Items

Laccolith
Lopolith
Phacolith
Batholith

Matches

Show answer & explanation

Answer

Laccolith corresponds to the dome-shaped intrusion with a planar horizontal base; Lopolith corresponds to the saucer-shaped body concave toward the sky; Phacolith corresponds to the lens-shaped body at fold crests or troughs; Batholith corresponds to the massive plutonic rock body forming mountain cores.
Each intrusive landform is correctly matched to its specific structural morphology: Laccolith to the dome shape with a flat base, Lopolith to the saucer-shaped concave structure, Phacolith to the lens-shaped fold hinge intrusion, and Batholith to the massive granitic plutonic body.

Step-by-Step Solution

1
Analyze the structural geometry of Laccolith
Laccolith matches with the dome-shaped intrusion having a flat horizontal base and a pipe feeder.
Viscous magma forces the overlying strata to arch upward, creating a dome structure over a flat base.
2
Analyze the structural geometry of Lopolith
Lopolith matches with the saucer-shaped intrusive body concave toward the sky.
As magma intrudes into structural basins, sagging under gravity produces a characteristic saucer shape.
3
Analyze the structural placement of Phacolith
Phacolith matches with the lens-shaped magma mass localized at anticline crests or syncline troughs.
Differential stresses during crustal folding create space at fold hinges for lens-like magma accumulation.
4
Analyze the structural characteristics of Batholith
Batholith matches with the massive granitic plutonic body forming mountain cores.
Batholiths represent the largest plutonic intrusions, forming deep beneath mountain systems.

Question 65Question →

Which of the following statements regarding the atmospheric circulation, extratropical disturbances, and seasonal driving mechanisms of the Indian climate are correct?

Select all that apply

Show answer & explanation

Answer: The establishment of the Tropical Easterly Jet Stream over peninsular India is directly linked to the northward displacement of the Subtropical Westerly Jet Stream to the north of the Tibetan Plateau.; Western Disturbances originate as extratropical cyclones over the Mediterranean region and are carried towards northwestern India by the Subtropical Westerly Jet Stream during winter.

Answer

The correct statements are the one regarding the relationship between the Tropical Easterly Jet Stream and the northern displacement of the Subtropical Westerly Jet Stream, and the statement describing Western Disturbances as extratropical cyclones originating over the Mediterranean driven by the Subtropical Westerly Jet Stream.
The statement explaining the emergence of the Tropical Easterly Jet Stream is correct because the seasonal shift of the Subtropical Westerly Jet to the north of Tibet is a necessary structural condition for the upper-level Easterly Jet and ITCZ northward movement. The statement regarding Western Disturbances is also correct because these non-monsoonal storms originate over the Mediterranean and move along the upper westerly flow into North India during winter.

Step-by-Step Solution

1
Analyze the upper-atmospheric mechanisms governing the onset of the Indian Southwest Monsoon.
During summer, intense heating of the Tibetan Plateau generates an upper-level warm anticyclone. For the Tropical Easterly Jet Stream to form over southern India, the winter Subtropical Westerly Jet Stream must first retreat to the north of the Himalayas. Hence, the statement linking the establishment of the Tropical Easterly Jet Stream to this northward displacement is accurate.
Upper-air jet stream transitions serve as a primary trigger for atmospheric pressure reversals over South Asia.
2
Evaluate the origin and steering mechanism of Western Disturbances.
Western Disturbances are temperate (extratropical) low-pressure systems originating in the Mediterranean and Atlantic regions. They travel eastward under the influence of the upper-tropospheric Subtropical Westerly Jet Stream, bringing winter precipitation to northwestern India. Thus, the statement describing Western Disturbances is correct.
Extratropical storm tracks in winter are governed by upper-level westerly wind belts.
3
Examine the spatial SST anomaly pattern of the positive Indian Ocean Dipole (IOD).
A positive IOD phase consists of anomalous warming in the western Indian Ocean and cooling in the southeastern tropical Indian Ocean. This thermal gradient strengthens the cross-equatorial flow and boosts monsoon rainfall over India. The statement claiming warmer eastern waters and suppressed rainfall reverses the positive IOD anomaly dynamics and is incorrect.
Ocean-atmosphere coupling parameters like the IOD modify regional atmospheric moisture transport.
4
Assess the seasonal origin of pre-monsoon convective showers in southern India.
Mango Showers occur during the pre-monsoon summer season (April to May) as a result of localized solar insolation and convection cell formation over peninsular India. They are distinct from the retreating northeast monsoon that occurs between October and December. Therefore, attributing them to the retreating monsoon is false.
Pre-monsoon local thunderstorms arise from thermal instability, not winter wind reversal patterns.

