- A.
Latosols
- B.
Podsols
- C.
Sandy soils
- D.
Clayey soils
Correct Answer
A. LatosolsExplanation
Latosols are the correct answer because they are commonly found in tropical rainforests. Latosols, also known as laterite soils, are typically reddish or yellowish in color and are formed in areas with high temperatures and heavy rainfall. These soils are highly weathered and contain a high concentration of iron and aluminum oxides. They have a low fertility due to leaching of nutrients, but their high clay content allows them to retain water well. Latosols are well-suited for supporting the diverse vegetation found in tropical rainforests.Rate this question:
