which one of the following is not a factor of soil formation?
536512
Soil texture is not a factor which is responsible for the soil formation. Parent material (minerals and nutrients), Time, Climate, Relief and Organisms are the factors which are responsible for the soil formation.
1232975
Soil considered as an abiotic factor and a biotic factor. Because the soil is made out of dead organisms and dead twigs in also contains gravel and a biotic factor is features of the ecpsystem that are living or once were alive.

Technically, potting soil is nothing but dirt that no longer has the adequate elements necessary to support the growth of potted plants or indoor plants. Potting mix, however, doesn't have any soil but it is a blend of perlite, peat moss, vermiculite, fine barks, and more.

Topography. Topography has a significant impact on soil formation as it determines runoff of water, and its orientation affects microclimate which in turn affects vegetation. ... Water moving across the surface strips parent material away impeding soil development.

Humus, the organic material in soil, is composed of microorganisms (dead and alive) and decaying plants. The inorganic material of soil is composed of rock, which is broken down into small particles of sand (0.1 to 2 mm), silt (0.002 to 0.1 mm), and clay (less than 0.002 mm).

Climate is the typical pattern of the area over the long term, but weather is the actual daily condition. Of interest, climate is one of the five soil forming factors and has a significant influence on the properties of soil. Soils in warmer or wetter climates are more developed than soils in cooler or drier climates.

Soil has both biotic and abiotic factors in a savanna grassland. The abiotic factors of soil include minerals and texture of the soil that allow for the flow of water. The biotic factors include organic matter, water and air. Plants and trees grow in the soil, and it holds the moisture for them to absorb.

Soil is composed of small pieces of a variety of materials, so it is a heterogeneous mixture. Water is a substance; more specifically, because water is composed of hydrogen and oxygen, it is a compound.

Soil aggregates are formed through physical, chemical and biological activity below ground. They are even influenced by human factors, like tilling, walking on the surface, or even how you fertilize your garden. Formation of aggregates begins with finer soil primary particles binding together.

A soil's physical and chemical properties affect plant growth and soil management. Some important physical and chemical properties of soil are mineral content, texture, cation exchange capacity, bulk density, structure, porosity, organic matter content, carbon-to-ni- trogen ratio, color, depth, fertility, and pH.

Soil, Physical Characteristics of. Soil physical properties are those related to the size and arrangement of solid particles, and how the movement of liquids and gases through soils is affected by the particles. Soil mineral particles are derived from the weathering of rocks and minerals.
757047
Soil minerals form the basis of soil. They are produced from rocks (parent material) through the processes of weathering and natural erosion. Water, wind, temperature change, gravity, chemical interaction, living organisms and pressure differences all help break down parent material.
586409
There are three basic types of soil: sand, silt and clay. But, most soils are composed of a combination of the different types. ... While this is good for drainage, it is not good for growing plants because sandy soil will not hold water or nutrients. Silt is another type of soil.
423063
Soil properties. All soils contain mineral particles, organic matter, water and air. The combinations of these determine the soil's properties – its texture, structure, porosity, chemistry and colour.
792808
Topography has a significant impact on soil formation as it determines runoff of water, and its orientation affects microclimate which in turn affects vegetation. ... Water moving across the surface strips parent material away impeding soil development. Water erosion is more effective on steeper, unvegetated slopes.

The basic components of soil are minerals, organic matter, water and air. The typical soil consists of approximately 45% mineral, 5% organic matter, 20-30% water, and 20-30% air.

Soil is formed slowly as rock (the parent material) erodes into tiny pieces near the Earth's surface. Organic matter (fallen leaves, dead plants, and animals) decays and mixes with inorganic material (rock particles, minerals, and water) to form soil. Soil can be divided into many layers also called HORIZONS.
