The A horizon, the uppermost layer in the soil profile, often is called the surface soil. It is the part of the soil in which life is most abundant in such forms as plant roots, bacteria, fungi, and small animals. It is the part in which organic matter is most abundant. The B horizon lies immediately beneath the A horizon and often is called the subsoil. Lying between the A and C horizons, it utilizes the properties of both. Living organisms are fewer than in the A horizon but more abundant than in the C horizon. THE C horizon is the deepest of the three major horizons. It consists of the loose and partly decayed rock beneath the A and B horizons. The rock material in the C horizon is of the same kind which now forms the bulk of the soil above it.
Topsoil is another name for soil found in the A horizon. It is made up of minerals and is usually coarser and has less clay than the other horizons.
Continental crust is generally lighter than oceanic crust.
A soil horizon is a layer parallel to the soil surface, whose physical characteristics differ from the layers above and beneath. Each soil type has at least one, usually three or four horizons. Horizons are defined in most cases by obvious physical features, chiefly colour and texture. These may be described both in absolute terms (particle size distribution for texture, for instance) and in terms relative to the surrounding material, 'coarser' or 'sandier' than the horizons above and below.Horizon formation (horizonation) is a function of a range of geological, chemical, and biological processes and occurs over long time periods. Soils vary in the degree to which horizons are expressed. Relatively new deposits of soil parent material, such as alluvium, sand dunes, or volcanic ash, may have no horizon formation, or only the distinct layers of deposition. As age increases, horizons generally became more easily observed. The exception occurs in some older soils, with few horizons expressed in deeply weathered soils, such as the oxisols in tropical areas with high annual precipitation.
The question doesn't make sense. The horizon is created by the curvature of the Earth. When you are standing on a beach and view the horizion over the water, there is a definite line where the water seems to end. This is not because the water does end as they once thought, but because this is the point where the earth curves. On a larger planet the horizon would be much farther away. Thus the horizon is ever changing depending on your own location. He's talking about the soil horizons if you ever took earth science you would know. It is horizon A I am absolutely sure...
