Which of the following landforms is created by wind abrasion cutting into steep-sided, narrow ridges and furrows aligned parallel to the prevailing wind direction in arid regions?

Cevabı ve açıklamayı göster

Cevap: Yardang

Cevap

Yardang is created by wind abrasion eroding parallel bands of hard and soft rock aligned in the direction of the prevailing wind.
A Yardang is formed when wind abrasion undercuts and sculpts rocks into long, narrow, steep-sided ridges separated by furrows, aligning parallel to the direction of the prevailing wind in desert landscapes.

Adım Adım Çözüm

1
Analyze the process and geological arrangement described in the stem.
The process is wind abrasion operating parallel to prevailing winds in arid conditions.
Differentiation between desert landforms relies on rock orientation (vertical vs horizontal) and process direction.
2
Distinguish between Yardang and Zeugen based on rock strata alignment.
Yardangs develop where vertical bands of hard and soft rocks lie parallel to wind direction, creating narrow ridges and furrows.
Zeugen require horizontal strata where wind abrades jointed hard rocks into tabular blocks.
3
Identify and reject distractors from non-aeolian domains.
Oxbow lakes originate from fluvial action and moraines from glacial deposition.
Landform classification requires isolating the active agent of erosion or deposition.

In an agricultural district in West Africa, prolonged seasonal droughts and declining crop yields have prompted a massive out-migration of young working-age adults to coastal industrial cities. Which of the following best evaluates the primary demographic and economic consequence of this migration stream on the rural source community?

Cevabı ve açıklamayı göster

Cevap: A sharp increase in the rural economic dependency ratio as the proportion of non-working age inhabitants rises relative to the active labor force.

Cevap

The primary consequence on the rural source area is a sharp increase in the economic dependency ratio as the proportion of non-working age inhabitants (children and the elderly) increases relative to the remaining productive workforce.
The selective out-migration of young, economically active adults directly reduces the denominator of the working-age population. Consequently, the relative proportion of non-working children and elderly relatives increases, elevating the economic dependency ratio and causing labor shortages in rural agriculture.

Adım Adım Çözüm

1
Analyze the migration stream composition
Selective out-migration primarily removes young adults (economically active age cohort, typically 15–59 years) from the rural origin.
Rural-urban drift in developing regions is demographically selective, attracting young workers seeking urban employment.
2
Evaluate demographic ratio shifts
The proportion of dependents (individuals aged under 15 and over 60) relative to the active labor force increases.
The dependency ratio formula is defined as \(\frac{\text{Pop}_{<15} + \text{Pop}_{\ge 65}}{\text{Pop}_{15-64}} \times 100\). A shrinking denominator elevates the overall ratio.
3
Determine economic impacts on the source area
Rural agricultural productivity declines due to labor shortages, while social burden on remaining workers rises.
Fewer working hands must support a higher relative number of dependents, leading to economic strain on the rural origin.

Arrange the following stages of alpine glacial landform evolution in sequential order from the initial pre-glacial hollow to the final alpine peak landform.

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct sequence begins with the formation of a nivation hollow, followed by its enlargement into a bowl-shaped cirque, the sharpening of dividing rock walls into an arête by adjacent cirques, and culminates in the formation of a pyramidal peak by three or more converging cirques.
Alpine glacial landscapes evolve systematically from small localized hollows to complex high-relief landforms. Snow accumulates in hillside depressions where freeze-thaw weathering creates a nivation hollow. As ice thickens and begins rotational movement, plucking and abrasion transform the hollow into a deep, bowl-shaped cirque. When neighboring cirques erode headward towards each other, their dividing rock wall is carved into a narrow, sharp-edged arête. Finally, when three or more cirques erode into the same mountain block from different directions, their intersecting headwalls isolate a steep, horn-like pyramidal peak.

Adım Adım Çözüm

1
Identify the initial weathering and accumulation process.
Freeze-thaw action and snow gathering produce a nivation hollow in a shallow mountain slope depression.
Glacial landform development begins with pre-glacial nivation in minor depressions.
2
Identify the primary landform created by active glacial scouring.
Rotational movement of glacier ice scours out an armchair-shaped cirque with a steep headwall and basin floor.
Plucking and abrasion deepen and expand the nivation hollow into a true cirque.
3
Determine the feature created between two adjacent expanding cirques.
Headward erosion from two opposite or neighboring cirques leaves a narrow, steep ridge known as an arête.
An arête requires pre-existing cirques eroding toward one another.
4
Determine the peak landform formed when multiple cirques meet.
When three or more cirques erode headward around a single mountain summit, they leave a sharp pyramidal peak.
This represents the apex of mountain glacial erosion.

Unlike the Nile and Niger rivers which experience pronounced seasonal fluctuations in volume, the Congo River maintains a remarkably consistent discharge throughout the year. Which of the following geographic factors is primarily responsible for this steady flow regime?

