Explored Orinoco & established its connection with Amazon. Explored virgin lands of Siberia. In his ‘Relation Historique’ he laid down the foundation of plant geography. Divided regions of Latin America into botanical provinces. His “Kosmos” talked about universe & geographical thought since Egyptians. Believed in empirical, comparative & inductive method.

6. Carl Ritter (1779-1859 AD) - Was a teleologist. Gave the concept of “Unity in Diversity”. Stressed on land & water hemispheres, distinction between the rates of cooling of land & water. Defined geography as empirical science rather than deductive. Was a professor at university of Frankfurt & Berlin & founded the “Berlin Geographical Society”. He rejected the idea of ‘Pure Geography’(Reine
Geography) & said that history & geography must always remain inseparable. Chiefly concerned with the studies of human geography. Identified each continent with a different race. He was an armchair geographer. Wrote “Erdkunde” meaning science of the earth. Asia & Africa covered but
not Europe.

Analysis of Rocks


1. Cuestas or Homoclinal Ridge, physical feature that has a steep cliff or escarpment on one side and a
gentle dip or back slope on the other. This landform occurs in areas of tilted strata and is caused by the
differential weathering and erosion of the hard capping layer and the soft underlying cliff maker, which
erodes more rapidly. Cuestas with dip slopes of 40°–45° are usually called hogback ridges. A mesa is an elevated area of land with a flat top and sides that are usually steep cliffs.

2. A sandur (plural sandar) is a plain formed by meltwater from glaciers. Sandar are usually wider than their length, and consist of soft sediments, which are criss-crossed by braided streams of meltwater.

3. Regolith is a layer of loose, heterogeneous material covering solid rock. Peridotite, igneous rock
composed of pyroxene, olivine, and hornblende. It is the rock that makes up the earth's mantle. Very
sudden cooling of volcanic magma results in formation of volcanic glass called obsidian. The extrusive
equivalent of granite is rhyolite & gabbro is the intrusive equivalent of basalt.


4. Entrenched & intrenched meanders are one & the same & it is ingrown meanders which grow on
assymetric valley.

5. Tephra & pyroclastic material are the same & refer collectively to volcanic materials.

6. A glacier with a negative budget is a receding glacier & that with positive budget is advancing.

7. Rectangular inselbergs are called koppie or kopje.

8. Gloup is a blow hole, where a chimney has developed behind the cliff face, often above a cave, and spray is blasted out during high seas.

9. In a braided stream, the main channel divides into a number of smaller, interlocking or braided channels. Streams with high sediment loads that encounter a sudden reduction in flow velocity generally have a braided channel type.

10. Rise of land or fall of sea level is called negative movement & is connected with rejuvenation.

11. Jura mountains were formed during Mesozoic period.

12. Researchers now recognize five glaciations in the Quaternary period: Donau, Gunz, Mindel, Riss and Wurm (in that order from old to new). Their names derive from water courses in the North Slope of the Alps. These glaciations are included in the first period of the Quaternary: the Pleistocene. The second period of the Quaternary, the Holocene, starts at the end of the last glaciation (Wurm), about 10 thousand years ago. Mindel falls under middle Pleistocene.

13. Solifluction is the slow downslope flow of soil and sediment that is saturated with water

14. Both P waves & S waves (shear, transverse) are collectively called body waves. While Surface waves include Rayleigh waves (vertical and longitudinal) & Love waves (transverse horizontal).

15. A strike slip fault is also known as wrench fault. The scientific study of rivers is called Potamology. Colluvium is the loose deposits of rock, usually located at the foot of a slope or cliff, having been brought there under the influence of gravity (mass wasting). Talus includes angular fragments of rock below cliffs and steep slopes. Colluvium includes slope wash.

16. Evidences of earliest known life have been found to archaeozoic period.

17. Victoria fall is due to faulting. Livingstone fall is at the edge of a plateau. Yosemite fall is a hanging
valley & Niagara fall is due to alternate bands of resistant & soft rocks.

