the irony should the metamorphic muscles that push mountains to the sky be driven by the pitter patter of tiny raindrops. " In the following chapters we look at this pitter patter, a synonym for exogenic processes that shape our landforms, starting with the most important process: weathering....
Co-located geophysical and geochemical datasets in the borehole show a remarkably consistent picture of linked chemical and physical weathering processes, acting over a 38-m-thick regolith divided into three layers: soil; porous, highly weathered saprolite; and weathered, fractured bedrock. The data...
(plants, animals, and humans at the end of the food chain). Chemical weathering controls the formation and evolution of soil, particularly (1) the concentration and distribution of chemical elements in the soil including the elements that controlsoil fertilityand (2) the physical properties of ...
Such microbial processes are involved either in the solubilization or the insolubilization of inorganic elements, in the weathering of minerals (silicates, phosphates, carbonates, sulfides, oxides) and in the formation of deposits (carbonates, oxides, sulfides, phosphates). They depend on the ...
The catena concept describes soil properties on hillslopes and implies a hydrological mass redistribution process that has been applied differently in different parts of the Earth. In tectonically active regions, it is mostly used to describe the redistribution of mass by overland flow leading to thic...
Physical erosion and chemical weathering rates beneath glaciers are expected to increase in a warming climate with enhanced melting but are poorly constrained. We present a global dataset of cations in meltwaters of 77 glaciers, including new data from 19 Asian glaciers. Our study shows that conte...

While color is the most obvious feature, many minerals display a wide variety of colors due to impurities or weathering. This makes color alone an unreliable identification tool in many cases. However, for some minerals, the color is diagnostic and consistent. ...
