What are soil horizons?

What will be an ideal response?


Soil forms in layers. These layers lie parallel to the surface of the Earth. As layers are
added, they begin to take on different characteristics. These layers are called soil
horizons.

Determine the hexagonal close?packed lattice directions of the lines rt, ut, and uv in the figure for this problem. To do this, first determine the vector projection of a line in the basal plane and then add it to the c axis projection of the line. Note that the direction indices of the c axis are [0001], and that if [0001] is considered a vector its magnitude will equal the height    of the unit cell.    A unit distance along a diagonal axis of Type I, such as the distance or, equals one third of the length of [2110] in Fig. 1.20. The magnitude of this unit is thus equal to 1/3 [2110]. Combine these two quantities to obtain the direction indices of each of the lines.
