| A | B |
| Weathering | The physical breakdown and chemical alteration of rocks at or near Earth's surface |
| Mass Wasting | the transfer of rock and soil dowslope under the infunence of gravity |
| Erosion | the physical removal of material by mobile agents as water, wind, or ice |
| Mechanical Weathering | the physical forces that break rock into smaller and smaller pieces without changing the rock's mineral transformation |
| Chemical Weathering | the chemical transformation of rock into one or more new compounds |
| Frost Wedging | the process of many freeze-thaw cycles the rock is broken into pieces |
| Talus slopes | The sections of rock are wedged looses and may tumble into large piles |
| Sheeting | a process when large masses of igneous rock most granite, are exposed by erosion, slabs begin to break loose like the layers of an onion |
| Exfoliation domes | the outer layers expand more than the rock below and thus separate from the rock body and the continued weatherubg eventually causes the slabs to separate and spall off |
| Biological activity | the activites of organisms, including plants, burrowing animals, and humans. |
| Regolith | the layer of rock and mineral fragments produced by weathering |
| Soil | the combination of mineral and organic matter, water,and air |
| Soil Texture | proportions of different particle sizes which influences the soil's ablilty to retain and transit water, air |
| Horizons | soil into zones or layes |
| Eluviation | the washing out of the fine soil components |
| Leaching | the depletion of soluble materials from the upper soil |
| Laterite | soils in hot, wet tropical climates |
