Answer 1

Answer:

D. i, iv

• Laterite soils are formed due to intense weathering of rocks under high temperature and heavy rainfall conditions.

• These soils are typically reddish or yellowish in color due to high iron oxide and aluminum oxide content.

Laterite soils are mainly found in regions with high rainfall, such as:

• Kerala

• Karnataka

• Odisha

• Assam

• Meghalaya

• West Bengal
  

Laterite soils are:

• Poor in nitrogen, phosphorus, and potassium

• Rich in iron and aluminum oxides

• Acidic in nature (low pH)

• Prone to erosion
  

Crops - Despite their poor fertility, laterite soils support crops like:

• Tapioca

• Cashew nuts

• Coconut

• Areca nut

• Spices like pepper and cardamom
