Match each slope measurement scenario on the left with its corresponding calculated gradient on the right.

Soldaki öğeye tıklayın, sonra eşleşen sağdaki öğeye tıklayın

Cevabı ve açıklamayı göster

Cevap

Vertical Interval = 80 m, HE = 1.6 km matches 1 in 20 (5%); VI = 150 m, HE = 600 m matches 1 in 4 (25%); VI = 50 m, HE = 2.5 km matches 1 in 50 (2%); VI = 200 m, HE = 1 km matches 1 in 5 (20%).

Each scenario is correctly matched by converting all horizontal distances into meters and calculating the simplified ratio VI / HE, expressed as both a ratio (1 in N) and a percentage.

Adım Adım Çözüm

Convert all Horizontal Equivalent (HE) distances given in kilometers to meters so that units match the Vertical Interval (VI).

1.6\text{ km} = 1,600\text{ m}

2.5\text{ km} = 2,500\text{ m}

, and

1\text{ km} = 1,000\text{ m}

Both Vertical Interval and Horizontal Equivalent must be in the same units of measurement before calculating the ratio.

Apply the gradient formula

\text{Gradient} = \frac{\text{Vertical Interval (VI)}}{\text{Horizontal Equivalent (HE)}}

to each scenario.

Scenario 1:

\frac{80}{1600} = \frac{1}{20}

; Scenario 2:

\frac{150}{600} = \frac{1}{4}

; Scenario 3:

\frac{50}{2500} = \frac{1}{50}

; Scenario 4:

\frac{200}{1000} = \frac{1}{5}

Dividing vertical rise by horizontal distance yields the simplified slope fraction.

Express each simplified fraction in standard ratio (

1 \text{ in } N

) and percentage formats.

\frac{1}{20} = 1\text{ in } 20\ (5\%)

\frac{1}{4} = 1\text{ in } 4\ (25\%)

\frac{1}{50} = 1\text{ in } 50\ (2\%)

\frac{1}{5} = 1\text{ in } 5\ (20\%)

This allows matching the calculated values directly to the corresponding choices on the right.

Calabar lies on the Calabar River in southeastern Nigeria and primarily handles regional forest products such as timber, as well as agricultural palm produce.

The surrounding vegetation belt of dense rainforest historically and functionally supports timber and oil palm exports.

Identify the operational purpose of Tin Can Island Port

Tin Can Island was established in the late 1970s in the Lagos lagoon complex to expand container cargo capacity and ease extreme vessel congestion at Apapa Port.

Lagos is the premier commercial portal of Nigeria, handling the bulk of nationwide industrial containerized cargo.

Cevap

Ahaggar Massif pairs with the elevated Precambrian crystalline highland in the Sahara; Congo Basin pairs with the vast interior cratonic downwarp; East African Rift Valley pairs with the extension-formed linear trough bounded by normal fault scarps; Cape Fold Belt pairs with the ancient Palaeozoic fold mountain belt.

Each feature correctly matches its structural type: the Ahaggar Massif is an uplifted crystalline basement block in the Sahara; the Congo Basin is a classic continental downwarp (basin structure); the East African Rift Valley is an extensional fault trough; and the Cape Fold Belt is an ancient Palaeozoic fold mountain range.

Adım Adım Çözüm

Analyze the geological classification of Saharan high massifs such as the Ahaggar.

Identify that the Ahaggar Massif consists of exposed Precambrian basement rocks uplifted into a high plateau complex.

Swell uplift in northern and central Saharan shield regions formed high interior basement massifs.

Examine the formation mechanism of the interior African drainage depressions like the Congo Basin.

Identify the Congo Basin as an epeirogenic downwarp (basin-and-swell structure).

Continental basin-and-swell tectonics in Africa created broad central depressions surrounded by rimming highlands.

Identify the structural process producing the East African Rift System.

Match it to extensional faulting and graben formation bounded by normal fault scarps.

Tensional forces pull the crust apart, causing central blocks to sink relative to adjacent horsts.

Classify the fold mountain structures of Southern Africa.

Match the Cape Fold Belt to Palaeozoic crustal compression and folding.

Unlike the Cenozoic young fold mountains of the Atlas, the Cape ranges represent older Palaeozoic orogenic activity.

Cevap

Commercial Plantation Agriculture matches large-scale export crop cultivation in tropical forest belts; Rotational Bush Fallowing matches cultivating fields with fallow periods around fixed settlements; Mixed Farming matches integrating crop growing and livestock rearing on one farm; Oasis Farming matches intensive cultivation around desert water sources.

Each agricultural system is uniquely defined by its land usage: commercial plantations specialize in cash crop estates, bush fallowing utilizes land rotation around permanent villages, mixed farming integrates animals with crop production, and oasis agriculture utilizes localized desert water points.

Adım Adım Çözüm

Analyze each agricultural system name to identify its core operational method.

Plantation agriculture implies large cash crop estates; bush fallowing implies land rotation around fixed homes; mixed farming combines crops and animals; oasis farming uses desert groundwater.

Matching requires pairing the primary farming practice with its distinct environmental setting and land management strategy.

Pair each farming system with its corresponding operational description.

Commercial Plantation Agriculture pairs with export tree crop cultivation in forest zones; Rotational Bush Fallowing pairs with field rotation around fixed settlements; Mixed Farming pairs with joint crop-livestock production; Oasis Farming pairs with desert spring cultivation.

This establishes accurate pairings based on African agricultural geography.
