Definition
| refers to the destructive processes on the surface of the earth that change the physical and chemical character of rocks. |
|
|
Term
|
Definition
| Physical disintegration of rocks by abrasion, impact, etc. |
|
|
Term
|
Definition
| Water seeps into fractures and expands wen it freezes. A type of Mechanical Weathering. |
|
|
Term
|
Definition
| Large temperature variations break rocks with repeated expansion and contraction. A type of Mechanical Weathering. |
|
|
Term
|
Definition
| Growing roots widen fractures in rock. |
|
|
Term
|
Definition
| Form in intrusive rocks (e.g. granites, diorites)with the remoal of overlying rock through erosion, the resulting decrease in pressure allows expansion of the underlying rocks and fractures. |
|
|
Term
|
Definition
| Decomposition of rock from exposure to atmospheric gases (oxygen, water vapor, and carbon dioxide) or liquid. |
|
|
Term
|
Definition
| Is the physical removal of rock particles and soils by moving water, wind, or glacial ice. |
|
|
Term
|
Definition
| Is the movement of eroded particles and soils by moving water, wind or glacial ice; Weathering processes continue during transportation. |
|
|
Term
|
Definition
| Is the transfer of rock soil down slope under the influence of gravity. |

Term
|
Definition
| Dissolution of limestone bedrock over time and related topographic and underground features. |
|
|
Term
|
Definition
| Cave formations. Formed by the slow deposition, drip by drip, of calcite from infiltrating groundwater. |
|
|
Term
|
Definition
| Dissolution of feldspar's to form clay's |
|
|
Term
| Caverns and caves are the result of.. |
|
Definition
| dissolution of limestone underground. |
|
|
Term
| Chemical weathering of feldspar's is the main source of... |
|
Definition
| clay minerals such as kaolinite, illmentite, bentonite and montmorillinite. It proceeds more slowly than the dissolution of calcite. |
|
|
Term
|
Definition
| of natural waters can have a strong effect on the chemical weathering of some earth materials. Is a measure of the activity of hydrogen ion in a solution. Hydrogen ion activity is dictated by the dissociation of water and interactions with other ions in solution. |

|
Definition
| Ranges from 0-14. 7 is neutral; 0-7 is an acid solution; 7-14 is a base solution. |
|
|
Term
|
Definition
| results as weathering is concentrated along joints and their intersections within the rock, and erosion of the less consolidated weathered "rind' leaves behind rounded pieces of unweathered bedrock. |
|
|
Term
|
Definition
| rocks weather at different rates and in different ways. Rocks may be more or less susceptible to weathering because of such things as composition or induration, the hardening of a rock through processes like increased temperature of formation, pressure of formation or cementation of particles by precipitated minerals. |
