What will be an ideal response?
A typical soil profile consists of the O horizon, consisting of dead organic matter; the A horizon (top soil), consisting of a mixture of the mineral soil from below with the humus from above; the E horizon, consisting of a layer from which the minerals have been leached; the B horizon (subsoil), consisting of the layer to which the minerals leach from the A and E horizons; and the C horizon, consisting of the parent mineral material. The differences between each layer can sometimes be minor, but the size of particles is the main determinant.
