Soil is a complex material that evolves over time. An average soil is said to consist of 45% mineral matter, 25% water, 25% air, and 5% organic matter.
The formation of soil starts with the parent material, the source of which could be from windblown or water transported sediments and organic matter. Over time, chemical and mechanical weathering processes break down this material into finer and finer particles. The rate of weathering is greatly affected by the climate.
As plants and animals live and die, they add organic waste to the content of the parent material, and also aerate the material by digging and burrowing. Eventually a topsoil and subsoil will form from these processes, which can take hundred or thousands of years to produce even a meager thickness of productive soil.

What is the physical process responsible for soil creation?
Erosion
Does weathering go with metamorphic or igneas or sedimentary?
Weathering can happen to any rock. It is the first stage in the process that leads to the formation of sedimentary rock.

What is the state soil of Nebraska?

What are examples of soil properties?
1) soil texture 2) soil structure 3) soil compaction 4) soil organic matter 5) soil chemistry 6) soil fertility 7) soil horizons 8) soil temperature 9) soil moisture 10) soil pH 11) soil color Soils have always been classified in various ways by geographers and soil scientists. In 1974 the united nations introduce the "FAO World Soil Classification". In 1998 thisFAO system was replaced by the "World Reference Base for Soil Resources", which introduced new classifications (deleting old favourites like "podzols").

What is the process of soil formation called?
The process is known as Pedogenesis. Erosion and siltation are two of the mechanisms that contribute to pedogenesis.

Can rock turn into soil?
Yes, by series of processes that gradually breaks it down and disintegrates its parts into regoliths and soil. This process of soil formation is known as "Pedogenesis".
What role does physical weathering play in the formation process of sandstone?
question: What role does weathering play in the formation of soil? answer: soil forms as rock is broken down by weathering and mixes with other materials on the surface.
Does soil formation affect the fertility of soil?
No, soil formation doesn't affect the fertility of soil but soil looses its fertility by being exhausted.
