Cevabı ve açıklamayı göster

Cevap

Equatorial (Tropical Rainforest) Zone → Tropical Savanna (Sudan) Zone → Mediterranean Zone → Tropical Desert (Sahara/Namib) Zone
The correct sequence arranges the climate zones from lowest annual temperature range to highest. The Equatorial Zone has the smallest range (2∘C−3∘C2^\circ\text{C}-3^\circ\text{C}) due to constant insolation and cloudiness. The Tropical Savanna Zone has a slightly higher range (5∘C−9∘C5^\circ\text{C}-9^\circ\text{C}) due to seasonal dry periods. The Mediterranean Zone experiences wider seasonal shifts (10∘C−14∘C10^\circ\text{C}-14^\circ\text{C}) due to higher latitudes. The Tropical Desert Zone experiences the largest annual range (15∘C−20∘C+15^\circ\text{C}-20^\circ\text{C}+) due to hyper-aridity and cloudless skies.

Adım Adım Çözüm

1
Analyze the thermal controls governing Equatorial regions.
Near the equator, uniform day length and high moisture yield an annual temperature range of only 2∘C−3∘C2^\circ\text{C} - 3^\circ\text{C}, placing the Equatorial Zone first.
Cloud cover and high humidity prevent extreme seasonal temperature variations.
2
Evaluate the seasonal temperature variations in the Tropical Savanna Zone.
Alternating wet and dry seasons yield an annual temperature range of roughly 5∘C−9∘C5^\circ\text{C} - 9^\circ\text{C}, placing it second.
Clear skies during the dry season increase solar radiation compared to the humid equatorial belt.
3
Assess thermal conditions in the Mediterranean climate regions.
Higher latitude location leads to distinct winter and summer thermal regimes with an annual temperature range of 10∘C−14∘C10^\circ\text{C} - 14^\circ\text{C}, placing it third.
Subtropical location introduces marked seasonal differences in solar elevation.
4
Examine extreme temperature ranges in continental dry climates.
Extremely dry air and cloudless conditions in the Tropical Desert Zone lead to strong diurnal and seasonal radiative losses, yielding the largest annual temperature range (15∘C−20∘C+15^\circ\text{C} - 20^\circ\text{C}+), placing it last.
Lack of moisture and vegetation allows maximum surface heating during summer and rapid radiational cooling during winter.

Suppose a research expedition travels due north across the African continent along the 20°E meridian, starting from the Congo Basin near the Equator and terminating at the coast of North Africa. In what sequence will the expedition encounter these major vegetation zones from south to north?

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct spatial sequence from south to north starting at the Equator is Tropical Rainforest, followed by Sudan Savanna, then Sahel Semi-Arid Scrub, and finally Mediterranean Woodland along the northern coast.
Traveling northward from the Equator (0°) toward North Africa, increasing distance from the Intertropical Convergence Zone causes rainfall to decrease and dry seasons to lengthen. This creates a distinct south-to-north latitudinal sequence: Tropical Rainforest, Sudan Savanna, Sahel Semi-Arid Scrub, and Mediterranean Woodland.

Adım Adım Çözüm

1
Identify the Equatorial vegetation belt
Tropical Rainforest occupies the low-latitude humid region around the Equator (~0°).
High temperatures and heavy year-round rainfall in the Congo Basin support dense evergreen rainforest.
2
Trace the northward transition into savanna
Sudan Savanna lies north of the rainforest belt (~8°N to 12°N).
Decreasing annual rainfall and a seasonal dry period lead to open savanna woodland.
3
Identify the semi-arid desert border zone
Sahel Semi-Arid Scrub forms a narrow band (~12°N to 18°N) directly south of the Sahara Desert.
Low annual rainfall (~200–600 mm) supports only drought-resistant thorny acacias and sparse grasses.
4
Determine the northern coastal vegetation belt
Mediterranean Woodland covers the northernmost coast of North Africa (~30°N to 37°N).
Winter rainfall and dry summer conditions along the Mediterranean coast favor sclerophyllous shrubs and trees.

Arrange the following sequential stages in the progressive marine erosion of a rocky headland, from the initial concentration of wave energy to its final reduced landform.

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct sequence of headland erosion begins with the formation of a sea cave, followed by its evolution into a sea arch, the collapse of the arch roof into a sea stack, and the final degradation of the stack into a sea stump.
Headland erosion follows a predictable geomorphic sequence: wave action exploits joints to form a sea cave, which enlarges into a sea arch. Subaerial weathering and gravity cause the arch roof to collapse into a detached sea stack, which is finally undercut by waves to leave a sea stump.