Cevabı ve açıklamayı göster

Cevap: The river basin straddles the Equator, allowing northern and southern tributaries to experience alternating wet seasons that balance total flow.

Cevap

The steady flow regime of the Congo River is primarily due to its drainage basin straddling the Equator, which results in complementary seasonal rainfall peaks from northern and southern tributaries.
The Congo River basin is uniquely positioned across the Equator. Because rainfall in tropical Africa follows the seasonal migration of the overhead sun, the northern tributaries reach peak volume when the southern tributaries are low, and vice versa. This complementary hydrological contribution ensures that the main stem of the Congo River receives a constant supply of water year-round.

Adım Adım Çözüm

1
Analyze the geographical location and extent of the Congo River drainage basin.
The basin lies symmetrically across the Equator in Central Africa, covering regions in both Northern and Southern Hemispheres.
Understanding equatorial symmetry is essential for evaluating seasonal precipitation patterns.
2
Examine the seasonal distribution of rainfall in equatorial Africa.
When the Northern Hemisphere tributaries experience their dry season, the Southern Hemisphere tributaries experience maximum rainfall, and vice versa.
The movement of the Intertropical Convergence Zone (ITCZ) causes alternating rainy seasons on either side of the Equator.
3
Determine the effect of this rainfall pattern on river discharge.
The high stage of tributaries on one side of the Equator balances the low stage of tributaries on the other side, maintaining a stable volume at the main outlet throughout the year.
Complementary tributary inflows compensate for individual seasonal dips.

In the extreme northern savanna belt of Nigeria bordering the Niger Republic, agricultural productivity is severely threatened by wind erosion and topsoil desiccation during the long dry season. Which major soil group characterizes this semi-arid zone, and which soil conservation strategy is specifically designed to combat this wind-driven soil loss?

Cevabı ve açıklamayı göster

Cevap: Regosols and Brown soils; establishment of shelterbelts and tree windbreaks perpendicular to prevailing winds

Cevap

Regosols and Brown soils paired with the establishment of shelterbelts and tree windbreaks perpendicular to prevailing winds
In Nigeria, soil distribution closely follows latitudinal climatic zones. The extreme northern fringes (Sudan and Sahel savanna belts) are dominated by weakly developed, sandy Regosols and Brown soils. Because these loose soils are susceptible to severe wind erosion during the dry Harmattan season, establishing shelterbelts—lines of deep-rooted trees planted perpendicular to the prevailing winds—serves as the primary biological conservation technique to break wind force and stabilize topsoil.

Adım Adım Çözüm

1
Identify the soil zone based on geographical position and climatic conditions.
The extreme northern boundary of Nigeria (e.g., northern Sokoto, Katsina, Jigawa, Yobe, and Borno states) lies in the semi-arid zone where weakly developed sandy soils (Regosols and Brown soils) predominate.
Nigerian soil distribution mirrors latitudinal climatic and vegetation belts from south to north.
2
Determine the dominant soil degradation process in this environment.
Desiccation caused by high temperatures and strong dry Harmattan winds blowing from the Sahara Desert leads to severe wind erosion.
Sparse vegetation cover in semi-arid zones leaves topsoil exposed to wind action during dry periods.
3
Select the appropriate targeted soil conservation technique.
Afforestation through shelterbelts (strips of trees planted across the path of prevailing winds) reduces wind speed, retains moisture, and traps shifting sand.
Water-focused measures (such as terracing or contouring) target water runoff on slopes, whereas shelterbelts specifically target wind-driven erosion on flat arid plains.

When preparing a company's Statement of Profit or Loss, financial accountants present line items and key profit figures in a standardized vertical structure. How should the following financial deductions and intermediate totals be ordered from the top of the statement down to the final profit for the year?

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct presentation sequence in a company Statement of Profit or Loss is: (1) Deducting Cost of Sales from Revenue to compute Gross Profit, (2) Subtracting operating expenses from Gross Profit to obtain Profit from Operations, (3) Deducting finance costs (such as debenture interest) to determine Profit Before Tax, and (4) Subtracting corporate income tax expense from Profit Before Tax to arrive at Profit After Tax.
The standard vertical format of a company's Statement of Profit or Loss follows a logical sequence: Revenue minus Cost of Sales yields Gross Profit; deducting operating expenses gives Profit from Operations; deducting finance costs like debenture interest yields Profit Before Tax; and subtracting income tax expense gives Profit After Tax.

