SECTION A: MAP WORK Please note: The map extract of LIMBE (1:50,000) mentioned in the question was not provided. Therefore, I cannot answer question 1 parts (a), (b), (c), and (d) which require direct reference to the map. I will answer the "OR" option for Question 1. OR 1. a) Outline the orderly procedure used in copying a specific portion of a map: • Secure the map: Place the original map on a flat surface and secure it to prevent movement. • Place tracing paper: Lay a piece of tracing paper over the specific portion of the map to be copied, ensuring it covers the entire area. Secure the tracing paper. • Trace grid lines: Carefully trace the relevant grid lines (eastings and northings) that define the boundaries of the desired area. • Trace features: Systematically trace all the required features within the selected grid squares, such as contour lines, rivers, roads, buildings, and vegetation symbols. • Add marginal information: Include essential marginal information like the map title, scale (both ratio and linear), north arrow, and a key/legend for any symbols used. • Transfer (optional): If a final copy on plain paper is needed, the traced map can be transferred using carbon paper or by shading the back of the tracing paper and re-tracing. b) i) Describe how the six-figure grid reference can be used to identify specified features: A six-figure grid reference provides a precise location within a 100-meter square on a map. • Identify the four-figure grid square: First, locate the main grid square by reading the easting (vertical line) to the left of the feature and the northing (horizontal line) below the feature. This gives the first two digits for easting and the first two for northing. • Estimate the third easting digit: Mentally divide the grid square into ten equal strips from west to east. Estimate how many tenths the feature is to the east from the left-hand easting line. This number (0-9) becomes the third digit of the easting. • Estimate the third northing digit: Similarly, mentally divide the grid square into ten equal strips from south to north. Estimate how many tenths the feature is to the north from the bottom northing line. This number (0-9) becomes the third digit of the northing. • Combine the digits: The six-figure grid reference is then written as three digits for the easting followed by three digits for the northing (e.g., 123456). ii) State the correct order to be followed when calculating the area covered by an aspect on a map: • Identify the feature: Clearly delineate the boundaries of the specific feature whose area is to be calculated (e.g., a forest, a lake). • Count full squares: Count all the complete grid squares that lie entirely within the boundaries of the feature. • Count partial squares: Count the partial grid squares. For accuracy, squares that are more than half covered by the feature are counted as one full square, and those less than half are ignored. Alternatively, estimate the fraction of each partial square and sum them. • Calculate total squares: Sum the number of full squares and the estimated number of partial squares to get the total number of grid squares covered by the feature. • Determine area of one square: Using the map's scale, calculate the actual ground area represented by one grid square (e.g., if the scale is 1:50,000 and grid squares are 2 cm x 2 cm, then 1 square represents 1 km × 1 km = 1 km^2). • Multiply to find total area: Multiply the total number of squares by the area of one square to obtain the total area of the feature on the ground. c) In describing the drainage of a map, outline the various aspects to be considered: • River patterns (drainage patterns): Identify the arrangement of rivers and streams, such as dendritic (tree-like), trellis (rectangular), radial (flowing outwards from a central point), or parallel. • Direction of flow: Determine the direction in which rivers flow by observing the V-shape of contour lines (the V points upstream) or by noting the decreasing height of spot heights along the river course. • Presence of water bodies: Note the existence and distribution of lakes, ponds, swamps, and marshes. • Drainage density: Assess how closely spaced the rivers and streams are, which indicates the permeability of the underlying rock and the amount of surface runoff. • Human modifications: Identify any man-made features related to drainage, such as dams, reservoirs, canals, irrigation channels, or levees. • Waterfalls and rapids: Look for closely spaced contour lines crossing a river, indicating a steep gradient and potential for waterfalls or rapids. d) From your knowledge of Cameroon Geography, outline THREE economic activities, with evidence that can be carried out in a town like Limbe: • Fishing: Limbe is a coastal town with access to the Atlantic Ocean, making fishing a traditional and viable economic activity. Evidence includes fishing boats, fish markets, and processing facilities. • Petroleum refining: Limbe hosts the National Oil Refinery (SONARA), indicating significant activity in the refining of crude oil, which is a major industrial economic activity. • Tourism: With its coastal location, beaches, and attractions like the Limbe Botanical Garden and Limbe Wildlife Centre, tourism is a key economic activity. Evidence includes hotels, resorts, and tourist services. • Port activities/Trade: Limbe has a port, facilitating the import and export of goods, which supports trade and related logistical services. SECTION B: PHYSICAL GEOGRAPHY 2. a) Define any TWO of the following: i) Weathering: The process of in situ breakdown and decomposition of rocks, soils, and minerals through direct contact with the Earth's atmosphere, biota, and waters. It does not involve the removal of the weathered material. ii) Wind abrasion: A type of mechanical erosion where wind-borne particles (like sand and dust) are hurled against rock surfaces, causing them to wear away, polish, or pit. It is particularly effective in arid and semi-arid regions. iii) The long profile of a river: A graphical representation of the gradient of a river from its source (headwaters) to its mouth. It typically shows a concave shape, with a steep gradient in the upper course, a moderate gradient in the middle course, and a gentle gradient in the lower course. b) i) Briefly describe THREE evidences to show that the earth is spherical: • Ships appearing mast first: When a ship approaches from the horizon, its mast or smokestack is visible before its hull. This is because the Earth's curvature hides the lower parts of the ship first. • Lunar eclipse: During a lunar eclipse, the Earth passes between the Sun and the Moon, casting a shadow on the Moon. This shadow is always circular, regardless of the Earth's orientation, which is consistent with a spherical object. • Circumnavigation: It is possible to travel continuously in one direction (east or west) and eventually return to the starting point, as demonstrated by explorers like Ferdinand Magellan. This would not be possible on a flat Earth. • Varying star visibility: Different constellations and stars are visible from different latitudes. For example, the North Star (Polaris) is visible in the Northern Hemisphere but not in the Southern Hemisphere, which is only possible on a curved surface. ii) Briefly define the term Hydrological cycle: The hydrological cycle, also known as the water cycle, is the continuous movement of water on, above, and below the surface of the Earth. It involves processes such as evaporation, condensation, precipitation, runoff, and infiltration, driven primarily by solar energy and gravity. c) Clearly state TWO problems created by each of the following: i) Poor waste management: • Environmental pollution: Leads to contamination of land (soil degradation), water bodies (eutrophication, toxicity), and air (odors, greenhouse gas emissions) from uncollected or improperly disposed waste. • Health hazards: Attracts disease vectors (rats, insects), spreads pathogens, and can cause respiratory problems or other illnesses due to exposure to hazardous materials. ii) Water shortage (scarcity): • Impact on agriculture and food security: Insufficient water for irrigation leads to crop failures, reduced yields, and livestock deaths, threatening food supply and livelihoods. • Health and hygiene issues: Lack of access to clean drinking water and water for sanitation increases the risk of waterborne diseases and compromises public health. iii) Floods: • Loss of life and property damage: Floods can cause drowning, injuries, and extensive destruction of homes, infrastructure (roads, bridges), and agricultural land. • Displacement and economic disruption: Force people to evacuate their homes, disrupt transportation and economic activities, and incur significant costs for recovery and reconstruction. iv) Global warming: • Sea-level rise: Causes thermal expansion of ocean water and melting of glaciers and ice sheets, leading to rising sea levels that threaten coastal communities with inundation and erosion. • Extreme weather events: Increases the frequency and intensity of heatwaves, droughts, heavy rainfall, and tropical storms, leading to greater natural disasters and their associated impacts.
