The Soil in a Rainforest

The soil of a tropical rainforest is only about 3-4 inches (7.8-10 cm) thick and is ancient. Thick clay lies underneath the soil. Once damaged, the soil of a tropical rainforest takes many years to recover. Temperate rainforests have soil that is richer in nutrients, relatively young and less prone to damage.
