(1) slow chemical alteration by water seeping through the weathered rock material after rains and (2) mixing of the rock material with organic debris produced by the decay of plants. Smith and pun, chapter 14. Residue in a moderately humid climate (colman, 1982; • weathering, erosion, and soil are good examples of. Generally, high rainfall and temperature leads to deep weathering and soil leaching. The continuous interactions of the atmosphere, hydrosphere, and biosphere with earth materials. Hence the soil formation is a result of weathering of parent rock. Glassman, 1982), as most studies on andesite. The appalachians are smaller, rounded, gently sloping, and covered with plants. Mechanical weathering or physical disintegration of the parent rocks can occur due to the following processes: Soils may be formed in place from rock or formed in weathered rock and minerals that have been transported from where the original rock occurred.

(1) slow chemical alteration by water seeping through the weathered rock material after rains and (2) mixing of the rock material with organic debris produced by the decay of plants.
• weathering alteration of rock in its natural or original position:
Some soil organisms make humus, the material that makes soil fertile. Mechanical and chemical forces break down rocks. Soil is a mixture of four materials: This can come from weathered rock, volcanic chemical weathering happens much faster in warm places like northland than it does further south. 4.3 human activities affect soil.
