acid mine drainage
Acid mine drainage, acid and metalliferous drainage , or acid rock drainage refers to the outflow of acidic water from metal mines or coal mines
longwall mining
Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice
Surface mining
Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit are removed
facets
Facets are flat faces on geometric shapes
gypsum
Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4·2H2O
rock cycle
The rock cycle is a basic concept in geology that describes the time-consuming transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous
Detrital
Detritus is particles of rock derived from pre-existing rock through processes of weathering and erosion
secondary rocks
Sedimentary rocks are types of rock that are formed by the deposition and subsequent cementation of that material at the Earth's surface and within bodies of water
physical characteristics
Human physical appearance is the outward phenotype or look of human beings
ore
An ore is a type of rock that contains sufficient minerals with important elements including metals that can be economically extracted from the rock
metamorphic
Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form"
erosion
In earth science, erosion is the action of surface processes that remove soil, rock, or dissolved material from one location on the Earth's crust, then transport it away to another location