Consider the following statements regarding global agricultural systems and economic activities:

1. Mediterranean agriculture is a highly specialized commercial farming system where viticulture (grape cultivation) is a primary specialty.
2. Transhumance refers to the seasonal migration of pastoral herders and their livestock between mountain pastures in summer and valley floors in winter.
3. Intensive commercial grain farming is predominantly practiced in the densely populated tropical rainforest regions of Southeast Asia.

Which of the statements given above are correct?

Show answer & explanation

Answer: 1 and 2 only

Answer

Statements 1 and 2 are correct. Statement 3 is incorrect because commercial grain farming is predominantly practiced in the mid-latitude temperate grasslands (such as the Eurasian Steppes, North American Prairies, Argentine Pampas, and Australian Downs), whereas tropical rainforests of Southeast Asia are predominantly associated with intensive subsistence agriculture, shifting cultivation, or plantation agriculture.
The combination stating '1 and 2 only' is correct. Mediterranean agriculture is famous for viticulture, citrus fruits, and olives. Transhumance correctly describes vertical seasonal pastoral migration. Commercial grain farming is restricted to temperate grassland regions of the world, making the third statement incorrect.

Step-by-Step Solution

1
Evaluate Statement 1 regarding Mediterranean agriculture
Statement 1 is TRUE.
Mediterranean agriculture is intensive, highly specialized commercial farming surrounding the Mediterranean Sea, California, central Chile, and parts of South Africa/Australia. Viticulture is a hallmark of this climate zone alongside citrus fruit production.
2
Evaluate Statement 2 regarding transhumance
Statement 2 is TRUE.
Transhumance is a pastoral practice observed in mountainous regions (e.g., the Alps, Himalayas, Andes) where pastoral communities move up to high pastures during warm summer months and return to lower valleys in winter.
3
Evaluate Statement 3 regarding commercial grain farming distribution
Statement 3 is FALSE.
Extensive commercial grain farming requires large farm landholdings and mechanization, which occur in semi-arid mid-latitude continental grasslands, not humid, densely populated tropical rainforest environments.

Consider the following statements regarding the propagation of seismic waves through the Earth's interior:

1. Primary waves (PP-waves) are longitudinal in nature and can pass through solid, liquid, and gaseous media.
2. Secondary waves (SS-waves) are transverse waves and can travel only through solid materials.
3. The shadow zone for SS-waves is smaller in spatial extent than the shadow zone for PP-waves.

Which of the statements given above is/are correct?

Show answer & explanation

Answer: 1 and 2 only

Answer

1 and 2 only
The correct response identifies statements 1 and 2 as accurate. PP-waves are compressional (longitudinal) waves capable of propagating through solids, liquids, and gases. SS-waves are shear (transverse) waves that propagate exclusively through solids. The SS-wave shadow zone is significantly larger than the PP-wave shadow zone because SS-waves cannot pass through the liquid outer core, receiving no direct SS-waves beyond 103∘103^\circ from the epicenter worldwide.

