Why do E horizons not occur everywhere?
What will be an ideal response?
The E horizon is a nearly white horizon defined by an absence of organic matter, clay, oxide and hydroxide minerals, or easily weathered minerals present in the parent material. E horizons form when weathering reactions dissolve soluble chemical components and flush the dissolved chemicals downward and when all solid weathering products (clay, oxide and hydroxide minerals) are flushed downward as well. E horizons contain only highly weathering-resistant minerals such as quartz. The process that forms an E horizon requires a considerable flux (throughput) of water and lots of reactive organic acids. These requirements are only met in humid forests, because they have the necessary high rainfall and organic material.
