Factors affecting soil formation
Soils form from the interplay of five main factors namely Parent material, Time, Climate, Relief and Organisms.
1.factors of soil color:
This refers to the mineral material or organic material from which the soil is formed. Soils will carry the characteristics of its parent material such as color, texture, structure, mineral composition and so on. For example, if soils are formed from an area with large rocks (parent rocks) of red sandstone, the soils will also be red in color and have the same feel as its parent material.
2.factors of soil formationTime:
Soils can take many years to form. Younger soils have some characteristics from their parent material, but as they age, the addition of organic matter, exposure to moisture and other environmental factors may change its features. With time, they settle and are buried deeper below the surface, taking time to transform. Eventually, they may change from one soil type to another.
3.factors of soil formationClimate:
This is probably the most important factor that can shape the formation of soils. Two important climatic components, temperature and precipitation are key. They determine how quickly weathering will be, and what kind of organic materials may be available on and inside of the soils. Moisture determines the chemical and biological reactions that will occur as the soils are formed. A warmer climate with more rainfall means more vegetative cover and more animal action. It also means more runoff, more percolation and more water erosion. They all help to determine the kind of soils in an area.
4.factors of soil formationRelief:
releif and soils quality
This refers to the landscape position and the slopes it has. Steep, long slopes mean water will run down faster and potentially erode the surfaces of slopes. The effect will be poor soils on the slopes, and richer deposits at the foot of the slopes. Also, slopes may be exposed to more direct sunlight, which may dry out soil moisture and render it less fertile.
5.factors of soil formationOrganisms:
The source and richness of organic matter are down to the living things (plants and animals) that live on and in the soils. Plants, in particular, provide lots of vegetative residues that are added to soils. Their roots also hold the soils and protect them from wind and water erosion. They shelter the soils from the sun and other environmental conditions, helping the soils to retain the needed moisture for chemical and biological reactions. Fungi, bacteria, insects, earthworms, and burrowing animals help with soil aeration. Worms help break down organic matter and aid decomposition. Animal droppings, dead insects and animals result in additional decaying organic matter. Microorganisms also help with mineral and nutrient cycling and chemical reactions.
hey mate here is ur ans :-
_______________________________________
The factors responsible for the formation of soil :-
parent material: It is deposited by streams or derived from in-situ weathering.
climate - it is one of the imp factors because it affects the rate of weathering of parent material .
role of precipitation- Areas with little rainfall with high rate of evaporation led to the accumulation of salts in the soil.
Role of temperature: It is also play important role because fluctuations in temperature causes shrinking and swelling
biota - it improves the fertility of soil by fixing atmospheric nitrogen to ammonia
hopes it's helps uh ❗