Step-by-Step Solution

1
Evaluate Statement 1 regarding P-waves
Statement 1 is correct. Primary waves are longitudinal waves where particles vibrate parallel to wave direction; they travel through solids, liquids, and gases.
Compressional mechanics allow longitudinal motion across all material states.
2
Evaluate Statement 2 regarding S-waves
Statement 2 is correct. Secondary waves are transverse shear waves; liquid media lack shear strength, so S-waves pass only through solids.
Fluid bodies cannot sustain shear stress.
3
Evaluate Statement 3 comparing shadow zone extents
Statement 3 is incorrect. Because S-waves cannot travel through the liquid outer core, their shadow zone forms an extensive zone beyond 103∘103^\circ from the epicenter. In contrast, the P-wave shadow zone exists only as a band between 103∘103^\circ and 142∘142^\circ. Thus, the S-wave shadow zone is significantly larger.
Complete blockage of S-waves by the liquid outer core creates a larger global shadow area than the refractive bending of P-waves.

Answer

Statements 1, 2, and 4 are correct.
The option selecting statements 1, 2, and 4 only is correct because Meghalaya is geologically a part of the Peninsular Plateau (separated by the Malda fault), Karewas are lacustrine deposits essential for saffron cultivation, and the passes Zoji La, Shipki La, Lipulekh, and Nathu La correctly follow a West-to-East sequence. Statement 3 is false because Western Ghats are fault escarpments, not young collision fold mountains.

Step-by-Step Solution

1
Analyze Statement 1 regarding Peninsular Block extensions.
Statement 1 is TRUE. The Shillong (Meghalaya) and Karbi Anglong Plateaus in the northeast are detached portions of the Indian Peninsular Plateau separated by the Rajmahal-Garo gap / Malda Fault.
Geological faulting created a downward gap between the Chota Nagpur Plateau and the Meghalaya block.
2

Consider the following statements regarding winter atmospheric circulation and precipitation mechanisms over the Indian subcontinent:

1. The Subtropical Westerly Jet Stream shifts south of the Himalayas during winter, splitting into two distinct branches due to the physical barrier of the Tibetan Plateau.
2. Western Disturbances, which bring vital winter rainfall to northwestern India, are steered across Eurasia into the subcontinent by the Tropical Easterly Jet Stream.
3. The winter rainfall along the Coromandel Coast of Tamil Nadu is predominantly caused by the moisture-laden winds of the North-East Monsoon picking up moisture over the Bay of Bengal.

Which of the statements given above are correct?

Show answer & explanation

Answer: 1 and 3 only

Answer

The correct statements are 1 and 3 only.
The southern branch of the Subtropical Westerly Jet Stream flows south of the Himalayas during winter and guides mid-latitude extratropical cyclones (Western Disturbances) into northwestern India. Simultaneously, the North-East Monsoon winds cross the Bay of Bengal, gather moisture, and bring rainfall to the Coromandel Coast.

Step-by-Step Solution

1
Evaluate Statement 1 regarding winter upper-air circulation
Statement 1 is correct
During the northern hemisphere winter, the southward shift of the Inter-Tropical Convergence Zone (ITCZ) draws the Subtropical Westerly Jet Stream south of the Himalayas. The high-altitude Tibetan Plateau acts as a mechanical barrier, splitting the jet stream into northern and southern branches.
2
Evaluate Statement 2 regarding the steering mechanism of Western Disturbances
Statement 2 is incorrect
Western Disturbances are shallow cyclonic depressions originating over the Mediterranean region. They are driven eastward into northwestern India by the southern branch of the Subtropical Westerly Jet Stream during winter. The Tropical Easterly Jet Stream (TEJ) is active only during the summer monsoon months.
3
Evaluate Statement 3 regarding Coromandel Coast precipitation
Statement 3 is correct
During winter (October to December), dry land-to-sea winds of the North-East Monsoon blow across the Bay of Bengal, picking up significant moisture before striking the Coromandel Coast of Tamil Nadu and producing rainfall.

Which of the following statements regarding global atmospheric pressure belts and planetary wind systems are correct?

Select all that apply

Show answer & explanation

Answer: The Subtropical High-Pressure Belts are dynamically induced pressure zones formed due to the subsidence and accumulation of air descending from the upper atmosphere.; The Mediterranean region receives the bulk of its annual rainfall during the winter season due to the seasonal equatorward shift of the Westerlies.

