This is because the weight of the atmospheric air at low altitude is more than at high altitudeii In summer, coastlands are relatively cooler than in land areas. This is because thewinds bring the cooling effect of the sea to the land, by the time winds reach inlandthey are heated by warm land resulting in higher temperature over the interior ofthe landIn winter the onshore winds bring the warming effect of the sea into the land causing a rise in temperature. By the time these winds reach the interior of the land, they are cooled by cold land thus enhancing the low temperatureOnshore winds cause a lot of rain in the coastal areas throughout the year. This is because the wind picks up moisture over the sea and drop it on the nearby land. The continental interiors receive less rain, mainly in summer, because the winds have dropped mot of the moisture in the coastal landsiii Ocean currentsCold ocean currents bring about the cooling effect in the temperatureAlso bring a dry effect because the cold air is not able to riseWarm ocean currentsBring a warm effect rise in temperature Heavy rainfall because the warm air is able to rise and condense to form rainfall.

21. TRANSPORT AND COMMUNICATION1. A i Demand- Availability of infrastructure- Topography terrain- Capital availability- Political factor- Historical factors- Climateii Difficult terrain This makes it difficult to develop transport and communicationi.e the great rift valley, the rugged scarps inselberg and numerous rocks out crops- Harsh environments e.g. Sahara desert and many isolated others- The harsh desert climate associated with low population. Suvch makes ituneconomical to construct the transport and communication facilities- Non navigable riversThis is due to1. Fluctuating water levels2. Presence of rock outcrops3. Rugged terrain i.e. many rivers have rapids waterfalls b i A L. MichiganB L. HuronC L. Erieii - To provide cheap water transport for bulky commodities like coal and iron ore toindustrial centres around the great lakesTo shorten the route to external markets especially for wheat from Canadian prairies and manufactured goods from the Great lakesTo expand manufacturing industries along the entire route, provide employment and develop townsIncrease agricultural production and tourismOpen up this part of America for international tradeTo easy strain on American railwaysTo increase HEP production along parts of the Seaway e.g. at Niagra waterfall and at dams constructed along the routeiii The long sault and Lachine rapids between Ontario and Montreal hinderednavigation. Aterfalls e.g. Niagra was preserved for HEPand tourist attraction. Thiswas solved by construction of alternative route i.e. Welland canala- Shallow ports e.g. Montreal that could not handle large ships they were dredged anddeepened- Problems of trans- shipment along the seaway causing delay. Seaway has beenwidened to accommodate large ships and these can now sail through the waterway without stoppingc - Reduces deterioration of Nairobi Mombassa highway due to reduction of tankers-Has reduced cases of accidents especially on Nairobi Mombasa highway- Very fast and convenient means of transporting such highly risky products since the products are firmly sealed in the pipe- Less labour used after installations i.e.

The sea way is a tourist attraction which generate income in the region. Employment opportunities have been created in the transport industry thus raising the living standard of the local people. The lakes and the dams are a source of water for both domestic and industrial use. The two countries earn some revenue from toll charfes levied on ships that use the routec - Communication enhances tradeMany people are employed in the communication sector. It promotes international and domestic tour ism. Governments disseminate information through the media. Communication promotes international understanding which lead to increased trade thus boosting economic development. -. African governments do not have adequate capital for modern transportequipment system. Stiff competition from well established air lines in the developed countries. High insurance cost of planes discourages investment in air transport. Mismanagement of African national air lines incur huge losses. Some regions in Africa are not served by direct flights and thus increases the cost of travelling to passengers. Small low volume of passengers and cargo makes it expensive for some airlines to operate. Insecurity in some parts of Africa is also discouraging the use of air transport. 3. A Communication is the exchange of information, ideas a, messages or opinions amongpeople. B - Liberalization of airwaves licensing of more private radio stations TV stations. Introduction of the fiber optic cable to enhance communication via internet e-mail fax telefax Licensing many companies to provide cell phone services. Liberalization of the press. Expansion of telephone facilities. Liberalization of postal services. High competition from faster and more efficient electronic mail. High cost of installation. Vandalism of telephone equipment. MismanagementPoor reception overlapping of telephone line. 3. C - High competition from faster and more efficient electronic mail. High cost of installation. Vandalism of telephone equipment.

