THere are many rock formations of different materials and ages. The Piedmont is the remains of several old mountain chains. Geologists say at least five separate events led to sediment being depositted. These include the Grenville orogeny and the Appalachian orogeny. The last major event in the history of the Piedmont was the break-up of Pangaea. This was when North America and Africa began to separate. 
Soils and farming.
Piedmont soils are generally clay-like (Ultisols). They are moderately fertile. In some areas, they have suffered from erosion . They have also been farmed heavily. This is mostly in the South where cotton was the main crop. In the central Piedmont region of North Carolina and Virginia, tobacco is the main crop. In the north region, the land is used for many different things. These include orchards, dairying, and general farming.
