Reconstruction of depositional environment: environment conditions reconstructed by: Colluvial effects suggest: changes in depositional env: Define meromictic lake and why its important: Soils are: 2 types of modification: Top to bottom or vice versa: diagenesis: R (reefer): 5 things that influence pedogenesis: climate, topography, biota, parent material, time. Temp and moisture influence soil: desert (few plants and animals, temperate env (many plants and animals, northern climate (conifers) Gives context for sites on: microscale by: Features formed by geosphere (relief 5 things): Dunes: hydrosphere, define barchans and erg: Channels (2 orders): influenced by (3 things), define sinuous channel, define braided channel: Erosional: shoreline cliffs (4 stage process): Depositional: beach ridges, spits, bars, cryosphere.