18. Reg is a surface covering of coarse gravel, pebbles from which all sand and dust have been removed by wind and water.

19. Billow clouds are created when different layers of wind flow at different velocities resulting in unstable turbulence between the layers. The common name for this instability is Kelvin-Helmholtz instability. Billow clouds provide a visible signal to pilots of potentially dangerous turbulence.

Biogeography


1. Field capacity refers to 50 % water & 50 % air. Leaching produces increasingly acidic & mineral deficient soil. Laterization (now called Ferralization) occurs in humid tropics where heavy rain & uninterrupted warmth give rise to a deeply weathered layer. Melanization refers to darkening of soil profile while Leuciniation refers to lightening of the colour both in A horizon. Induration refers to hardening of soil & Audification refers to the accumulation of H ions mainly in surface horizons.

2. The surface horizon is usually referred to as the O layer; it consists of loose organic matter such as fallen leaves and other biomass. O horizon is further divided into 3 sub horizons. The layer of plant material on the soil surface is classified as: the L horizon (fresh litter); the F horizon (decomposing litter); the H horizon (well decomposed litter)

3. Below that is the A horizon, containing a mixture of inorganic mineral materials and organic matter.
Next is the E horizon, a layer from which clay, iron, and aluminum oxides have been lost by a process
known as leaching (when water carries materials in solution down from one soil level to another). Removal of materials in this manner is known as eluviation, the process that gives the E horizon its name. Below E horizon is the B horizon, in which most of the iron, clays, and other leached materials have accumulated. The influx of such materials is called illuviation. Under that layer is the C horizon, consisting of partially weather bedrock, and last, the R horizon of hard bedrock. Hence the horizons are
L, F, H, A, E, B, C & R from top to bottom.

of the world is around 300 gm/sq.m/year.

7. 15 lakh species of animals & 2.5 lakh plant species on earth. Out of which 75 thousand animal & 15
thousand plant species are found in India.

8. The most commonly used Freon is Freon-12, or dichlorodifluoromethane (CCl2F2). Freon-11 is
Trichlorofluoromethane (CCl3F).

9. Solonchak soils are defined by high soluble salt accumulation & formed from saline parent material under conditions of high evaporation. Pedocals are soils of arid regions and are characterized by calcite (CaCO3) cementation due to upward movement of water (evaporation). Pedalfers are soils of humid regions and are characterized by highly leached clays due to downward movement of water. Extreme pedalfers are called laterites.

10. Ferrous group includes iron, chromite, manganese, & nickel. Non-Ferrous group has copper, lead, zinc, tungsten, aluminium, vanadium etc.

11. The largest number of sheeps & goats are both in China.

12. Coal, Petroleum & electricity are respectively known as black, liquid & white gold.

21. Apiculture refers to rearing of honey bees. Silviculture refers to growing & tending of trees as a branch of forestry. Connate water (also called fossil water) refers to water trapped in the interstices of rocks during their formation. Phenology is the study of seasonal changes upon animal & plant life.

22. Hall Herault process is used in the extraction of Aluminium from its ore.

23. South China sea is the largest sea.

Oceanography:


1. The Peru-Chile trench is the longest in the world. The only difference between ridge & rises is that ridges are steep sided while rises are gently sloped.

2. Juan de Fuca Strait, is the arm of the Pacific Ocean between Washington & Vancouver.

3. Thermocline is the transition layer between the mixed layer at the surface and the deep water. The various salts in the sea in order of decreasing quantity are NaCl, MgCl, MgSO4, CaSO4.

