Rearrange the following soil orders from the least to the most highly weathered: Oxisols, Alfisols, Mollisols, Entisols, and Inceptisols.

Use the key given in Figure 8 to determine the soil order of a soil with the following characteristics: a spodic horizon at 30 cm depth, permafrost at 80 cm depth. Explain your choice of soil order.
