1Weathering differs from erosion primarily in that weathering:

A.Breaks down rocks in place without necessarily removing them

B.Transports rock debris to a new location

C.Is caused only by flowing water

D.Occurs only below the water table

Explanation: Weathering is the in-situ physical and chemical breakdown of rocks at or near Earth's surface. Erosion involves the removal and transport of weathered material by agents such as water, wind, ice, or gravity. The two processes often work together but are conceptually distinct.

2Frost wedging is an example of which type of weathering?

A.Chemical weathering

B.Physical (mechanical) weathering

C.Biological weathering only

D.Solution weathering

Explanation: Frost wedging occurs when water freezes in cracks, expands by about 9%, and pries rock apart. It is a classic form of physical (mechanical) weathering because the rock's chemistry is not primarily changed—only its mechanical integrity.

3According to plate tectonic theory, new oceanic crust is primarily generated at:

A.Transform faults

B.Deep-sea trenches by subduction

C.Mid-ocean ridges (divergent boundaries)

D.Continental collision zones

Explanation: At mid-ocean ridges, plates diverge and upwelling mantle melts produce basaltic magma that solidifies as new oceanic crust. Seafloor spreading continuously adds crust at these divergent boundaries while older crust is consumed at subduction zones.

4The Himalayan mountain belt is the classic product of which plate-boundary type?

A.Ocean–ocean convergent boundary

B.Divergent mid-ocean ridge

C.Transform plate boundary

D.Continent–continent collision

Explanation: The Himalayas formed by the ongoing collision of the Indian plate with the Eurasian plate after the Tethys Ocean closed. Continent–continent collision produces intense crustal shortening, thick orogenic crust, and high topography without a typical oceanic trench.

5The focus (hypocentre) of an earthquake is best defined as:

A.The underground point where rupture begins

B.The point on Earth's surface directly above the rupture origin

C.The farthest station that records the event

D.The centre of the Earth

Explanation: The focus or hypocentre is the subsurface location where seismic rupture initiates. The epicentre is the surface projection of that point. Depth of focus helps classify earthquakes as shallow, intermediate, or deep.

6P-waves differ from S-waves in that P-waves:

A.Travel only through solids and cannot enter liquids

B.Are compressional body waves that travel through solids and fluids

C.Are slower than S-waves in the same rock

D.Are surface waves with the largest amplitudes

Explanation: Primary (P) waves are compressional body waves that propagate through solids, liquids, and gases. Secondary (S) waves are shear waves that travel only through solids and are slower than P-waves. Surface waves arrive later and often cause strong shaking.

7The Mercalli intensity scale measures earthquake effects mainly in terms of:

A.Energy released at the focus in joules

B.Amplitude of P-waves on a seismograph only

C.Observed damage and human perception at a place

D.Depth of the hypocentre in kilometres

Explanation: The Modified Mercalli Intensity (MMI) scale ranks the severity of shaking and damage at a location from I to XII. Intensity varies with distance, local geology, and building quality. Magnitude scales (e.g., moment magnitude) estimate energy release at the source.

8A composite (stratovolcano) volcano is typically built of:

A.Only fluid basaltic lava flows with little ash

B.Only cinders ejected from a single brief eruption

C.Exclusively intrusive plutonic rocks

D.Alternating layers of lava and pyroclastic material

Explanation: Stratovolcanoes (composite cones) form from repeated eruptions of intermediate to felsic magmas, producing interlayered lava flows and pyroclastic deposits. Their steeper profiles contrast with broad shield volcanoes dominated by fluid basalt.

9In structural geology, the strike of a planar bed is best defined as:

A.The compass direction of the line of intersection of the bed with a horizontal plane

B.The angle of maximum inclination of the bed from horizontal

C.The thickness of the bed measured perpendicular to bedding

D.The direction of maximum compressional stress

Explanation: Strike is the azimuth of the line formed where a dipping plane intersects a horizontal plane. Dip is the maximum inclination of that plane measured perpendicular to strike. Together, strike and dip fully orient a planar structure.

10In an anticline, the oldest rocks are typically found:

A.In the outermost limbs

B.In the core (centre) of the fold

C.Only at the axial culmination of synclines

D.Randomly without relation to fold geometry

Explanation: An anticline is an upward-arching fold in which beds dip away from the hinge. By the principle of superposition in originally upright sequences, the oldest strata occupy the core. Synclines reverse this age pattern, with younger rocks in the core.

About the RBSE SS Geology Exam

Free English-language MCQ practice for Rajasthan RBSE Senior Secondary (Class 12) Geology (code 043), covering topics from official board syllabus scope and 2026 subject-wise result statistics. This bank is a study adaptation for concept practice — not an official paper simulation or practical substitute.

Exam sponsor: Board of Secondary Education, Rajasthan (RBSE), Ajmer. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Assessment

Official RBSE mixed written theory plus separate practical/viva components. Typical full marks pattern Theory 56 + Sessional 14 = 70 and Practical 30 = 100, theory duration 3 hours 15 minutes. Candidates must often pass theory and practical separately. Local bank: English-language four-option MCQ study adaptation — not a practical/performance simulation. Official delivery commonly English/Hindi. Subject code 043.

Time Limit

3 hours 15 minutes (theory); practical duration as per subject scheme (commonly ~3–4 hours)

Passing Score

Minimum 33% marks in the subject as per RBSE examination regulations (confirm current session circulars). Where theory and practical are separate, candidates must pass each component as required by the subject scheme.

Exam / Certification Fees

As per RBSE annual examination fee notification for school/private candidates (Senior Secondary (Class 12) full board form fee is notified each cycle on rajeduboard.rajasthan.gov.in — confirm the current circular; subject papers are not separately priced on the statistics page)
