1. Spodosols
2. Alfisols
3. Aridisoils
4. Vertisols

Answer 1

Correct Answer - Option 2 : Alfisols

The correct answer is Option(2) i.e. Alfisols.

• Types of Soil(North America): 
  • The current system of soil classification, called soil taxonomy, involves hierarchical groupings of soils based on strictly defined types of horizons, temperature, color, drainage or wetness, chemistry, and mineralogy.
• The following tables show the types of soils with respective features.

  TYPES OF SOIL	FEATURES
  Spodosols	The temperate zone with a cool climate is characterized by spodosols. It forms on sandy items of mixed coniferous & deciduous forests.