They also offer ideal site for fish breeding because of calm water and availability of the planktons. Ii - When warm currents meet cold currents the temperature of water is regulated. -. This condition is ideal for the survival of fish. -. Convergence of these currents improve circulation of oxygen and dispersal of nutrients for the fish c i Provision of the necessary infrastructure such as transport routes to enableexploitation of fishing grounds located in remote areas. This will reduce over exploitation on a few accessible fishing grounds like L. Victoria. Fishing FarmingThe development of fish farms complements the fish being caught from natural watersRestocking of over fished grounds. Over fished waters are restocked using finger lings from hatcheries or obtaining them from the overpopulated fishing grounds. International agreements on territorial waters. Countries have full sovereignty over territorial water extending for 19 km from the coast. A further 19 km zone in which the coastal state can take action against those whobreak the law. 6. I Smoking.- Sun drying. -. Salting- Use of refrigerator. Ii - The fishermen are required to have a licence from the governmentThis prohibits illegal fishing, over fishing and indiscriminate fishing. -. Inadequate capital. Most of the fishermen use traditional methods of fishing which greatly reduces their catch. They lack adequate funds to enable them purchase modern fishing gear and refrigeration equipment.

- Inadequate capital. Most of the fishermen use traditional methods of fishing which greatly reduces their catch. They lack adequate funds to enable them purchase modern fishing gear and refrigeration equipment. --Introduction of new species. The introduction of new fish species in the lake has affected the breeding of indigenous fish. For example Nile Perch was introduced in the lake in 1960s, it now accounts for more than 80 of the fish harvests, after having caused the disappearance of more than 200 endemic fish species and yet it s not a popular species. -. Presence of weeds. Fishing in lake Victoria is greatly hampered by the grown of water hyacinth along the shores of the lake. The weed chokes the fishing boats, hence the infested areas are avoided by fishermen, yet they contain a lot of fish. -AccidentsAccidents affecting fishermen are common on L. Victoria. Have canoes and boats capsize in the lake due to the strong winds and storms prevailing in the areas. The fishermen loose their fishing gear and equipment, as some of them drone. -. Regional Conflicts. There has been boundary conflict between Kenya and Uganda over Migingo Island on L. Victoria. This has caused the fishermen to have fear since most of them are molested or attacked by Uganda Security groups. 7. -. The continental shelf is narrow- Poor transport connection to the fisheries- Local fishermen do not have adequate capital- The coastline is fairly straight- the water is too warm for fish breeding lack of upwelling of water- There is low demand for fish- Fishermen lack modern equipment preservation facilities storage facilities- Inadequate skills inadequate research technology- Competition from developed countries8.

This crowns and closeness of the trees form a dense shade for the lower layer which makes arvesting cumbersome. Most trees are tall, and have huge trunks. This makes them cumbersome to be harvested and most of them are heavy to be transported. High amount of rainfall. This forest lies within the equatorial climatic region where high amount of rainfall isreceived throughout the year. This means that harvesting of trees can not take place throughout the year because of the very dump condition in the forest and general disturbance caused too much rains. Tree species are not found in pure standsRainforest do not have pure stand and this become a problem if one need to harvest only one species meaning moving from one part of the forest to another as one harvest. Majority of the species are hardwood.-These species are hard to be cut and also heavy to be transported.

It requires extensive land that is only available in those areas. -. It reduces the conflict of resettling people. B - Polluted water cause death of aquatic animals. -. High concentration of organic and inorganic nutrients in water causes electrificationin lakes. -. Water pollution causes diseases to animalsc i - When a river contains excess waters which it cannot hold within its channel. -. When the level of the sea or lake rises due to increased rainfall. -. Exceptional heavy rainfall like El nino results in excess water on land. -. When a dam built across a valley breaks, the water in the reservoir floods lower landdown stream. -. When massive earthquake occurs on the seabed causes tsunami which causesflooding in coastal areas. C ii - Construction of dykes, dams and levees. These can be constructed across rivers tocontrol the speed of water amount of water flowing downstream. -. Reforestation on slopes and river banks reduces surface run off and erosion increasesthe rate of water infiltration in the ground. -. Improving and diverting river channels. -. Shallow rivers can be dredged to increase their depth. Rivers with meanders ca bestraightened to enable water flow swiftly. Tributaries can be drenched to reduce thevolume of water getting into the main river. D - To sustain human life. -. To protect endangered species. -. For sustainable utilization of resources. -. For aesthetic value.
