. Continued evaporation causes further recrystallization of the salts which may thereafter be attracted as minerals such as soda ash and common salt/ deposition of salts near the surface
(ii) vulcanicity; (2 marks)
❖ When molten magma intrudes into rock joints minerals contained in the magma embedded in the joints called veins. Such minerals as tin and copper occur in this form/ Hot springs/ geysers. Fumaroles bring minerals to the earth’s surface
(iii) metamorphism (2 marks)
❖ High pressure and heat cause recrystallization and hardening of certain rocks causing them to change their nature to and become minerals such as diamond.

❖ Areas that receive high reliable rainfall attract more people since they can engage in arable farming/ ares that receive low rainfall have fewer people as they are unsuitable for arable farming.
❖ Areas near water bodies attract dense settlements as the water is available for domestic/ industrial use /areas of scarcity water discourages settlement since it is difficult to get water hence low productivity.
❖ Areas with cool moderate temperature are densely settled as they can support agriculture / human life. Areas with extreme temperatures are sparsely settled as they are uncomfortable for human beings.
