Answer:
Pedalfer soils would most likely be found in the eastern half of United States
Step-by-step explanation:
The climate in the eastern half of the US is humid and rainy. When leaves of trees fall off during an extreme rainfall event, leaves mix up with soil to produce padalfer soil. The word padalfer is based on the two elements is (aluminum and ferrous) that are commonly present in this soil type. These elements join the soil because of these biogeochemical cycles. This is also the reason that the word "padalfer", contains Al and Fe.