Adım Adım Çözüm

1
Identify the initial erosional feature created where waves attack lines of weakness along a cliff base.
Marine forces excavate lines of structural weakness to produce a sea cave.
Hydraulic action and abrasion act first on weak joints at sea level.
2
Determine the landform created when wave erosion breaches completely through the headland.
The cave opens up through the headland, creating a sea arch.
Erosion from both sides of the headland meets or drives entirely through the wall.
3
Analyze the structural collapse of the unsupported arch roof due to subaerial processes and gravity.
The arch roof falls, leaving an isolated vertical column known as a sea stack.
Weathering destabilizes the roof, isolating the outer wall from the mainland.
4
Trace the final marine undercutting of the isolated pillar.
Wave action undercuts the base of the pillar, reducing it to a low sea stump.
Direct wave energy at the base destabilizes the stack until only a low remnant remains.

Cevap

The correct geographical sequence from North to South along the Trans-Saharan Highway (TAH 2) is Algiers, Tamanrasset, Agadez, Kano, and Lagos.
The Trans-Saharan Highway (TAH 2) connects Mediterranean North Africa directly to Atlantic West Africa. The geographical progression from North to South begins at Algiers on the Mediterranean coast of Algeria (36.7∘N36.7^\circ\text{N}), moves inland through Tamanrasset in southern Algeria (22.8∘N22.8^\circ\text{N}), crosses into Niger at Agadez (17.0∘N17.0^\circ\text{N}), proceeds into northern Nigeria at Kano (12.0∘N12.0^\circ\text{N}), and ends at Lagos on the Atlantic coast (6.5∘N6.5^\circ\text{N}).

Adım Adım Çözüm

1
Identify the northernmost coastal terminus of the highway corridor.
Algiers (Algeria) situated at approximately 36.7∘N36.7^\circ\text{N} on the Mediterranean Sea.
The corridor originates on the North African coast of the Mediterranean.
2
Trace the highway southward through the Algerian Saharan interior.
Tamanrasset (Algeria) situated at approximately 22.8∘N22.8^\circ\text{N}.
Tamanrasset is the main urban hub in the Ahaggar region of southern Algeria before reaching the border.
3
Follow the corridor across the international border into northern/central Niger.
Agadez (Niger) situated at approximately 17.0∘N17.0^\circ\text{N}.
Agadez links northern Saharan trade routes to the West African Sahel region.
4
Trace the route south into the savanna zone of West Africa.
Kano (Nigeria) situated at approximately 12.0∘N12.0^\circ\text{N}.
Kano is a major historic trade center connecting trans-Saharan commerce to the West African forest and coastal zones.
5
Identify the southern Atlantic port terminus of the corridor.
Lagos (Nigeria) situated at approximately 6.5∘N6.5^\circ\text{N}.
Lagos serves as the southern maritime industrial outlet on the Atlantic Ocean.

In glaciated highland regions, frost action and glacial movement progressively transform mountain slopes into distinctive alpine landforms over time. Arrange the following geomorphic stages in the correct chronological order of their evolutionary sequence, from the initial process to the final landform.

Cevap

The correct sequence of glacial landform evolution is: (1) Snow accumulation and nivation in a mountain hollow, (2) Deepening into an armchair-shaped cirque by rotational ice flow and plucking, (3) Headward erosion of adjacent cirques into a central mountain mass, and (4) Isolation of a sharp pyramidal peak.
Alpine glacial landscape evolution begins with perennial snow accumulation and freeze-thaw nivation in mountain depressions. As ice builds up, rotational sliding and basal plucking deepen these hollows into armchair-shaped cirques. When three or more surrounding cirques erode headward into the same central mountain summit, the narrowing dividing ridges converge to leave a sharp, steep-sided pyramidal peak.

Adım Adım Çözüm

1
Identify the initial process
Snow accumulates in a pre-existing depression, where freeze-thaw action (nivation) disintegrates rock.
Glacial erosion starts with snow accumulation and freeze-thaw weathering before a full glacier forms.
2
Determine the formation of the cirque basin
Ice accumulation produces rotational movement, plucking the backwall and scouring the hollow floor.
Plucking steepens the backwall while abrasion deepens the basin, creating a classic cirque.
3
Trace multi-directional headward erosion
Three or more cirques located on different sides of a mountain erode headward toward the summit.
Backwards erosion narrows the dividing rock ridges into knife-edge arêtes.
4
Identify the final residual landform
A steep, horn-like pyramidal peak is left isolated at the junction of the converging arêtes.
Continuous cirque recession from all sides meets at a central point, forming a horn/pyramidal peak.
