Answer: types of animals
Soil formation or pedogenesis is the combined effect of physical chemical biological and anthropogenic processes working on soil parent material. Soil is said to be formed when organic matter has accumulated and colloids are washed downward leaving …

Hydraulic conductivity symbolically represented as is a property of vascular plants soils and rocks that describes the ease with which a fluid (usually water) can move through pore spaces or fractures.It depends on the intrinsic permeability of the material the degree of saturation and on the density and viscosity of the fluid. Saturated hydraulic conductivity K sat describes water …
Soil mechanics is a branch of soil physics and applied mechanics that describes the behavior of soils.It differs from fluid mechanics and solid mechanics in the sense that soils consist of a heterogeneous mixture of fluids (usually air and water) and particles (usually clay silt sand and gravel) but soil may also contain organic solids and other matter.
Soil particle density is typically 2.60 to 2.75 grams per cm 3 and is usually unchanging for a given soil . Soil particle density is lower for soils with high organic matter content and is higher for soils with high iron-oxides content. Soil bulk density is equal to the dry mass of the soil divided by the volume of the soil ; i.e. it includes air space and organic materials of the soil …
Frost heaving (or a frost heave) is an upwards swelling of soil during freezing conditions caused by an increasing presence of ice as it grows towards the surface upwards from the depth in the soil …
