Weathering
Action of the wind, waves, and water on a substance, such as rock, frost or even oil, that leads to disintegration or deterioration of the substance. Weathering is a natural process that impacts soil, rock formations and ice.
weathering
The physical and chemical disintegration alteration, and decomposition of rocks and minerals at or near the earth's surface by atmospheric agents.
wild flooding ...
Weathering is the chemical and mechanical breakdown of rocks due to atmospheric forces.
Wetlands are areas occasionally or always covered with shallow fresh or salt water.
weathering : The process during which a complex compound is reduced to its simpler component parts, transported via physical processes, or biodegraded over time.
ONION WEATHERING Onion weathering or exfoliation is a form of weathering where temperature differences between a rock and its outer layer are such that expansion and contraction cause the outer layer to peel away.
Physical weathering: Breaking down of parent rock into bits and pieces by exposure to temperature and changes and the physical action of moving ice and water, growing roots, and human activities such as farming and construction.
chemical weathering
attack and dissolving of parent rock by exposure to rainwater, surface water, oxygen, and other gases in the atmosphere, and compounds secreted by organisms. Contrast physical weathering.
chlorination ...
Chemical weathering
Dissolving of rock by exposure to rainwater, surface water, oxygen, and other gases in the atmosphere, and compounds secreted by organisms.

Ablation - The weathering of a glacier by surface melting, or rock weathering by hydraulic erosion. [Proceedings of the National Academy of Sciences of the United States of America ; v91; 365-369; 1994.
Serpentine soil Soil formed by the weathering of serpentine rock which contains high concentrations of various heavy metals.
Weathering, and the action of living organisms upon bedrock, form both stream substrates and terrestrial soils.
benthic referring to bottom zones or bottom-dwelling forms
benthos bottom-dwelling biota; the benthic community ...
Inceptisols are also considered to young soils of minimal weathering, but they are slightly more weathered than entisols.
Research by the Open University published in Geology (32: 157-160, 2004 [30]) indicates that this caused the rate of rock weathering to increase by 400%.
Acid rain also accelerates weathering in carbonate rocks and accelerates building weathering. It also contributes to acidic rivers, streams, and damage to trees at high elevation. Efforts to combat this phenomenon are ongoing.
Sources of lead resulting in concentrations in the air include industrial sources and crustal weathering of soils followed by fugitive dust emissions. Health effects from exposure to lead include brain and kidney damage and learning disabilities.
Saprolite: A soft, clay-rich, thoroughly decomposed rock formed in place by chemical weathering of igneous or metamorphic rock. Forms in humid, tropical, or subtropical climates.
Transpiration - the movement of water out of a plant through the pores in leaves or other plant parts.
Weathering - all physical and chemical changes produced in rocks or other deposits by atmospheric agents. These changes ...
