Q1On a globe, the boundary separating the sunlit half from the dark half is observed at a given moment. Which conclusion is correct?
A It is the Arctic Circle, because high latitudes control sunrise and sunset everywhere.
B It is the Equator, because the Equator always separates day from night.
C It is the circle of illumination, and it does not necessarily coincide with the Earth's axis.
D It is the Prime Meridian, because 0 degree longitude fixes the start of daylight.
Explanation At any instant, the spherical Earth has one half facing the Sun and another half away from it. The line or circle separating these halves is called the circle of illumination; because of axial inclination, it should not be treated as the Equator, Prime Meridian, or axis.
Q2In the vertical structure of the atmosphere, which layer is most directly associated with day-to-day weather phenomena such as rainfall, fog and hailstorm?
A Troposphere
B Mesosphere
C Stratosphere
D Exosphere
Explanation The troposphere is the lowermost and most important atmospheric layer for human life. It holds most of the air we breathe along with dust particles and water vapour, so rainfall, fog, hailstorm and other day-to-day weather changes occur mainly in this layer.
Q3Consider the drainage of Peninsular India. Which statement is most accurate?
A The Godavari and Krishna flow westward through rift valleys into the Arabian Sea.
B The Mahanadi, Godavari and Kaveri all empty into the Arabian Sea after crossing the Western Ghats.
C The Narmada and Tapi are major west-flowing rivers, while most large Peninsular rivers drain into the Bay of Bengal.
D The Indus, Ganga and Brahmaputra are classified as Peninsular rivers because they cross the plains.
Explanation Indian drainage is commonly grouped into Himalayan and Peninsular systems and also by outflow towards the Bay of Bengal or the Arabian Sea. In Peninsular India, the Godavari, Krishna, Mahanadi and Kaveri are east-flowing systems, whereas the Narmada and Tapi are notable larger rivers flowing westward to the Arabian Sea.
Q4A teacher is explaining why the Tamil Nadu coast receives a significant part of its rainfall after the main southwest monsoon season. Which explanation is most appropriate?
A The coast lies on the windward side of the Arabian Sea branch throughout June and July.
B Retreating monsoon winds over the Bay of Bengal pick up moisture and give rain to the Coromandel Coast.
C Western disturbances become strongest over the Coromandel Coast in May.
D The Thar Desert creates local convection that directly feeds cyclonic rain over Tamil Nadu.
Explanation Tamil Nadu is relatively rain-shadowed during much of the southwest monsoon. Its important rainfall period comes with the retreating or north-east monsoon phase, when winds moving over the Bay of Bengal gain moisture and bring rain to the Coromandel Coast, often aided by cyclonic disturbances.
Q5Which crop-climate association is correctly matched for Indian agriculture?
A Rice - high temperature, high humidity and assured water supply during the growing season
B Jute - dry desert climate and sandy soil with very low rainfall
C Wheat - high humidity, standing water and uniformly high temperature throughout growth
D Tea - saline coastal flats with no need for rainfall or slope
Explanation Rice is strongly linked with warm and moist Kharif conditions, especially where rainfall or irrigation can maintain water supply. Wheat, by contrast, is a Rabi crop requiring cooler growth and dry, sunny conditions at ripening, so confusing the two is a common exam distractor.

6In the sea-floor spreading model, which combination of observations most directly supports creation of new oceanic crust at mid-oceanic ridge crests and its later consumption near trenches?
AOldest ocean-floor rocks at ridge crests, thickest sediments near ridge crests, and shallow earthquakes mainly at trenches
BMaximum sediment thickness at mid-oceanic ridges, reverse polarity only near trenches, and older crust toward ridge crests
CUniform ages of all oceanic and continental rocks, absence of volcanism at ridges, and no earthquake concentration near plate margins
DVolcanic eruptions along ridges, matching age and magnetic properties of equidistant rocks on both sides of the ridge crest, younger rocks near the crest, and deep-seated earthquakes near trenches
7A student says, 'Latitude and longitude are both imaginary lines, so they must run in the same direction.' Which correction is best?
