|
Definition
| Weathering, Mass Movements, Erosion, Transportation of materials, and Deposition |
|
|
Term
|
Definition
| Process by which rocks disintegrate or dissolve in place |

Term
| What are the three types of weathering? |
|
Definition
| Physical (mechanically breaking down rocks), Chemical (decomposing rocks in water via chemicals reactions), and Biological |
|
|
Term
| What are 4 examples of physical weathering? |
|
Definition
| Dilation (pressure release, fractures), Thermoclasty (thermal shock and fatigue failures as a result of rock crystals expanding and contracting with temp), Freeze Thaw (water in joints freezes and expands), and Salt Weathering (Expansion of salt crystals in rocks) |
|
|
Term
| What are 3 examples of chemical weathering? |
|
Definition
| Hydrolysis (rxn between water and a mineral/alkali metal producing clay mineral), Carbonation (carbonic acid in rain reacts with Ca, Mg, K, and Na), and Oxidation and Reduction (Fe combines with oxygen) |
|
|
Term
| Describe differential weathering. |
|
Definition
| Different rock masses or different sections of the same rock weather at different rates |
|
|
Term
| What are the 3 products of weathering? |
|
Definition
| Soil, regolith, and sediment |
|
|
Term
|
Definition
| Process by which sediments are deposited, leading to its accumulation |
|
|
Term
| What are the 4 classes of Mass Movements? |
|
Definition
| Falls and Avalanches (little water, very fast), Slides (After lots of precip, slower than F&A), Flows (Lots of water, very fast), and Creep |
|
|
Term
| What are 5 triggers of mass movements? |
|
Definition
| Heavy rain, earthquakes, thawing of frozen ground, loss of vegetation, and construction |