Answer

The statements confirming the dynamic origin of Subtropical High-Pressure Belts via subsidence of air aloft and the winter precipitation mechanism of the Mediterranean climate caused by the equatorward migration of Westerlies are correct.
The dynamic origin of Subtropical High-Pressure Belts is correctly attributed to air subsidence around 30∘30^\circ latitude following upper-atmospheric divergence from the equator. Additionally, winter rainfall in Mediterranean climates is accurately explained by the seasonal southward migration of pressure belts, bringing rain-bearing Westerlies over these regions.

Step-by-Step Solution

1
Analyze the formation mechanism of Subtropical High-Pressure Belts.
Confirm that the rising air at the equator subsides near 30∘30^\circ latitude owing to upper-air divergence and Coriolis deflection, confirming its dynamic origin.
Pressure belts created by mechanical movement and air sinking rather than thermal heating are dynamically induced.
2
Evaluate the directional orientation of Southern Hemisphere Trade winds.
Identify that winds moving from 30∘ S30^\circ\text{ S} toward the equator are deflected leftward, forming South-East Trades (blowing from SE to NW).
Wind direction is named after the direction from which the wind originates, not the direction toward which it blows.
3
Examine the seasonal shift of wind belts impacting Mediterranean climate.
Confirm that overhead Sun movement in winter causes pressure belts to shift equatorward, placing Mediterranean latitudes directly in the path of moist oceanic Westerlies.
Seasonal migration of pressure belts drives rain during winter in Mediterranean zones while keeping summers dry under subtropical high influence.
4
Verify the characteristic properties and direction of Polar Easterlies.
Recognize that Polar Easterlies originate from polar thermal highs, bringing cold, dry continental air toward sub-polar low pressure areas.
Air flows from high pressure to low pressure, making the assertion that polar easterlies flow towards polar highs incorrect.

Show answer & explanation

Answer: Ramganga

Answer

The Ramganga River is the first major left-bank tributary of the Ganga River system, meeting it at Kannauj.
The Ramganga River rises in the Dudhatoli hills of Chamoli district, Uttarakhand. It flows through Corbett National Park before descending into the plains near Kalagarh and joining the Ganga on its left bank near Kannauj, making it the first major left-bank tributary of the Ganga system.

Step-by-Step Solution

1
Identify the drainage course and major left-bank tributaries of the Ganga River from West to East.
The major left-bank tributaries in order from source to mouth are Ramganga, Gomti, Ghaghara, Gandak, Burhi Gandak, Kosi, and Mahananda.
Geographical orientation along the upper and middle Ganga plains dictates the order of confluence points.
2
Locate the confluence point near Kannauj in western Uttar Pradesh.
The Ramganga River, after exiting the Shivalik range and flowing through Garhwal and western Uttar Pradesh, meets the Ganga at Kannauj.
This establishes Ramganga as the westernmost and first major left-bank tributary joining the main Ganga stem in the plains.

Arrange the following seas/water bodies in correct order of their geographical location from North to South.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct arrangement from North to South is Baltic Sea, Mediterranean Sea, Red Sea, and Arabian Sea.
The Baltic Sea occupies the northernmost position among the listed water bodies in Northern Europe. Below it lies the Mediterranean Sea between Europe and Africa, followed by the Red Sea separating Africa from the Arabian Peninsula, and finally the Arabian Sea in the northern region of the Indian Ocean.

Step-by-Step Solution

1
Determine the approximate latitudinal position of each given water body.
Baltic Sea (~54°N to 66°N), Mediterranean Sea (~30°N to 45°N), Red Sea (~12°N to 30°N), Arabian Sea (~0°N to 25°N).
Degrees of latitude north of the Equator decrease as one moves southward.
2
Sequence the features from highest latitude (furthest north) to lowest latitude (furthest south).
Baltic Sea → Mediterranean Sea → Red Sea → Arabian Sea.
This reflects the correct geographic order from North to South.
