here are the answers to Questions 3, 4, and 5 from Section C. SECTION C: HUMAN GEOGRAPHY Question 3 a) (i) State THREE problems faced by natural vegetation across the world today. • Deforestation: Widespread clearing of forests for agriculture, logging, and urbanization. • Climate Change: Altered temperature and rainfall patterns, leading to habitat shifts and increased frequency of extreme weather events like droughts and wildfires. • Pollution: Contamination of soil and water by industrial waste, agricultural chemicals, and plastic, harming plant health and growth. a) (ii) Outline THREE ways by which plants in hot deserts adapt to the climatic characteristics of the area. • Succulence: Many desert plants, like cacti, store water in their fleshy stems or leaves to survive long dry periods. • Deep root systems: Some plants develop extensive root systems to reach groundwater far below the surface. • Small or spiny leaves: Leaves are often reduced in size or modified into spines to minimize water loss through transpiration. b) Write brief notes on any TWO of the following: (i) Orographic or relief rainfall (formation) Orographic rainfall occurs when moist air is forced to rise over a mountain barrier. As the air ascends, it cools, leading to condensation and the formation of clouds. Precipitation then falls on the windward side of the mountain, while the leeward side experiences a rain shadow effect. (iii) Equatorial climate (characteristics and location) The equatorial climate is found approximately between 0^ and 10^ north and south of the equator. It is characterized by consistently high temperatures and heavy rainfall throughout the year, often with two peak rainy seasons. Humidity is high, and daily convectional rainfall is common, supporting dense tropical rainforests. c) "Volcanic areas are very risky zones yet people still choose to live there." Suggest FOUR reasons for this. • Fertile soil: Volcanic ash and weathered lava create extremely fertile soils, ideal for agriculture and high crop yields. • Geothermal energy: Volcanic regions often provide access to geothermal energy, a renewable and clean source of power. • Mineral deposits: Volcanic activity can lead to the formation of valuable mineral deposits, attracting mining and related industries. • Tourism: The dramatic landscapes, hot springs, and unique geological features of volcanic areas attract tourists, creating employment and economic opportunities. Question 4 a) On the world map provided, insert and name: Note: An outline map of the world was not provided in the image, so I will list examples for each category. (i) TWO important fishing grounds in the Northern Hemisphere, Grand Banks* (off Newfoundland, Canada) North Sea* (between UK and Scandinavia) (ii) TWO areas of high concentration of industries, Ruhr Valley* (Germany) Northeast USA* (e.g., Great Lakes region) (iii) TWO areas of low population density, Sahara Desert* (North Africa) Siberia* (Russia) (iv) TWO shipping routes. Suez Canal* (Egypt) Panama Canal* (Panama) b) Using specific examples, distinguish between: (i) Push and pull factors of migration, Push factors are negative conditions that compel people to leave their homes, such as war (e.g., conflict in Syria), poverty, or natural disasters (e.g., drought in the Sahel). Pull factors are attractive conditions that draw people to a new location, such as job opportunities (e.g., in developed countries), better education, or political stability. (ii) Rural and urban settlements, Rural settlements are characterized by low population density, a strong reliance on primary economic activities like agriculture (e.g., a farming village), and a close connection to the natural environment. Urban settlements have high population density, diverse non-agricultural economic activities (e.g., a city with industries and services), and extensive infrastructure. (iii) Primary and Secondary industries. Primary industries involve the extraction or harvesting of raw materials directly from the Earth, such as farming (e.g., growing cocoa), mining (e.g., iron ore extraction), or fishing. Secondary industries process these raw materials into finished or semi-finished goods through manufacturing and construction (e.g., turning cocoa beans into chocolate, building houses). c) (i) Briefly explain why in most Least Industrialised Countries (LICs) more people are engaged in agriculture yet their output is low. In most LICs, a large proportion of the population is engaged in agriculture primarily due to a lack of alternative employment opportunities in other sectors. However, output remains low because farming often relies on traditional methods, lacks modern technology, suffers from insufficient investment, and is vulnerable to climate variability and poor infrastructure. c) (ii) Describe THREE things these nations can do to emerge. • Invest in education and healthcare: Improving human capital through better schooling and health services enhances productivity and innovation. • Diversify the economy: Shifting away from over-reliance on primary products by developing manufacturing and service sectors. • Improve infrastructure: Investing in roads, energy, and communication networks to facilitate trade, investment, and access to markets. Question 5 a) (i) State the economic characteristics of stage 3 of Rostow's model of Economic Growth. Stage 3, known as the "Take-off" stage, is characterized by rapid industrialization, significant investment in manufacturing, and the emergence of leading economic sectors. There is a shift from traditional to modern production methods, increased urbanization, and the development of a more complex economic and social infrastructure. a) (ii) Use a table to classify the following countries into AICS, NICS and LICS: Britain, Nigeria, Cameroon, Japan, Hong Kong, Canada, South Africa, China | AICS (Advanced Industrialized Countries) | NICS (Newly Industrialized Countries) | LICS (Least Industrialized Countries) | | :-------------------------------------- | :------------------------------------ | :------------------------------------ | | Britain | Hong Kong | Nigeria | | Japan | South Africa | Cameroon | | Canada | China | | b) Distinguish between the following: (i) Population density and population distribution, Population density refers to the number of people living per unit area (e.g., 100 people per square kilometer). Population distribution describes the pattern of where people live across a given area, indicating whether they are clustered, dispersed, or linear. (ii) Pastoral farming and Arable farming, Pastoral farming involves the rearing of livestock, such as cattle, sheep, or goats, for products like meat, milk, or wool. Arable farming focuses on the cultivation of crops, such as cereals, vegetables, or fruits. (iii) Light industry and heavy industry. Light industry typically produces small, consumer-oriented goods, often requires less capital investment, and has a lower environmental impact (e.g., textile manufacturing, electronics assembly). Heavy industry produces large, durable goods, requires substantial capital, uses heavy machinery, and often has a significant environmental footprint (e.g., steel production, shipbuilding). c) (i) Briefly explain TWO negative impacts of mining on the environment. • Habitat destruction and deforestation: Mining operations often require clearing large areas of land, leading to the loss of natural habitats and forests. • Water pollution: Mining can release toxic chemicals and heavy metals into rivers and groundwater, contaminating water sources and harming aquatic life. c) (ii) Briefly explain TWO advantages of road transport over rail. • Door-to-door service: Road transport offers unparalleled flexibility, allowing goods and people to be transported directly from their origin to their final destination without transshipment. • Flexibility in routes: Roads provide access to a wider network of locations, including remote areas, and can adapt more easily to changing routes or unexpected diversions compared to fixed rail lines. d) "Tourism increases: health risk, prices of basic needs, crime wave, and prostitution etc." Despite this, countries still promote their tourist industry. Give THREE reasons for this. • Foreign exchange earnings: Tourism is a major source of foreign currency, which countries can use to import goods and services or pay off debts. • Job creation: The tourism sector creates a wide range of employment opportunities, from hotel staff and tour guides to artisans and transport providers. • Infrastructure development: To support tourism, governments often invest in improving infrastructure such as airports, roads, and utilities, which also benefits local residents.
