Prologue
- Geography series by Dr.Kevin Virani, Faculty SPIPA
- Videos not available but PDFs of the powerpoints themselves cover all the descriptions
- Language: English
- Utility: Geography for UPSC Civil Services General Studies Paper, CAPF, CDS and similar competitive exams.
- Following topics are covered in the PDF file given at the bottom of this article
Geomorphic Process
- Exogenetic forces : LAND WEARING forces : weathering, mass movement, erosion, deposition
- Endogenetic forces : LAND BUILDING forces : diastrophism and volcanism
- Geomorphic agent : gravity
- What is Diastrophism? And its types?
- Epeirogenic movements? Two types : 1)Upward 2)downward
- Orogenic movements? = Mountain building movements
- Two types : 1)Compressional forces 2) Tensional forces
- Extra : 2001 Gujarat earthquake > fault developed
- What is Folding and faulting?
- Types of fold
- What is Anticlines? What is Synclines?
- Symmetrical fold, Asymmetrical fold, Monoclinal fold, Isoclinal fold, Over fold, Recumbent fold, Over thrust /what is a NAPPE fold?, fan folds
- Types of fault :Normal fault, reverse fault, thrust fault, lateral fault, step-fault
- What is the importance of faults?Also explain the Several landforms formed due to faults .
- What is a rift valley?
- Difference between rift valley and ramp valley – its examples
- What is a block mountain?
- Difference between block mountain and horst mountain
- What is an Escarpment? Fault scarp
Landforms- Types of
- Classify landscapes by scale – THREE ORDERs of RELIEF: first order relief , second order relief, Third order relief
- landforms : three types : mountain, plateau and plains
- Types of mountain. Explain :Fold mountain, block mountain, residual mountain and volcanic mountain
- State the Characteristics of Fold mountains
- Map work : Fold mountains of the world – List of mountains to locate
- Importance of mountain building process. Block mountains formation and its examples, Residual mountain formation and its examples.
- Explain the types of Volcanic mountains.
- General terms: Mountain ranges, Mountain chain, Mountain system, Mountain groups and what is Cordillera?
- Types of plateaus : Intermontane plateau, Piedmont plateaux, Dome shaped plateaux, Continental plateaux and Volcanic plateaues
- Examples of plateaus of the world – Bolivia plateau, Tibetan plateau, Anatolia plateau, Katanga plateau, Columbia-snake plt (USA), Deccan Plateau, Shan plateau (Myanmar)
- Plains – features -Types of Plains :Diastrophic plains, Peneplains, Glacial plains, Karst plains, alluvial plains and its examples.Loess plains, Lava plains.
Weathering: Exogenic process
- Exogenetic Movements: What is denudation? Explain Denudational process and their driving forces
- What is weathering?
- What are the Differences between weathering and erosion
- Types of Weathering – physical, chemical and biological
- Chemical Weathering Processes
- solution, carbonation, hydration, oxidation and Reduction
- Why are clay minerals easily erodible?
- Biological activity and weathering
- Physical Weathering Processes, Forces affecting physical weathering , Unloading and Expansion – exfoliation domes, Temperature Changes and Expansion – tors
- What is the difference between exfoliation domes and exfoliated tors?
- Freezing, Thawing and Frost Wedging
- Salt Weathering
- Block Separation and shattering
- What is the significance of weathering?
Mass Movements
- three major types of mass movements : Slow movements; (ii) rapid movements; (iii) landslides.
- Slow mass Movements:Creep – soil creep, rock creep, talus creep and glacier creep, Solifluction
- Rapid Movements :Earthflow, Slump, Mudflow, Debris avalanche
- Explain the types of Landslides :Debris slide and debris fall, Rock slide and rock fall
- Bring out the causes for more frequent landslides in the Himalayas than in Western Ghats – UPSC mains 2013
- SOIL FORMATION.Explain : Process of Soil Formation , Soil-forming Factors
- What is erosion? ,Abrasion, attrition, corrosion, plucking and deflation.
- Agents of gradation :running water – river, Ground water, Sea water, Glaciers,winds
- Agents of gradation form two types of landforms :Erosional landforms, Depositional landforms
- Fluvial landforms –
- River course – youth, mature and old stage of river course
- What is head ward erosion?
- Fluvial Erosional Landforms: River Valley Formation – how V shaped valleys form?, Gorge vs. canyon.Waterfalls and rapids ,Pot Holes, Plunge pools ,Terraces,Gulleys/Rills, Peneplain, Fluvial Depositional Landforms ,Alluvial fans
- Deltas – types of deltas
- What is an Estuary? And what is a delta?
- Flood plains
- Natural levees and point bars
- Meanders – Actually not a landform but a type of channel pattern
- Incised or entrenched meanders
- Braided channels
- Explain the Karst – Erosional Landforms :Prerequisites for the ground water to be effective ;Sinkholes / swallow holes ,Collapse sinks = Dolines, Valley sink = uvalas ,Lapies , Caves formation
- Karst – DEPOSITIONAL Landforms:Stalactites, Stalagmites, Columns
Glacier Landforms
- What is a glacier? Types of glacier.
- Continental or piedmont glacier
- General terms : snowline, ice-cap, ice-sheets, ice-bers
- Glacier erosional Landforms: Cirque and cirque lake, Horns and Serrated ridges ,Arêtes ,Glacial valleys / troughs ,Hanging valley
- Glacier depositional Landforms: Glacial till, Outwash deposits and plains, Moraines ,Terminal, lateral and ground moraines,esker,drumlins, Nunatak, roche moutonne
Land forms by Sea water
- Two types of coast :High-rocky coast (submerged coast); Low-smooth-gently sloping sedimentary coasts(emerged coast)
- Why does the west coast of India have more ports than the east coast?
- High rocky coasts
- Low sedimentary coasts
- Erosional landforms
- Wave-cut cliffs and terraces
- sea caves and Sea-stacks
- Depositional Landforms:Beach and dunes, Shingle beaches, Bars,barriers and spits – barrier bar, Looped bar,connecting bar and tombolo, Map work : Hope Island (India)
Land forms by wind
- Erosional landforms by wind :Pediments and Pediplains, an inselberg, Comparison : piedmont Vs. pediment, Playas, Bajada, deflation hallows and caves, Mushroom, Table and Pedestal Rocks ,Zeugen, Yardang, Dreikanter, Mesa, Stone lattice.
- Depositional Landforms by wind:Sand dunes, Barchans,Parabolic dunes , Seif, Longitudinal dunes, Transverse dunes,Loess plains.
