Cards in this set: Term Cronic Asid Definition the acid, H2CO3, formed when carbon dioxide dissolves in water, known in the form of its salts and esters, the carbonates. Term Chemical Weathering Definition is the process by which rocks are decomposed, dissolved or loosened by chemical processes to form residual materials. Term Creep Definition the tendency of a solid material to slowly move or deform permanently under the influence of stresses Term Erosion Definition is the carrying away or displacement of solids (sediment, soil, rock and other particles) usually by the agents of currents such as, wind, water, or ice by downward or down-slope movement in response to gravity or by living organisms Term Exfoliation Definition or sheet joints are surface-parallel fracture systems in rock often leading to erosion of concentric slabs. Term Hydrolysis   Definition is a chemical reaction during which one or more water molecules are split into hydrogen and hydroxide ions which may go on to participate in further reactions. Term Ice Wedging Definition When water infiltrates fractures in rock and freezes, the force of expansion is great enough to break. Term Landside Definition is a geological phenomenon which includes a wide range of ground movement, such as rock falls, deep failure of slopes and shallow debris flows, which can occur in offshore, coastal and onshore environments. Term Mass Movement Definition Mass movement is the down slope movement of earth materials under the influence of gravity. Term Mechanical Weathering Definition Takes place when rocks are broken down without any change in the chemical nature of the rocks. Term Mudflow Definition     Mudflows are rivers of rock, earth and other debris saturated with water. Term Definition Term Oxidation Definition The combination of a substance with oxygen. Term Parent Material Definition means the underlying geological material (generally bedrock or a superficial or drift deposit) in which soil horizons form. Term Definition Term Residual soil Definition the soil that is remaining after the soluble elements have been dissolved Term Soil Definition is the naturally occurring, unconsolidated or loose covering on the Earth's surface. Term Soil Erosion Definition The process by which soil is worn away. Wind, water, heat, cold and gravity or a mixture of all these things can cause erosion. The loss of plants often makes soil erosion worse as the roots of many plants resist wind and water. Term Soil Profile Definition A vertical strip of soil stretching from the surface down to the bedrock and including all of the successive soil horizons. Term Subsoil Definition is the layer of soil under the topsoil on the surface of the ground. Term Topsoil Definition is the upper, outermost layer of soil, usually the top 2 to 8 inches. Term Transported Soil Definition Soil not formed from the local rock but from parent material brought in from some other region and deposited, usually by running water, wind, or glacial ice. Term Weathering Definition The group of processes that change rock at or near Earth’s surface.
