RBSE SS Geology study guide
RBSE SS Geology · Work through your exam, one topic at a time.
The RBSE Senior Secondary Geology qualification is the Class 12 geology stream offered under the Rajasthan Board of Secondary Education (RBSE) framework. It suits students who want a science-flavoured senior secondary certificate with an earth-science focus, and it is typically taken by candidates preparing for university geology, mining, civil engineering or natural-resource careers. The RBSE SS Geology study guide has 9 sections and about 1,951 words.
01Physical Geology and Geomorphology
Physical Geology and Geomorphology examines the processes that shape the Earth's surface and the landforms they create. The exam tests endogenic versus exogenic processes, weathering and mass wasting, and landform recognition in fluvial, glacial, aeolian and coastal environments.
285 words, about 1 min02Crystallography and Mineralogy
Crystallography and Mineralogy covers the seven crystal systems, symmetry, Miller indices, and the physical properties used to identify minerals. The exam tests systematic mineralogy, silicate structures and Bowen's reaction series.
245 words, about 1 min03Petrology (Igneous, Sedimentary, Metamorphic)
Petrology tests the classification, texture, composition and origin of igneous, sedimentary and metamorphic rocks, and the processes that convert one type into another. Texture: phaneritic (coarse, intrusive), aphanitic (fine, extrusive), glassy, vesicular, pyroclastic.
203 words, about 1 min04Structural Geology and Tectonics
Structural Geology and Tectonics tests how rocks deform: strike and dip, folds, faults, joints, unconformities and plate-boundary tectonics. Strike is the compass direction of a horizontal line on a bedding plane; dip is the angle of steepest descent, measured perpendicular to strike.
239 words, about 1 min05Stratigraphy and Indian Geology
Stratigraphy and Indian Geology tests the principles used to order rock layers, the geological time scale, and the stratigraphic succession of India. Superposition: oldest at bottom in undeformed sequences.
200 words, about 1 min06Palaeontology and Historical Geology
Palaeontology and Historical Geology tests fossilisation, index fossils, major evolutionary events and the use of fossils for correlation and dating. Petrification (mineral replacement), moulds and casts, carbonisation, trace fossils, amber and ice preservation.
176 words, under 1 min07Economic Geology and Mineral Resources
Economic Geology and Mineral Resources tests ore-forming processes, Indian mineral deposits and the distinction between reserve and resource. Magmatic segregation: chromite, magnetite.
171 words, under 1 min08Applied Geology
Applied Geology tests how geological knowledge is used in engineering, groundwater, hazard assessment and exploration. Aquifer: porous and permeable; aquiclude: porous but impermeable; aquifuge: neither.
221 words, about 1 min09Field and Practical Skills
Field and Practical Skills tests geological mapping, compass-clinometer use, strike and dip measurement, sampling, hand-specimen identification and map reading. Brunton compass: measure strike, dip and dip direction; correct for magnetic declination.
