38
Q

A horizon

A

40
Q

B horizon

A

Primarily composed of mineral material w/ little organic matter

41
Q

C horizon

A

Very similar to parent material, least weathered horizon

42
Q

Cation exchange capacity (CEC)

A

The ability of a particular soil to absorb and release cations. Clay has a negative charge so can easily absorb cations for plants

43
Q

Base saturation

A

The proportion of soil bases to soil acids, expressed as a percentage

44
Q

Crust abundance

A

The average concentration of an element in Earth’s crust

45
Q

Ore

A

A concentrated accumulation of minerals from which economically valuable materials can be extracted

46
Q

Metal

A

An element with properties that allow it to conduct electricity and heat energy, and to perform other important functions

47
Q

Reserve

A

The known quantity of a resource that can be economically recovered

48
Q

Different types of surface mining

A

Strip mining, open-pit mining, mountaintop mining, placer mining

49
Q

Mine tailings

A

Unwanted waste material from mining

50
Q

Strip mining

A

Removal of “strips” of soil & rock to expose an underlying ore

51
Q

Open-pit mining

A

Large visible pit or hole is carved into ground

52
Q

Moutaintop mining

A

Miners remove entire top of mountain w/ explosives

53
Q

Placer mining

A

Looking for minerals, metals, & precious stones in river sediments

54
Q

Shifting agriculture

A

Unsustainable. Agricultural method in which land is cleared for a few years and soil is depleted of nutrients

55
Q

Soil compaction

A

Repeated trampling by humans, machinery, or animals causes a compaction of soil and reduction in pore space

56
Q

Desertification

A

Transformation of arable, productive land to desert or unproductive land (due to climate change or destructive land use)

57
Q

Nomadic grazing

A

Feeding of herds of animals by moving them to seasonally productive feeding grounds, often over long distances

58
Q

Sustainable agriculture

A

Enhances quality of soil, minimizes use of nonrenewable resources, economic viability for farmer, fulfills need for food & fiber

59
Q

A

Two or more crop species planted in the same field to promote a synergistic reaction

Q

Crop rotation

A

Crop species in a field are rotated from season to season

61
Q

Agroforestry

A

Trees & veggies are intercropped
