  2. 2005 1 Bitumen is obtained from (A) Forests and Plants (B) Kerosene oil (C) Crude oil (D) Underground mines Answer C Bitumen is a mixture of dark, sticky, highly viscous organic liquids composed mainly of aromatic hydrocarbons. It is usually black or dark brown in color. Bitumen found in nature is known as crude bitumen, and that obtained by the distillation of crude oil is called refined bitumen. It is now possible to produce bitumen from non-petroleum based renewable resources such as sugar, molasses, or starch. Materials that contain bitumen are described as bituminous, such as bituminous coal and bituminous rock.

  3. 2. Malaria is caused by: (A) bacterial infection (B) viral infection (C) parasitic infection (D) fungal infection Answer C 3. The cloudy nights are warmer compared to clear nights (without clouds) during winter days. This is because: (A) clouds radiate heat towards the earth (B) clouds prevent cold wave from the sky, descend on earth (C) clouds prevent escaping of the heat radiation from the earth (D) clouds being at great heights from earth absorb heat from the sun and send towards the earth Answer C

  4. 4. Largest soil group of India is: (A) Red soil (B) Black soil (C) Sandy soil (D) Mountain soil soils Alluvial soil: Sand content decreases fromm west to east of the country New alluvium is termed as Khadar and old alluvium is termed as Bhangar. Colour: Light Grey to Ash Grey Texture: Sandy to silty loam or clay. Rich in: potash Poor in: phosphorous. Wheat, rice, maize, sugarcane, pulses, oilseed etc are cultivated mainly Major classification of Indian Alluvial soil [43%] Red soil [18.5%] Black / regur soil [15%] Arid / desert soil . Answer C . Laterite soil . Saline soil . Peaty marshy soil e Forest soil Sub-mountain sol Snowfields

  5. Red soil: Black soil / regur soil: Seen mainly in low rainfall area. Also known as Omnibus group. Porous, friable structure. Absence of lime, kankar (impure calcium carbonate) Deficient in: lime, phosphate, manganese, nitrogen, humus and potash. Colour: Red because of Ferric oxide. The lower layer is reddish yellow or yellow Texture: Sandy to clay and loamy. Wheat, cotton, pulses, tobacco, oilseeds, potato etc are cultivated Regur means cotton- best soil for cotton cultivation. Most of the Deccan is occupied by Black soil. Mature soil High water retaining capacity swells and will become sticky when wet and shrink when dried Self-ploughing is a characteristic of the black soil as it develops wide cracks when dried . . e Rich in: Iron, lime, calcium, potassium, aluminum and magnesiunm Deficient in: Nitrogen, Phosphorous and organic matter. Colour: Deep black to light black. . . . Texture: Clayey.

  6. Laterite soil: Name from Latin word Later, which means Brick Become so soft when wet and so hard when dried. In the areas of high temperature and high rainfall. . Forest soil: Regions of high rainfall. Humus content is less and thus the soil is acidic. . Formed as a result of high leaching. Lime and silica will be leached away from the soil. Organic matters of the soil will be removed fast by the bacteria as it is high temperature and humus will be taken quickly by the trees and other plants. Thus, humus content is low Rich in: Iron and Aluminum Deficient in: Nitrogen, Potash, Potassium, Lime, Humus Mountain soil: In the mountain regions of the country Immature soil with low humus and acidic. . . . Colour: Red colour due to iron oxide. Rice, Ragi, Sugarcane and Cashew nuts are cultivated mainly.

  7. Desert / arid soil: . Seen under Arid and Semi-Arid conditions Deposited mainly by wind activities. . High salt content. Peaty marshy soil: Areas of heavy rainfall and high humidity. Growth of vegetation is very less. A large quantity of dead organic matter/humus which makes the soil alkaline Lack of moisture and Humus. Kankar or Impure Calcium carbonate content is high which restricts the infiltration of water. . . Nitrogen is insufficient and Phosphate is normal. . Texture: Sandy Colour: Red to Brown. . Heavy soil with black colour.

  13. Answer A Rivers on the Indian peninsular plateau flow from West to East because of the gradient of the land. However, Narmada and Tapi flow in opposite direction because they do not flow on the plateau surface but in rift valleys and these valleys happen to have an opposite gradient. There are three main reasons: 1. Gradient of the terrain 2. Presence of rift valleys 3. Mountain ranges which deflect rivers. 5. Soils in the Mahanadi delta are less fertile than those in the Godavari delta because of: (A) erosion of top soils by annual floods (B) inundation of land by sea water (C) traditional agriculture practices (D) the derivation of alluvial soil from red-soil hinterland Answer A
