Q

CONTROLS OF SOIL FORMATION:
The source of the weathered mineral matter from which soils develop

A

Parent material

20
Q

CONTROLS OF SOIL FORMATION :

Strongly influences weathering by the length of time that processes have been operating

21
Q

CONTROLS OF SOIL FORMATION:

Climatic elements, such as temperature and precipitation, that exert the strongest impact on soil formation

22
Q

CONTROLS OF SOIL FORMATION:

The types of abundance of organism present have a strong influence on the physical and chemical properties of soil.

23
Q

CONTROLS OF SOIL FORMATION:

Variations in topography can lead to the development of a variety of localized soil types