ABoth latitude and longitude run from pole to pole, but latitude alone measures time.
BLatitudes join the North and South Poles, while longitudes are circles parallel to the Equator.
CLatitudes are parallel circles measured north or south of the Equator, while longitudes are meridians measured east or west of the Prime Meridian.
DLatitudes and longitudes are physical lines marked on the Earth's surface at equal spacing everywhere.
8For Rajasthan's transport and trade geography, which planning argument is the most internally consistent?
AA transport strategy that improves multimodal connectivity, road safety, freight permits and cleaner urban mobility supports Rajasthan's mineral belts, agro-processing clusters and large urban markets together.
BThe best trade strategy is to isolate western desert districts from state highways because low density makes movement of minerals and livestock products unnecessary.
CBecause Rajasthan's trade is almost entirely coastal, inland road safety, permits and multimodal public transport have little connection with economic geography.
DElectric mobility policies are relevant only to Himalayan hill states, so Jaipur, Jodhpur, Kota, Udaipur, Bikaner, Ajmer, Bharatpur and Alwar are outside Rajasthan's transport priorities.
9Which group correctly represents biodiversity hotspots that have a geographical presence in India?
AEastern Ghats, Thar Desert, Central Highlands and Ganga Plain
BHimalaya, Indo-Burma, Western Ghats and Sri Lanka, and Sundaland
CMediterranean Basin, Caucasus, Japan and Cape Floristic Region
DArctic Tundra, Sahara-Sahel, Andes and Great Barrier Reef
10Which volcanic-landform statement is most accurate for differentiating eruption type and surface form?
AFlood basalt provinces are formed by small, steep cinder cones from a single vent.
BCalderas are tall cones built by quiet accumulation of thin basalt flows.
CShield volcanoes are broad, gently sloping forms built largely by fluid basaltic lava flows.
DComposite volcanoes are the least explosive volcanoes and never include pyroclastic material.
11For Rajasthan, which set of statements best captures the Aravalli-controlled contrast between physical features and drainage?
AThe highest relief of Rajasthan is in the north-eastern Khetri belt, and the western desert improves only towards Jaisalmer.
BGuru Shikhar-Mount Abu to Khetri is the broad Aravalli axis; north-west of it lies the larger sandy, water-scarce tract, while the south-east has higher, more fertile terrain and the Chambal badland belt.
CThe south-eastern part is the drier half because the Chambal badlands prevent alluvial plains from forming in eastern Rajasthan.
DThe Aravalli axis is mainly an east-west barrier near the Chambal, so the Thar Desert lies chiefly south of Kota and Bundi.
12Which conclusion follows most directly from the observed shadow zones of earthquake waves?
AThe absence of S-waves beyond about 105 degrees supports the inference of a liquid outer core.
BS-waves travel faster than P-waves and therefore arrive first at distant seismographs.
CP-waves cannot pass through liquids, so their absence beyond 105 degrees proves the mantle is liquid.
DSurface waves reveal the core best because they travel through the Earth's body before reaching the surface.
13Ignoring legal time-zone boundaries, what is the local-time difference between Greenwich at 0 degree longitude and a place at 75 degrees E?
A75 minutes behind Greenwich
B3 hours ahead of Greenwich
C5 hours behind Greenwich
D5 hours ahead of Greenwich
14Which statement most accurately distinguishes denudation from diastrophism in geomorphology?
ADenudation is restricted to chemical weathering in humid climates, while diastrophism is restricted to river erosion in arid climates.
BDenudation covers exogenic weathering, mass wasting, erosion and transportation, whereas diastrophism covers crustal movements such as orogeny, epeirogeny, earthquakes and plate tectonics.
CDenudation includes only deposition, while diastrophism includes only volcanic eruptions and intrusive forms.
DDenudation is an internal land-building process, while diastrophism is the solar-energy-driven wearing down of relief.
15In geography, the term 'insolation' refers to which of the following?
AIncoming solar radiation received by the Earth
BHeat released by the Earth as long-wave radiation
CThe daily range between maximum and minimum temperature
DThe pressure exerted by the atmosphere at sea level