Adım Adım Çözüm

1
Determine the initial gross profit section calculation.
Cost of Sales is subtracted from Revenue to determine Gross Profit.
Standard accounting rules require reporting trading gross profitability prior to administrative and distribution overheads.
2
Calculate the operating profit figure.
Operating expenses are deducted from Gross Profit to arrive at Profit from Operations.
Administrative, selling, and distribution expenses reflect core operational performance.
3

3. Provision for doubtful debts is to be adjusted to 5% of Trade Receivables.

What is the net profit before taxation to be reported in the Statement of Profit or Loss?

Cevabı ve açıklamayı göster

Cevap: ₦354,000

Cevap

The net profit before taxation to be reported in the Statement of Profit or Loss is ₦354,000.
The correct profit calculation accounts for prepaid rent by deducting ₦10,000 from rent paid (giving ₦50,000) and adding accrued salaries of ₦10,000 to salaries paid (giving ₦100,000), yielding ₦150,000 in total operating expenses. The required provision for doubtful debts is 5% of ₦160,000 = ₦8,000. Since the existing provision is ₦12,000, there is a reduction of ₦4,000, which is added as income to Gross Profit. Thus, Net Profit = ₦500,000 + ₦4,000 - ₦150,000 = ₦354,000.

Adım Adım Çözüm

1
Calculate the adjusted Rent expense for the current period.
Rent expense = ₦60,000 - ₦10,000 (prepaid) = ₦50,000.
Prepaid expenses relate to future periods and must be deducted from cash paid.
2
Calculate the adjusted Salaries expense for the current period.
Salaries expense = ₦90,000 + ₦10,000 (accrued) = ₦100,000.
Accrued expenses represent incurred costs not yet paid and must be added.
3
Determine total operating expenses.
Total operating expenses = ₦50,000 + ₦100,000 = ₦150,000.
Sum of adjusted rent and salaries expenses.
4
Calculate the required provision for doubtful debts and compare it with the existing provision.
New provision = 5% of ₦160,000 = ₦8,000. Existing provision = ₦12,000. Reduction in provision = ₦12,000 - ₦8,000 = ₦4,000 (Income).
A decrease in provision for doubtful debts is credited to the Statement of Profit or Loss as income.
5
Compute Net Profit before taxation.
Net profit = Gross Profit (₦500,000) + Provision Reduction (₦4,000) - Operating Expenses (₦150,000) = ₦354,000.
Net profit is gross profit plus other income minus operating expenses.

Cevabı ve açıklamayı göster

Cevap: ₦40,000

Cevap

The net profit for the year ended 31 December 2025 is ₦40,000.
The correct option is ₦40,000. Opening Capital is computed as total opening assets (₦300,000) minus opening liabilities (₦50,000) = ₦250,000. Closing Capital is computed as total closing assets (₦330,000) minus total closing liabilities including accrued electricity (₦50,000) = ₦280,000. Total drawings equal ₦40,000 (₦25,000 cash + ₦15,000 goods). Applying the formula: Net Profit = Closing Capital (₦280,000) + Drawings (₦40,000) - Capital Introduced (₦30,000) - Opening Capital (₦250,000) yields ₦40,000.

Adım Adım Çözüm

1
Calculate Opening Capital as of 1 January 2025
Total Opening Assets = ₦180,000 + ₦60,000 + ₦40,000 + ₦20,000 = ₦300,000. Opening Liabilities = ₦50,000. Opening Capital = ₦300,000 - ₦50,000 = ₦250,000.
Opening capital represents net assets at the start of the period.
2
Calculate Closing Capital as of 31 December 2025
Total Closing Assets = ₦160,000 + ₦85,000 + ₦55,000 + ₦30,000 = ₦330,000. Closing Liabilities = ₦40,000 + ₦10,000 = ₦50,000. Closing Capital = ₦330,000 - ₦50,000 = ₦280,000.
Accrued expenses are liabilities and must be added to trade creditors when computing total closing liabilities.
3
Calculate Total Drawings
Total Drawings = Cash Drawings (₦25,000) + Goods Drawings (₦15,000) = ₦40,000.
Both cash and goods taken by the owner for personal use reduce business equity and must be added back to compute net profit.
4
Apply the Statement of Affairs Profit Formula
Net Profit = Closing Capital (₦280,000) + Drawings (₦40,000) - Capital Introduced (₦30,000) - Opening Capital (₦250,000) = ₦40,000.

What is the balance of the Retained Earnings (Profit and Loss Account) as at 31st December 2025?

Cevabı ve açıklamayı göster

Cevap: 50000

Cevap

The balance of Retained Earnings as at 31st December 2025 is ₦50,000.
Under the company accounting framework, Net Assets equals total Shareholders' Equity. Total Assets of ₦800,000 less Current Liabilities of ₦70,000 and Non-Current Liabilities of ₦100,000 leaves Net Assets of ₦630,000. Subtracting the known equity items (Share Capital ₦500,000 + Share Premium ₦50,000 + General Reserve ₦30,000 = ₦580,000) yields the Retained Earnings balance of ₦50,000.

