Cevabı ve açıklamayı göster

Cevap

Dendritic pattern pairs with uniform lithology and flat-lying strata; Radial pattern pairs with volcanic domes or central peaks; Trellis pattern pairs with alternating bands of hard and soft folded rocks; Centripetal pattern pairs with inward-sloping interior basins.

Each drainage pattern reflects specific surface geology: dendritic networks form on uniform rocks with equal erosion resistance, radial networks diverge outward from central domes, trellis networks align with alternating bands of folded rocks, and centripetal networks converge inward toward central basins.

Adım Adım Çözüm

1

Identify the characteristic geological setting for a dendritic pattern

Dendritic drainage exhibits random branching on homogeneous rock types.

Equal resistance of underlying rock allows streams to flow in any direction without structural restriction.

2

Identify the structural control of a radial pattern

Radial drainage radiates outward from elevated peaks or domes.

High central relief forces water to flow downhill in all outward directions.

3

Identify the structural control of a trellis pattern

Trellis drainage follows alternating weak and resistant folded strata.

Main streams carve long parallel valleys in soft strata while short tributaries join at right angles across hard ridges.

4

Identify the structural control of a centripetal pattern

Centripetal drainage converges inward into a central depression.

Topography slopes downward toward a common interior low point.

Cevap

Trellis drainage pattern matches with folded strata containing alternating hard and soft rocks; Rectangular pattern matches with faulted and jointed bedrock; Radial pattern matches with outward flow from a central dome or volcano; Dendritic pattern matches with tree-like branching on uniform rock resistance.

Each pattern corresponds directly to its bedrock control: Trellis requires alternating soft/hard folded belts, Rectangular follows structural joints and faults, Radial descends from a central highland dome or cone, and Dendritic branches randomly over uniform lithology.

Adım Adım Çözüm

1

Analyze Trellis Drainage Pattern

Trellis drainage features long main streams parallel to strike valleys with short tributaries entering at right angles, characteristic of folded, tilted strata.

Differential erosion along parallel belts of soft and hard rock forces tributaries into strike valleys.

2

Analyze Rectangular Drainage Pattern

Rectangular drainage is characterized by right-angled bends in main streams and tributaries along lineaments.

Bedrock fractures, joint systems, and faults direct the line of weakest resistance for stream incision.

3

Analyze Radial Drainage Pattern

Radial drainage streams flow in all cardinal directions downward from a central peak.

Topographic highs like domes and volcanic summits direct water outward along radial slopes.

4

Analyze Dendritic Drainage Pattern

Dendritic drainage exhibits a random branching tree-like structure without structural alignment.

Uniform rock resistance (lithology) allows equal erosion in all directions.

Cevap

The correct pairings are: (1) A vertical rise of 50 m across 4 cm on a 1:25,000 map matches 1 in 20 (5.0%); (2) An elevation change from 120 m to 320 m over 5 cm on a 1:50,000 map matches 1 in 12.5 (8.0%); (3) A rise of 150 m over 6 cm on a 1:25,000 map matches 1 in 10 (10.0%); (4) Crossing 4 contour intervals of 20 m across 4 cm at 1:100,000 scale matches 1 in 50 (2.0%).

Each scenario is accurately paired by converting the map distance to actual ground distance in meters using the given scale, determining the vertical interval, and computing the gradient as a ratio (1 in N) and percentage.

Adım Adım Çözüm

1

Convert the map distance for each scenario into the ground horizontal distance (Horizontal Equivalent, HE) in meters using the designated map scale.

Scenario 1:

4\text{ cm} \times 25,000 / 100 = 1,000\text{ m}

. Scenario 2:

5\text{ cm} \times 50,000 / 100 = 2,500\text{ m}

. Scenario 3:

6\text{ cm} \times 25,000 / 100 = 1,500\text{ m}

. Scenario 4:

4\text{ cm} \times 100,000 / 100 = 4,000\text{ m}

.

Map scale Representative Fractions convert map measurements to real ground horizontal distances, which must be expressed in meters to match the unit of Vertical Interval.

2

Calculate the total height difference (Vertical Interval, VI) in meters for each terrain scenario.

Scenario 1:

\text{VI} = 50\text{ m}

. Scenario 2:

\text{VI} = 320\text{ m} - 120\text{ m} = 200\text{ m}

. Scenario 3:

\text{VI} = 150\text{ m}

. Scenario 4:

\text{VI} = 4 \text{ intervals} \times 20\text{ m} = 80\text{ m}

.

Vertical Interval represents the net vertical relief difference between the start and end points of the transect.

3

Compute the gradient ratio (VI / HE) and express it both as a simple ratio (1 in N) and as a percentage slope.

Scenario 1:

\frac{50}{1,000} = \frac{1}{20} \rightarrow 1 \text{ in } 20

(

5.0\%

). Scenario 2:

\frac{200}{2,500} = \frac{1}{12.5} \rightarrow 1 \text{ in } 12.5

(

8.0\%

). Scenario 3:

\frac{150}{1,500} = \frac{1}{10} \rightarrow 1 \text{ in } 10

(

10.0\%

). Scenario 4:

\frac{80}{4,000} = \frac{1}{50} \rightarrow 1 \text{ in } 50

(

2.0\%

).