4. Danube, Dneiper, & Dneister all fall into black sea reducing it salinity.

5. Water moves from areas over which there is a low pressure to areas over which there is a high pressure.

6. The pelagic zone includes those waters further from the land, basically the open ocean. It is divided into neritic zone (having a depth of 200metres) & the oceanic province (separated from the neritic province by the edge of the continental shelf). The benthic zone refers to the sea bottom itself & is divided into littoral zone & deep sea zone. The two zones have their frontier at a depth of 200 meters. Benthos (plants such as kelp, sponges) are organisms that live on the ocean floor while nektons are swimming animals such as fishes & whales.

7. The east pacific rise is known as albatross plateau extending from north of New Zealand to the Californian coast.

8. Oozes are pelagic deposit in the form of liquid mud. There are divided on the basis of content into
calcareous ooze (lime) & siliceous ooze (silica). Calcareous ooze is further divided into pteropod ooze & globigerina (most widespread) ooze. Siliceous ooze is divided into radiolarian (formed of shells of
foraminifera) & diatom ooze.

9. Red clay is the most widely spread pelagic deposit & consists mainly of hydrated silicate of Aluminium & oxides of iron. Neritic deposits consists of dead shells of plants & animals.

10. Atlantic Ocean: The warm North Atlantic Drift (NAD) gives rise to the Irminger Current south of Iceland which travels along western and northwestern coasts of Iceland until it meets East Greenland Current. Another branch of NAD flows along Norway coast forming Norwegian current. Falkland current brings the cold waters of the Antarctic sea northward up to Argentina.

11. Pacific Ocean :Kuroshio (or Kuro Siwo) Current of Pacific is similar to the gulf stream of Atlantic. One branch separates from Kuroshio current & enters the sea of Japan as Tsushima current. The Cold Oyashio (or Oya Siwo) Current (similar to Labrador current) is also known as Kurile current & it flows through the Bering Strait in a southerly direction. The cold Okhotsk current flows past Sakhalin to merge with Oya Siwo current near Hokkaido Island & later mergers with the warm Kuro Siwo current producing dense fogs. The north pacific drift continues later as Aleutian current which divides into two parts – the northern branch becomes Alaska current while the southern branch becomes California cold current (similar to Canary cold current of Atlantic). Cromwell current also called pacific equatorial undercurrent is a submarine river & flows towards east. Mindanao current is a southward flowing boundary current along the Philippine coast.

12. Indian Ocean: One branch of the south equatorial current moves southward through the Mozambique Channel to form the Mozambique Current. This current joins the Agulhas Current & moves to the southern tip of Africa. During the northeast monsoon season the Somali Current flows southward & During the southwest monsoon the current develops into an intense northward jet

13. La Nina is opposite of El Nino & intensifies the Humboldt Current. El Nino causes drought conditions in India, Southern Africa, Australia & heavy rains in Chile, Colorado. The El Nino events of 1982 & 1997 were severe. The Southern Oscillation, a more recent discovery, refers to an oscillation in the surface pressure (atmospheric mass) between the southeastern tropical Pacific and the Australian-Indonesian regions

Climatology


1. ‘Mother of pearl’ or ‘nacreous’ clouds are found in stratosphere. Noctiluent clouds are found in Mesosphere.

Division of Ionosphere (60-640 Km)
1. D layer- 60-. Km -Reflects signals of low frequency radio waves only. Disappears with sunset.
2. E layer -99-130 km- Called Kenley- Heaviside layer. Reflects medium & high frequency radio waves. Produced by ultraviolet photons reacting with nitrogen. Disappears with sunset.
3. Sporadic E Layer -110 km- Associated with very high velocity winds & created under special circumstances. Reflects VHF waves
4. E2 layer- 150 km- Produced by reaction of UV photons with O2. Disappears with night.
5. F Layer -1550-380 km- Consists of F1 & F2 layers collectively called Appleton layer. Reflects medium & high frequency radio waves.
6. G layer 400 km & above Persists day & night but not detectable as F layer reflects all the waves reflected by this layer. Interaction of UV photon with nitrogen produces free electrons here.