Adım Adım Çözüm

1
Calculate Total Assets
₦800,000
Total Assets is the sum of Non-Current Assets (₦620,000) and Current Assets (₦180,000).
2
Calculate Net Assets (Capital Employed by Equity)
₦630,000
Net Assets is determined by deducting Current Liabilities (₦70,000) and Non-Current Liabilities (₦100,000) from Total Assets (₦800,000).
3
Sum known Shareholders' Equity components
₦580,000
Add Share Capital (₦500,000), Share Premium (₦50,000), and General Reserve (₦30,000).
4
Deduct known equity components from Net Assets to solve for Retained Earnings
₦50,000
Retained Earnings = Net Assets (₦630,000) - Known Equity (₦580,000) = ₦50,000.

Arrange the following key geographical features and locations along the course of the River Niger in sequential order, starting from its source region in West Africa and moving downstream towards its lower course in Nigeria.

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct sequential order from upstream to downstream is Fouta Djallon Highlands, followed by Macina Inland Delta, Kainji Dam Reservoir, and Lokoja Confluence.
The correct order traces the natural downstream flow of the River Niger: 1. Fouta Djallon Highlands (source in Guinea) -> 2. Macina Inland Delta (Mali floodplains) -> 3. Kainji Dam Reservoir (middle course impoundment in Nigeria) -> 4. Lokoja Confluence (confluence with the Benue River in central Nigeria).

Adım Adım Çözüm

1
Identify the headwaters/source region of the River Niger.
The River Niger originates in the high-altitude Fouta Djallon Highlands near the border of Sierra Leone in Guinea.
A river course always begins at its elevated source region.
2
Trace the river flow into Mali.
As the river flows northeast into Mali, the low slope causes it to spread out into the Macina Inland Delta.
The inland delta is an upper-middle course wetland feature situated prior to the northern desert bend.
3
Trace the river entering western Nigeria.
After looping south through Niger Republic into Nigeria, the river is impounded to form the Kainji Dam Reservoir.
Kainji Lake represents a major middle-course feature in western Nigeria.
4
Locate the major tributary junction in central Nigeria.
Further downstream at Lokoja, the River Niger merges with the Benue River before flowing towards the Gulf of Guinea.
The Lokoja confluence occurs downstream of Kainji in the lower course of the river system.

What is the net profit for the year in Naira (N\text{N})?

Cevabı ve açıklamayı göster

Cevap: 56000

Cevap

The net profit for the year is N56,000.
To determine the net profit, add revenues (Gross profit of N120,000 + Discount received of N4,500 = N124,500) and subtract all adjusted operating expenses (Rent of N15,000 + Salaries of N36,000 + General expenses of N15,000 + Doubtful debts provision of N2,500 = N68,500). Net profit equals N124,500 - N68,500 = N56,000.

Adım Adım Çözüm

1
Calculate Total Income
Total Income = N124,500
Discount received is revenue income and must be added to gross profit in the Profit and Loss Account.
2
Adjust Rent for prepayment
Adjusted Rent = N15,000
Prepayments relate to the next accounting period and must be deducted from rent paid during the current period.
3
Adjust Salaries and Wages for accrual
Adjusted Salaries = N36,000
Accrued expenses represent benefits consumed but not yet paid, so they must be added to wages paid under the matching concept.
4
Compute Provision for Doubtful Debts
Provision = N2,500
Creating a 5% provision on trade debtors of N50,000 creates an operating expense of 0.05 * 50,000 = N2,500.
5
Sum total adjusted operating expenses
Total Expenses = N68,500
Total operating expenses include rent (N15,000), salaries (N36,000), general expenses (N15,000), and provision for doubtful debts (N2,500).
6
Deduct total expenses from total income to find Net Profit
Net Profit = N56,000
Net Profit is computed as Total Income (N124,500) minus Total Operating Expenses (N68,500).

Cevap: Iroko

Cevap

Iroko is an indigenous tropical hardwood species from African equatorial rainforests.
Iroko is a broad-leaved tree species indigenous to the tropical rainforest belt of West and Central Africa, producing dense, high-value commercial hardwood used extensively for furniture and construction.

Adım Adım Çözüm

1
Identify the natural vegetation zone and characteristic timber types of West and Central Africa.
The region is dominated by tropical rainforests comprising broad-leaved trees.
Equatorial climate conditions support broad-leaved hardwood species rather than coniferous softwoods.
2
Classify the given options into hardwoods vs. softwoods.
Iroko (along with Mahogany, Sapele, and Obeche) is a tropical hardwood. Pines, spruces, and firs are temperate softwoods.
Distinguishing tropical broad-leaved hardwoods from temperate coniferous softwoods identifies the native commercial timber.
