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
