Quizplus · Accepted Answer

The B horizon is a soil layer where iron and aluminum often accumulate, leading to its lighter color compared to the A horizon above. The A horizon contains more organic matter, resulting in a darker color. The C horizon is the layer below the B horizon and consists of weathered parent material with little organic matter. The O horizon is made up of organic matter at the surface, while the E horizon is a relatively rare layer that occurs in some soils and is characterized by loss of minerals like iron and clay.
