   • A.Gully Erosion
   • B.Rill Erosion
   • C.Sheet Erosion✓ Correct Answer
   • D.Stream Bank Erosion

    • A.Wheat
    • B.Cotton
    • C.Cashew Nut✓ Correct Answer
    • D.Maize

    Explanation: Laterite soils are acidic and rich in iron; they are suitable for plantation crops like Cashew nuts, Tea, and Coffee with proper manure.

    • A.Alluvial Soil✓ Correct Answer
    • B.Podzol
    • C.Chernozem
    • D.Laterite

    Explanation: Azonal soils are immature soils without well-developed horizons, such as Alluvial soil (transported by rivers) or Lithosols.

13. Q13.The term 'Maquis' refers to:

    • A.A type of soil in Russia
    • B.Scrub vegetation in the Mediterranean✓ Correct Answer
    • C.A tropical grassland
    • D.Frozen subsoil

    Explanation: Maquis is a dense scrub vegetation found in the Mediterranean region, typically consisting of drought-resistant shrubs.

14. Q14.Peat soil is characterized by being:

    • A.Low in organic matter
    • B.Rich in organic matter and wet✓ Correct Answer
    • C.Sandy and dry
    • D.Rich in calcium

    Explanation: Peat soils form in waterlogged conditions (bogs/marshes) where organic matter accumulation exceeds decomposition.

15. Q15.Which vertical zone of vegetation is found at the highest altitude in mountainous regions?

    • A.Deciduous Forest
    • B.Coniferous Forest
    • C.Alpine Meadow✓ Correct Answer
    • D.Tropical Forest

    Explanation: As altitude increases, vegetation changes. Alpine meadows occur above the tree line, just below the snow line.

16. Q16.The process of 'Capillary Action' typically leads to the formation of which soil type in dry regions?

    • A.Saline/Alkaline Soil✓ Correct Answer
    • B.Acidic Soil
    • C.Peaty Soil
    • D.Glacial Soil

    Explanation: In dry climates, evaporation pulls groundwater upward carrying dissolved salts, which remain on the surface (Salinization).

17. Q17.Which of the following is a characteristic feature of Xerophytic vegetation?

    • A.Large broad leaves
    • B.Deep roots and waxy leaves✓ Correct Answer
    • C.Breathing roots
    • D.Thin bark

    Explanation: Xerophytes (desert plants) have adaptations like deep roots to find water and waxy/spiny leaves to reduce water loss.

    • A.Amazon
    • B.Orinoco✓ Correct Answer
    • C.Parana
    • D.Nile

    • B.It is too sandy
    • C.It is too rocky
    • D.It has too much water

    Explanation: Red soils are often leached and deficient in essential nutrients like nitrogen, humus, and phosphorus.

    • B.Tundra Biome
    • C.Desert Biome
    • D.Rainforest Biome

    Explanation: The Savanna biome is often described as 'Parkland' due to its open canopy of scattered trees amidst continuous grass.
