Practice questions
Q1With reference to soil-forming processes, consider the following statements: 1. Laterisation under high temperature and heavy rainfall removes silica and bases and leaves iron-aluminium-rich material. 2. Calcification is associated with dry areas where calcium carbonate accumulates. 3. Podzolisation is associated with cool, humid and coniferous conditions in higher mountains. Which of the statements given above are correct? Select the correct answer using the code given below.
All three statements correctly connect a pedogenic process with its operating environment and result. Laterisation entails intense leaching in hot, wet conditions; calcification accumulates calcium carbonate in dry areas; and podzolisation develops under cool, humid coniferous conditions in higher mountains.
Q2Match List I with List II and select the correct answer using the code given below. List I (Soil) A. Laterite soil B. Sodic soil C. Peaty soil D. Black soil List II (Diagnostic process or management clue) 1. Gypsum may be used in reclamation 2. Heavy leaching in humid tropical conditions 3. Waterlogged and rich in organic matter 4. Swelling and shrinking clay
Laterite is linked with heavy leaching in humid tropical conditions. Gypsum can help reclaim sodium-dominated soils. Peaty soil is organic-rich and waterlogged, while black soil has clay that swells when wet and shrinks on drying. Thus the matching is A-2, B-1, C-3 and D-4.
Q3Arrange the following Himalayan vegetation formations in their general order from lower to higher altitude: 1. Alpine meadows 2. Tropical foothill forests 3. Coniferous forests 4. Temperate broadleaf forests Select the correct answer using the code given below.
With increasing altitude in the Himalaya, vegetation generally changes from tropical foothill forests to temperate broadleaf forests, then to coniferous forests and finally to alpine meadows. Hence the correct lower-to-higher sequence is 2-4-3-1.
Q4Consider the following statements about major Indian soils: 1. Black soil has high clay content, retains moisture and develops deep cracks in the dry season. 2. The red colour is associated with hydrated iron oxides, while the yellow colour comes mainly from iron compounds in crystalline rocks. 3. Laterite is a leached residual soil that can support plantation crops when rainfall and management are suitable. Which of the statements given above are correct? Select the correct answer using the code given below.
Statements 1 and 3 are correct. Black soil combines clay-rich texture, strong moisture retention and dry-season cracking. Laterite can support tea, coffee, rubber, cashew and other plantation crops under suitable rainfall and management. Statement 2 reverses the colour controls: iron compounds produce the red colour, whereas hydrated iron oxides are associated with yellow.
Q5Match List I with List II and select the correct answer using the code given below. List I (Species) A. Teak B. Sal C. Sundari D. Deodar List II (Vegetation association) 1. Sundarbans mangroves 2. Himalayan coniferous belt 3. Peninsular moist or dry deciduous belts 4. Moist deciduous belts of the Himalayan foothills and eastern-central India
Teak is an indicator of peninsular moist or dry deciduous belts; sal is associated with moist deciduous belts of the Himalayan foothills and eastern-central India; sundari is linked with the Sundarbans mangroves; and deodar indicates the Himalayan coniferous belt. The correct matching is A-3, B-4, C-1 and D-2.
