The increased erosion (weathering) of plant cuticles by simulated "rain acidified with sulfuric acid may disrupt processes that occur at the leaf surface. The most important function of the cuticle is to reduce water (transpiration) loss. > Removal of leaf surface waxes has been reported to increase wettability of those surfaces.Leaves which had been wetted and dried are subsequently wetted more easily.The water repellency of a plant surface is important in preventing the establishment of infections from water-borne inocula.Dickinson proposed that the thigmotropic response of germ tubes of certain fungi is a function of the structure and thickness of the cuticle. Both of these features of cuticular waxes appear to be altered by simulated rain acidified with sulfuric acid. The apparent loss of surface... 

In spite of low copper contents, massive horizontal development renders porphyry deposits amenable to large-scale production methods. Porphyry deposits are associated with igneous activity and intmsion of molten rocks into cooler parts of the earth s cmst, often in connection with the formation of mountains. Erosion of mountainous areas exposes these deposits to weathering, and, under the right conditions, enables the formation of oxidized or secondary copper deposits. Copper mines in the United States are Usted in Table 2. 

Buildings, Monuments and Materials. Many materials used in man-made structures are subject to deterioration from normal weathering such as dissolution, mechanical fracture, erosion, and photochemical reactions. However, as shown by Amoroso and Fassina (43 the rates of deterioration have increased drastically since the advent of industrial pollution. Losses to Canadian heritage sites such as the federal parliament buildings has been significant and have been described by Weaver (44). 

In addition to runoff, rivers transport products of upland weathering to the oceans, forming a key link in the tectonic cycle of uplift and erosion. This interaction will be explored further in Section 6.6. 

Soil is a key component of the rock cycle because weathering and soil formation processes transform rock into more readily erodible material. Rates of soil formation may even limit the overall erosion rate of a landscape. Erosion processes are also a key linkage in the rock cycle...

The most stable minerals are often physically eroded before they have a chance to chemically decompose. Minerals that decompose contribute to the dissolved load in rivers, and their solid chemical-weathering products contribute to the secondary minerals in the solid load. The secondary minerals and the more stable primary minerals are the most important constituents of clastic sedimentary rocks. Consequently, the secondary minerals of one cycle of erosion are... 

The erosion process on slopes can be envisioned as a continuum between the weathering-limited and transport-limited extremes (Carson and Kirkby, 1972 Stallard, 1985,1995a). Erosion is classified as transport limited when the rate of supply of material by weathering exceeds the capacity of transport processes to remove the material. Erosion is weathering limited when the capacity of the transport process exceeds the rate at which material is generated by weath-...
