The correct answer is option 2, Laterite Soil. Laterite soil is commonly found in Kerala and is characteristic of tropical regions. It is formed by the leaching process, which washes away the soluble nutrients from the soil and leaves behind iron and aluminum oxides. This soil type is often red or reddish-brown in color due to the presence of iron.
Option 1, Alluvial Soil, refers to soil deposited by rivers and is not typically found in Kerala. Option 3, Sandy Soil, refers to soil with a high proportion of sand particles and is also not abundantly found in Kerala. Option 4, Loamy Soil, is a mixture of sand, silt, and clay and while Kerala may have some areas with loamy soil, it is not the dominant soil type in the region.
