NECO GEOGRAPHY PART 2 ANSWERS 2020
Optimum population is the number of people that can be supported by available resources in an area, so to achieve highest possible standard of living. It can also be defined when the available resources is equal to the total number of people in an area.
Overpopulation: This is a type of population when the total population is more than the available resources. Overpopulation brings together of people in an area. Overpopulation creates large labour for industries which in turn brings large market. Overpopulation creates pressure on both national resources and social resources as side effects.
Mortality rate: Mortality rate is also known as death rate which can be defined as the rate which people die in a country. It can be expressed in units of death per 1000 individual per year. High mortality rate will lead to low population while low mortality rate will lead to increase in population
Birth rate : Birth rate is also called natality rate which can be defined as the rate at which children are born or given birth to. High birth rate will lead to increase in human population while low birth rate will lead to decrease in human population.
Population density: It refers to the ratio of total population to total land area. It can also be defined as the number of person per unit area of land per kilometres of land.
Mathematically, Population density = total population/total land area
High population density will promote large labour for industries while low population density will provide low labour force for industries. High population density is attributed to over population while low population density is attributed to optimum or under population.

(i) Presence of trees makes it difficult for cultivation of food corps like yam, cassava, potatoes which has occupied the meant for this crop cultivation
(ii) Due to presence of tree in rain forest tract encourages lunbreing which in turn leads to soil erosion make it difficult for development of agricultural because erosion is not friendly to agricultural development

(i) H.E.P. (hydro electric power) hydro electric power is the generation of electricity from water. This is achieved through damming of rivers and the use of river water to turn or drive turbines. Example of H.E.P generation in Nigeria is kainji dam on river Niger Nigeria
(ii) Coal: A coal fired power station or coal plant is a thermal power station which burns coal to generate electricity, Example can be found in kogi and Enugu State with a capacity of 2000MW with 1000mw in each.
(iii) Gas fired power plant: A gas fired plant is a thermal power station which burns natural gas to generate electricity. Example can be located in Calabar with 561MW, Egbema power plant in Imo state with 338MW and Egbin thermal power station location in Egbin with 1320MW
(i) Inadequate capital to construct and maintain power generation: Due to lack of funding by the federal government to power supply generation it affect the static power supply and makes the power supply in Nigeria to be floating
(ii) Low level of technology: Low level of technology affect power generation in Nigeria due to low level and we are still following manual method that makes it difficult to have static power supply especially in Gaseoline and coal power generation
(iii) Seasonal floating of river: the volume of river water increases during drying season and reduces during drying season makes power generation to be floating in Nigeria