2. The auroras are maximum when the sun is very active. Hence they are opposite of sun spot cycle. Inside the magnetosphere are the Van Allen radiation belts concentrated in two bands at about 3000 km & 16000 km.

3. According to Wein’s displacement law, hotter the object smaller the wavelength. According to
Stefan Boltzman law influx of radiation is proportional to the fourth power of absolute temperature
of the radiating body.

4. Heat Budget: Out of the 100 units of incoming solar radiation, 35 units (27-clouds, 2-snow, 6 atmosphere top) are reflected back as albedo. Out of the remaining 65 units, 14 units are absorbed by atmosphere & 51 units by earth surface. The earth radiates back 17 units directly into space & remaining 34 units are absorbed by atmosphere. The atmosphere than radiates back the 48 units absorbed by it.

5. Green house gases include CFCs, Nitrous oxide, water vapour & ozone. CFCs account for 25 % of
green house effect & methane for 15 %. Carbon dioxide leads with 55 %.

6. The greatest range of temperature occurs at latitude 60 N.

7. The major types of inversion are: radiation, air drainage, frontal, advection, subsidence. Advection inversion generally occurs when a warm air passes over cold water surface.

8. Highs are Siberian, Hawaiian & Siberian. Lows are Aleutian & Icelandic.

9. Anemometer is used for measuring the speed of wind. Beaufort scale deals with the wind speed & ranges from calm wind to hurricane.

10. Jet streams are fastest during winter season. They blow from west to east.

11. A mist becomes a fog when visibility is reduced to less than a km. Dry adiabatic rate is 10 C per 1000m & moist adiabatic rate is 6 C per 1000m. Stability occurs when the dry adiabatic rate is higher than the normal lapse rate & instability occurs when normal lapse rate is greater than the dry adiabatic lapse rate. If normal lapse rate is lower than wet adiabatic rate it leads to absolute stability & vice versa.

12. Sleet is partially melted snowflakes while hail refers to small balls of ice. Rime refers to very small super cooled droplets which strike ground & tend to freeze immediately on impact.

13. Four principal forms of airmasses are continental polar (cP), maritime polar (mP), continental tropical (cT), and maritime tropical (mT). Thermodynamic modification results in airmasses becoming warm represented by W or cold (K). Mechanical or dynamic modification causes it to become stable (s) or unstable (u).

14. Baroclinic zone is where distinct air mass regions exist & where Fronts separate warmer from colder air. Barotropic is region of uniform temperature distribution with lack of fronts. Temperate cyclones are formed under baroclinic condition & tropical under barotropic condition.

15. Anticyclones are larger than cyclones. Airflow converges aloft in anticyclones & diverges in case of cyclones. Katabatic wind blows from mountains to valley & anabatic vice versa.

WORLD GEOGRAPHY FACTS - II


1. Davisian cycle ends in peneplain, Penck’s in endrumpf & kings in pediplain. Kings cycle basically deals with the evolution of landforms in arid & savanna regions.

2. Penck cycle has three stages. Aufsteigende Entwickelung means a phase of waxing (accelerating) rate of landform development where the slopes of the valley sides are convex in plan. Gleichformige Entwickelung means uniform development of landforms. Absteigende Entwickelung means wanning development & parallel retreat of slope continues

3. Boschungen is the upper steep part & haldenhang is the lower part with lesser inclination. Thus the
intersection of boschungen & haldenhang produce a sharp knick. Ultimately the boschungen are reduced to inselbergs.

4. Monadnocks are also known as unakas & mosores.

5. Sinkholes < Swallow Holes < Dolines <Jamas < Uvala < Polje. All these karst landforms are differentiated just on the basis of size. Uvala results from subsidence of large roof over underground
courses. Ponores are vertical pipelike passages that connect caves & swallow holes. Hums are residual
hills analogous to monadnocks in fully developed karst topography. Lappies are bare terra rosa having
crevasse like pinnacle structure formed where relief is considerable.

