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