Gradient formula is

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

Soldaki öğeye tıklayın, sonra eşleşen sağdaki öğeye tıklayın

Cevabı ve açıklamayı göster

Cevap

The correct pairings match each regional soil conservation practice in Nigeria to its target soil type and degradation mechanism: Shelterbelts in northern states control wind erosion on loose Regosols; Gabion check dams and revegetation in Southeastern escarpments stabilize deep gully erosion on friable sandy Ferrallitic soils; Terracing and contour ridging on the Jos Plateau prevent sheet erosion on shallow highland Ferruginous soils; Dykes and drainage controls in the Niger Delta manage tidal flooding and salinization in coastal Hydromorphic soils.

Each pair correctly links a distinct Nigerian geographic region and soil conservation method with its specific soil degradation process and soil group. Shelterbelts stabilize light-textured northern Regosols against wind erosion; gabions and biological planting remediate catastrophic gully erosion in deep Southeastern sandy Ferrallitic soils; stone terracing limits sheet erosion on Jos Plateau Ferruginous soils; and coastal bunds manage flooding/salinization in Niger Delta Hydromorphic soils.

Adım Adım Çözüm

1

Analyze Northern Nigerian environmental conditions and soil conservation responses.

Alfred Weber's theory of industrial location classifies plants based on whether they are material-oriented, market-oriented, power-oriented, or footloose.

2

Pair each industry with its corresponding spatial determinant.

Aluminum Smelting -> Cheap power supply; Iron and Steel -> Weight-loss raw material deposits; Soft Drink Bottling -> Market proximity due to weight gain; Semiconductor Assembly -> Footloose location flexibility.

Matching transport costs and production constraints minimizes overall production and distribution costs per Weberian theory.

Cevap

Ramsar Convention matches Protection and sustainable use of wetlands of international importance; Montreal Protocol matches Phasing out the production and usage of ozone-depleting substances; Kyoto Protocol matches Legally binding targets to reduce greenhouse gas emissions; Basel Convention matches Control of transboundary movements of hazardous wastes and their disposal.

Each international agreement targets a distinct global environmental challenge: the Ramsar Convention preserves wetlands; the Montreal Protocol phases out ozone-depleting chemicals; the Kyoto Protocol addresses greenhouse gas mitigation; and the Basel Convention controls toxic waste transportation.

Adım Adım Çözüm

1

Identify the main mandate of the Ramsar Convention.

Ramsar is focused on wetlands conservation.

Signed in Ramsar, Iran in 1971, its core objective is protecting wetland ecosystems globally.

2

Identify the primary objective of the Montreal Protocol.

Montreal targets substances that damage the ozone layer.

Adopted in 1987 to control chemical pollutants like CFCs and halons.

3

Identify the key focus of the Kyoto Protocol.

Kyoto targets climate change and greenhouse gases.

Adopted under UNFCCC in 1997 to enforce emission reduction targets.

4

Identify the objective of the Basel Convention.

Basel governs hazardous waste management and movement.

Adopted in 1989 to stop dumping of toxic waste across borders.

Cevabı ve açıklamayı göster

Cevap

Carbonation matches with the dissolution of limestone by carbonic acid; Hydrolysis matches with chemical alteration forming clay minerals; Solifluction matches with saturated soil flow over permafrost; Soil Creep matches with imperceptibly slow downslope movement causing tilted poles.

Each geographical process corresponds directly to its scientific mechanism: Carbonation dissolves calcium carbonate in limestone landscapes; Hydrolysis decomposes minerals into clay; Solifluction represents saturated soil flow over permafrost; Soil Creep is an ultra-slow downslope creep under gravity.

Adım Adım Çözüm

1

Differentiate between chemical weathering mechanisms

Carbonation involves the action of carbonic acid on limestone, whereas hydrolysis is the chemical breakdown of silicate minerals into clay via reaction with water ions.

Chemical weathering alters the chemical composition of rocks in place.

2

Distinguish between types and conditions of mass wasting

Solifluction is a specific flow process occurring over impermeable frozen subsoil in tundra/periglacial zones, while soil creep is an extremely slow, continuous downslope movement driven by gravity across temperate and tropical slopes.

Mass wasting processes are classified by movement rate, water content, and climatic environment.

Cevap

Pastoral Nomadism matches seasonal livestock movement across natural pastures; Mediterranean Farming matches specialized commercial cultivation of citrus fruits, olives, and grapes; Commercial Grain Farming matches extensive, highly mechanized monoculture focused primarily on wheat; and Shifting Cultivation matches rotational plot clearing using slash-and-burn methods with long fallow periods.

Each agricultural system is correctly paired with its defining environmental and economic operational method: Pastoral nomadism relies on seasonal mobility; Mediterranean farming focuses on specialized fruit and olive orchards; commercial grain farming uses heavy mechanization for vast wheat fields; and shifting cultivation uses rotational slash-and-burn field clearing.

Adım Adım Çözüm

1

Identify the core operational mechanism of Pastoral Nomadism.

It involves herdsmen migrating with livestock searching for natural pasture and water sources.

Nomadic pastoralists do not cultivate fixed crop fields; their land use is extensive and mobile.

2

Identify the characteristic crops of Mediterranean Farming.

It is widely recognized for viticulture, citrus fruits, olives, and winter wheat.

The Mediterranean climate regime favours summer drought-resistant tree and vine crops.

3

Identify the defining features of Commercial Grain Farming.

It utilizes extensive machinery on large farms to grow single grain crops like wheat for export markets.

This agricultural system is capital-intensive and requires flat terrain for tractor and combine harvester operations.

4

Identify the soil management technique in Shifting Cultivation.

Fields are cleared by burning vegetation, farmed temporarily, and left fallow to regenerate soil fertility.

Tropical soils leach nutrients quickly under continuous cropping without synthetic fertilizer inputs.
