▼a Soil formation represents a suite of biogeochemical and physical processes that transform rock and sediment into a complex, organized system that sustains life. Soils are at the heart of the critical zone, the thin outermost veneer of the Earth' |

▼a I hypothesized that Quaternary climate change, driven by orbitally modulated insolation, is likely responsible for the observed patterns of soil evolution and preservation, and distributions of modern soil properties. Rapid climate change from g |

▼a Clays are the main soil formation product, and are a key variable for understanding the hydrology and biology of soils. Using the soil chronosequence database, a humped behavior in clay production was observed |

▼a Given the variability in past environmental conditions and uncertainty in the initial soil state, soil formation is highly variable. Using a probabilistic formulation of Jenny's soil state factor model, parameterized using a time-integrated meas |
