Which one of the following is a example of Pedalfer soil ?

Question

Accepted Answer

Laterite soil is an example of Pedalfer soil.

Here's why:

*   **Laterite:** Laterite soils are rich in iron and aluminum oxides, which are characteristic of Pedalfer soils. Pedalfer soils are generally found in humid, temperate climates where leaching is significant. The leaching process removes soluble minerals, leaving behind the less soluble iron and aluminum oxides, giving laterite its reddish color and characteristic composition.

Here's why the other options are incorrect:

*   **Black (e.g., Chernozem):** Black soils, such as Chernozems, are typically associated with grassland environments and are characterized by a high organic matter content. They are not primarily defined by the accumulation of iron and aluminum oxides like Pedalfer soils. They are more closely associated with Pedocal soils.

*   **Alluvial:** Alluvial soils are formed by the deposition of sediments carried by rivers and streams. Their composition varies depending on the source material and depositional environment. While they can contain iron and aluminum, their defining characteristic is their depositional origin, not the specific accumulation of oxides that defines Pedalfer soils.

*   **Rendzina:** Rendzina soils are shallow, dark soils that develop over calcareous bedrock (like limestone). They are characterized by a high calcium carbonate content and are not associated with the accumulation of iron and aluminum oxides that define Pedalfer soils.
