1 Monument Valley, Utah. What weathering processes contributed to the development of these remarkable rock formations? Weathering Includes Physical, Chemical, Biological processes WEATHERING CHAPTER 7 Weathering is a Series of Physical, Biological, and Chemical processes. Modifies rocks, minerals, and sediments. Produces sediment transported by Erosion. Enables growth of new minerals (called sedimentary minerals) through crystallization. Produces Soil. Weathering Mechanisms Physical and biological weathering causes rock to fracture and fragment Chemical weathering attacks exposed surfaces Physical Weathering causes Fragmentation of Rock. Pressure Release, Abrasion, Freeze Thaw, Hydraulic Action, Growth of Salt Crystals, other Physical Means Physical weathering is aided by rock joints and other types of fractures Pressure release jointing Exfoliation Wind abrasion forming Ventifacts FREEZE THAW Talus slope created by Ice Wedging Desert pavement 1
2 Soil, Spheroidal Weathering Hydrolysis, Oxidation, and Dissolution Are Chemical Weathering Processes. Water molecule is polarized. Attracts cations. Universal Solvent Hydrogen bond polar FREEZE THAW Talus slope created by Ice Wedging and Natural Bridges are products of weathering Hydrolysis is the chemical reaction (cation exchange) of a compound with acidic water. Oxidation = O bonds with cation (K, Ca, Fe, Mg) by electron sharing (covalent) Dissolution occurs when carbonic acid dissolves the mineral calcite (found in limestone). Orthoclase feldspar becomes Kaolinite (a) CO 2 + H 2O H 2CO 3 carbon dioxide gas + water carbonic acid (b) CaCO 3 +H 2CO 3 Ca HCO3 calcite + carbonic acid dissolved calcium + dissolved bicarbonate 2KAlSi3O8+2H+H 2CO3+H2O Al2Si2O5(OH)4+2K+2HCO3+4SiO2 feldspar + rainwater react to form clay + dissolved salts + silicic acid Fe2O3 Hematite Widespread dissolution causes: Karst Topography Forms of Limestone CaCO 3 Biological Weathering Involves Both Chemical and Physical Processes Coquina Micrite Chalk Travertine or Flowstone Skeletal Limestone 1. Simple breaking 2. Movement and mixing 3. Carbon dioxide produced d by respiration forms carbonic acid 4. Organisms influence moisture in soil 2
3 Sedimentary Products Result from All Three Types of Weathering Rocks and Minerals Can Be Ranked by Their Vulnerability to Weathering weathered granite outcrop Clays are phyllosilicates sheet structures composed of silica tetrahedra. The Effects of Weathering Can Produce Climate Change. Volcanic outgassing of Greenhouse Gas part of Carbon Cycle The Uplift Weathering Hypothesis: Global rate of chemical weathering dependent on availability of fresh rock. Atmospheric carbon dioxide decreases as new silicate rich crust is exposed to hydrolysis during orogenesis (i.e., raising the Himalayas) Global Cooling or Global Warming? BOTH it depends on the time span under consideration. Weathering Produces Soil SOIL FORMATION influenced by: biological processes, nature of parent rock, climate, topography, and time. 3
4 HOT, ARID ENVIRONMENTS Salts accumulate at the surface due to evaporation. Frost, abrasion, and slaking break the rocky surface into sand or gravel. Wind blows larger particles away creating desert pavement. CLIMATE CRITICAL in SOIL FORMATION Physical Weathering dominates in regions of low temperature and low rainfall. HOT, HUMID ENVIRONMENTS INSOLUBLE RESIDUES with crusts of iron oxides (LATERITE) and aluminum oxides (BAUXITE) COLD ENVIRONMENTS Mechanical breakdown (by ice wedging) is the major weathering process. Chemical Weathering dominates in regions of high temperature and high rainfall. Soil Horizons Animation Seasonal freezing allows vegetation debris to accumulate in the soil. Soil surface becomes extremely rich in organic plant debris, known as the HUMUS LAYER Soil Erosion Is a Significant Problem. Fluvial Erosion particles of sediment removed by flowing water in a channel: Suspension Bed Load Saltation Mass Wasting sediment moved by gravity: Landslides Mudflows Eolian Erosion sediment moved by wind. Raindrops to Sheets to Rills to Gullies! HUMID, MIDLATITUDE ENVIRONMENTS There Are 12 Orders in the Soil Classification System. Mollisols Alfisols Entisols The Power of Wind Eolian Erosion! Inceptisols Ultisols Gelisols U.S. SOIL MAP 4
5 Residual soils contain accumulations of stable elements and compounds Al, Fe bauxite, gibbsite Oxisols Sedimentary Minerals Microcrystalline quartz (chert, agate, quartz) SiO2 Clay kaolinite Calcite CaCO3 Hematite/limonite Fe2O3 Granite quartz, feldspar, biotite, amphibole Which climate, weathering processes and soil profiles are likely in each of these five settings?
