|---|---|
 Solution of minerals by acids occurring in soil and ground water | Acid action |
| Any stream-laid sediment deposit found in a stream channel and in low parts of a stream valley subject to flooding | Alluvium |
| Deposit of sediment originating at higher slope and accumulating at the base | Colluvium |
| Downhill surge of water-saturated soil, regolith, or weak shale | Earthflow |
| Removal of over-lying rock load from bedrock through denudation | Unloading |
| Water freezes, expands, rock breaks | Frost action |
| Mass wasting by humans (e.g. waste soil contamination, rock piles, undercutting slopes) | Induced mass wasting |
| Flow of water and mineral fragments, mass-wasting | Mudflow |
| Recesses formed in cliffs | Niches |
| Oxygen combines with metallic elements | Oxidation |
| MIneral particles layer over-lying bedrock | Regolith |
| Large quantities of rock falling from cliff | Rockfall |
| Rock is disintegrated by growing salt crystals during dry weather periods | Salt-crystal growth |
| Land disturbance to get minerals | Scarification |
| Degree of inclination from ground surface | Slope |
| Soil and regolith move down slow cuz they be getting wet or dry or stuff like frost action, and temperatures getting whack happen | Soil creep |
| Dudes looking for gems toss this stuff | Tailings |
| Slope formed by rapid accumulation of talus | Talus slope |
| Rocks get whipped chemically and physically through processes at Earth's surface | Weathering |
| Large mass of Earth and rocks down a hill | Landslide |
| Blocks of rock fall off slope | Topple |
| Sliding down curved surface | Slump |
| Regolith goes down a slope, smaller than flow | Fall |
| What is the main type of acid involved in acid action? | Carbonic acid |
| Forms when carbon dioxide dissolves in water | Carbonic acid |
| Carbonate sedimentary rocks are easy targets of what process? | Acid action |
| True or false: THe new minerals formed by oxidation and hydrolysis are stronger than the ones before | False |
| Salt-crystal growth causes zones of rock to break up and form these in cliffs | Niches |
| Loose rock fragment accumulation when rocks fall off a cliff | Talus |
