Soils at the bottom of a hill will get more water than soils on the slopes, and soils on the slopes that face the sun's path will be drier than soils on slopes that do not. [ 64 ] In swales and depressions where runoff water tends to concentrate, the regolith is usually more deeply weathered, and soil profile development is more advanced. [ 65 ]
Plants on calcareous grassland are typically short and hardy, and include grasses and herbs such as clover.Calcareous grassland is an important habitat for insects, particularly butterflies and ants, [2] and is kept at a plagioclimax by grazing animals, usually sheep and sometimes cattle.
The rock or sediment associated with a soil's development is referred to as its parent material, which is the starting point for the process of soil formation. During early formation, soils are not so different from their parent materials. With time however, soils will contain less features of their original parent material.
The Chalk Group is now divided into a White Chalk Subgroup and a Grey Chalk Subgroup, both of which are further subdivided into formations.These modern divisions replace numerous earlier divisions, references to which occur widely on geological maps and in other geological literature.
This is because soil formation, after which oxisols take more weathering to form than any other soil order, has been almost non-existent outside eras of extensive continental glaciation. This is not only because of the soils formed by glaciation itself, but also because mountain building, which is the other critical factor in producing new soil ...

Soil texture is the analysis and classification of the particle size distribution in soil. The relative amounts of sand, silt, and clay particles determine a soil's texture, which affects the appearance, feel and chemical properties of the soil. [12] Soil texture-by-feel method
It is a method in which a bud from the plant is joined onto the stem of another plant. [2] The plant in which the bud is implanted in eventually develops into a replica of the parent plant. The new plant can either divert its ways into forming an independent plant; however, in numerous cases it may remain attached and form various accumulations.
