Temperature in Weathering,iations in weathering produced at different temperatures. Although there are differences caused by topography and other factors in any particular area (Fig. 4, Section 2-2), the following major facts cause the weathering in different zones: high average temperatures in moist regions increase vegetat

Trace Elements in Weathering,that are determined in the usual chemical analysis of a rock—there are minute quantities of other elements that are measured in parts per million (ppm) and known as trace or minor elements. These elements are interesting geochemically and are of considerable importance in plant and animal metabolism

Temperature in Weathering,ration, and chemical weathering is either nonexistent or very slight. As well as regional climatic differences there are regimes of soil climates which are in part described as microclimates. Each soil has a particular climate within which the soil flora and fauna live, and within which chemical cha
