|
Chemical Weathering
|
The erosion or disintegration of rocks, etc., caused by chemical reactions.
|
|
|
Climate
|
The wether conditions in an area.

Groundwater
|
Water held underground in the soil or in pores and crevices in rock.
|
|
|
Humus

Karst Topography
|
A landscape that is characterized by numerous caves, sinkholes, fissures, and underground streams. Karst topography usually forms in regions of plentiful rainfall where bedrock consists of carbonate-rich rock, such as limestone, gypsum, or dolomite, that is easily dissolved. Surface streams are usually absent from karst topography.

The erosion or breakdown of rock into smaller fragments by natural physical agents with no chemicals involved; also called disintegration
|
|
|
Moraine
|
A ridge, mound, or irregular mass of unstratified glacial drift, chiefly boulders, gravel, sand, and clay.

|
Soil Profile
|
A vertical succession of horizons, commonly lettered A, B, C (beginning at the surface), that have been subjected to soil-forming processes, chiefly leaching and oxidation.
|
