GEOGRAPHY ANSWERS FOR THE TOPIC TRANSPORT AND COMMUNICATION
1. a i) – Demand
– Availability of infrastructure
– Topography/ terrain
– Capital availability
– Political factor
– Historical factors
– Climate
ii) – Difficult terrain – This makes it difficult to develop transport and communication
i.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 it
uneconomical to construct the transport and communication facilities
– Non – navigable rivers