6. Speleothems is the term collectively used for all types of deposits in caverns. Dripstones growing
sidewards from stalactites & stalagmites are called helectites & helegmites. Helectites of globular structure are called globulites & banded calcareous deposits are called tavernites.


7. Longshore Drift is movement of sand parallel to the shoreline, in the “along-the-shore” direction. The
process arises when waves approach the shore obliquely. The swash moves the sediment particles up the beach at this angle, while the backwash brings them away fom the beach. This has the net effect of gradual movement of the particles along the shore.

8. Notch is formed as a depression at the base of a cliff due to wave attack. Blowholes formed at roof tops sometimes enlarge & cause the roof top to fall forming Geos or inlets.

9. Big sand bars usually parallel to the beach are called offshore or longshore bar. If the bars are formed such that there one end is attached to the beach & the other end is projecting into the sea, they are called spits. Hooks are curved spits & a bar connecting two land masses is a Tombolo.

10. Old man of Hoy is the most famous wave cut stack located in Orkney Islands, North Scotland.

11. Rias (ria coast) is form when sea levels rise or plate tectonics cause coastal levels to fall. When this
happens valleys which were previously at sea level become submerged. The result is often a very large
estuary at the mouth of a relatively insignificant river.

12. Dalmatian coast are found in Italy & Dalmatian area of Croatia where ranges are parallel to coast

13. Gulf of Aqaba, northeastern arm of the Red Sea, separating the Sinai and Arabian peninsulas.

14. Negev Desert is in Israel.

15. Pedestal or Mushroom rock is also known as Gour in Sahara & pilzfelsen in Germany.

16. Inselbergs or Bornhardts are isolated hills rising abruptly from virtually level plain. Demoiselles have
resistant rock cap at the top. Zeugens have horizontal rock strata & yardangs have vertical. Ventifact with a single face is called einkanter, zweikanter (2 faces) & driekanter (3 faces).

17. Areas of shifting sand-dunes is called erg. Barchans are also known as transverse dunes.

18. Glacial loess of N. America is called adobe & that of Europe is called limon

19. When a basin is more or less rimmed by mountain (inter-montane basin), it is called a bolson. The basin is characterized by centripetal drainage which leads to formation of salty lakes called playas in N. America, “Shatts” in Sahara, ‘Mamlaha’ & ‘Khabari’ in the Arabian desert.

20. The whole slope between the mountains to the playas is called pediment.

21. When two cirques converge cutting back it is called col. A cirque lake is called tarn. Paternoster lakes are formed at the foot of glacial stairways. A nunatak is a mountain top that is not covered by land ice, and protrudes out of a surrounding glacier. Roches moutonnees is a residual rock hummock whose upstream is smoothened by abrasion & downstream is roughened by plucking. Riegel marks the outcrop of a highly resistant rock layer. They have plucked downside.

22. Eskers or Osser or Oss is a stratified deposit. If the ice front halts at regular intervals, beaded eskers are formed. Kames are small hills which are deposited by meltwater near or at the edge of the retreating ice sheets.


23. Kettles are depressions in the outwash plain. Large kettles are clotted with numerous low mounds called hummocks. Drumlins are elongated hummocks of boulder clay (basket of egg).

24. Protalus rampart is the accumulation of debris formed due to rockfall from the cliff.

25. Varve is the yearly deposit of sediment forming distinctive layers. It is most frequently used to refer to deposits formed in lakes on the margins of glaciers.

26. Pingos are ice mounds formed due freeze thaw action in periglacial environment. Palsas are low
permafrost mounds with cores of layered segregated ice and peat, similar to a pingo. Talik refers to an
unfrozen section of ground found above, below, or within a layer of discontinuous permafrost. Tors
are piles of rock on the top & clitters on the sides formed due to congelifraction

27. Borneo is the 3rd largest island in the world after Greenland & New Guinea.
