Very Accurate.


==============================

(1a)
(i) Availability of labour
(ii) Availability of capital
(iii) Nearness to source of power
(iv) Adequate transport network
(v) Nearness to market

====================
(2ai)
total population = 3.2+5.4+7.4+6.5+4.2
= 26.7million
(2aii)
Total land area = (40,000+98,000+35,000+120,000+36,000)km^2
= 479,000km^2
(2aiii)
Population density of country B= Total population of B/Land area of B
= 26,000,000/ 479,000
= 557.41 person/sqkm

(2b)
(i)Agriculture
Areas with well developed farming of crops or animals are often densely populated.
(ii) Secondary industry
Those areas in which manufacturing has developed tend to be densely populated. It is worth noting that even in old industrial areas in which manufacturing has declined or even closed, population densities may remain high.
(iii) Accessibility
Areas with well developed transport infrastructure and links through road, rail, shipping, canals and air are likely to be more densely populated than areas which are poorly connected
(iv)Conflict
Wars and conflicts can lead to significant movements of population and a simultaneous decrease in density in some areas while others may increase.

(2c)
(i)Healthcare/access to health care/medical technology/ability to fight or prevent disease
(ii)Availability of birth control/availability of family planning education/use of birth control
(iii)Culture-social norms, values, and traditions (the use of contraception, the age at which marriage is socially acceptable, religious beliefs on family planning, gender equality, etc.)

(II)it makes goods available where they are scare
(III)Road facilitate the movement of people within a short distance
(IV)it feeds water ,rail and air transportation
(V)It is the most common means of transportation

(II)it leads to increased agricultural, mineral and industrial production
(III)It aids the movement of people or labour and capital
(IV)it gives rise to employment opportunities
(V)It links areas of production with areas of consumption
in a country


(4b)

(i)Climatic conditions such as temperature and rainfall significantly influence the groundnut production. Warm and moist conditions are very favorable than cool and wet climate, which results in slow germination and seedling emergence, increasing the risk of seed rot and seedling diseases.

(ii) Temperature is a major environmental factor that determines the rate of crop development. Temperatures above 35°C inhibit the growth of groundnut. Optimum mean daily temperature to grow is 30°C and growth ceases at 15°C. For rapid emergence, soil temperature above 21°C is needed. The optimum temperature for the most rapid germination and seedling development is about 30°C.

(iii). A minimum 100 - day optimum temperature growing season is necessary for successful groundnut crop production. Adequate and well distributed rainfall during the growing season, especially during flowering, pegging and pod formation stages, is essential for maximum yield and quality of groundnut. Groundnut is grown in areas receiving 600 to 1500 mm of rainfall. However, the crop can be grown successfully with a rainfall of 1250 mm.

(4c)

-Nigeria is one of the countries of the world with a variety of oil seeds notably groundnut, oil palm, soybean and cotton seeds. Vegetable oils are used principally for food (mostly as shortening, margarines, and salad and cooking oils) and in the manufacture of soap and other products.

-Groundnut is by far the most nutritive oil-seed used in West Africa. The kernels have an average fat and protein content of 75% and an energy value of 360 kcal/100g, compared to 60% and 430 kcal/100 g for soybeans.

-In Nigeria, Groundnut provides high quality cooking oil and is an important source of protein for both human and animal diet and also provides much needed foreign exchange by exporting kernels and cake.

- As population continues to grow the demand for edible oil in many developing countries such as Nigeria will also continue to grow.

-Groundnut will continue to be important in satisfying this growing demand because it is adaptable to a wide range of environments from sandy soils of the Sahel to favorable irrigated areas

B. Physical Factors
1. Relief and landforms
Lowland plains, flat river valleys and deltas and volcanic areas with fertile soil tend to have high population densities. Mountainous areas with steep slopes and poor quality soil tend to have low population densities.

2. Weather and climate
Temperate areas which experience few extremes of weather and climate tend to be more attracted than areas which experience extremes. Areas which are very dry, very cold or very wet tend to have sparse populations whereas areas which have a moderate climate with evenly distributed rainfall or with monsoon type climates have denser populations.

3. Soil type and quality
Areas which have rich, fertile soils allowing successful agriculture tend to have higher population densities than areas which have poor quality soils have sparse populations. Good quality soils may be found in low lying areas such as river flood plains and deltas where silt is deposited; in volcanic areas; in areas which have a high natural humus content. Poor quality soils may be found in areas with steep slopes; areas with very high rainfall throughout the year which tends to leach nutrients fro the soil; cold areas of permafrost; areas experiencing soil degradation through human management e.g. over-grazing/deforestation.

4. Water supply
Water supply is essential for human survival and development and because of this areas which have sufficient water (but not too much) tend to have denser populations than areas which are dry or suffer from regular drought or areas which have excessive rainfall or which may be prone to flooding.

5. Vegetation
Some types of vegetation make the development of settlement more likely, e.g. grasslands. Areas with particularly dense rainforest, coniferous forests or those with little vegetation tend to have sparse populations.

6. Raw materials/natural resources
Areas with a wealth of natural resources such as oil, coal or minerals may have higher population densities than areas which do not. It is important to remember though that natural resources may be found in otherwise harsh environments and that they may be traded and exported/used in areas other than where they are extracted.

7. Natural threats
These may affect population density as people may try to avoid areas where pests, threatening animals and diseases are particular risks.

Human Factors
1) Agriculture
Areas with well developed farming of crops or animals are often densely populated.

2) Secondary industry
Those areas in which manufacturing has developed tend to be densely populated. It is worth noting that even in old industrial areas in which manufacturing has declined or even closed, population densities may remain high.

3) Accessibility
Areas with well developed transport infrastructure and links through road, rail, shipping, canals and air are likely to be more densely populated than areas which are poorly connected

4) Political decisions
Government policy can have a significant impact upon population densities. This can occur if governments decide to open up previously underdeveloped areas (e.g. Brasilia and the development of the Trans-Amazonian Highway in Brazil; the movement of Han Chinese to Tibet; the development of Abuja as a new capital city in Nigeria). If governments decide not to invest in an area it may also lose large numbers of people leading to reduced population density.

5) Conflict
Wars and conflicts can lead to significant movements of population and a simultaneous decrease in density in some areas while others may increase.
