Organisms (living things including man, plants and animals) All living organisms play an active role in the soil formation processes. Soil formation takes place during a process called weathering .There are three forms of weathering: Physical weathering, Biological weathering, Chemical weathering ; Physical weathering This involves the disintegration of rocks into smaller fragments by physical weathering agents . Soil formation begins with the physical and chemical breakdown of the earth's rocks, caused by atmospheric agents. Soils are formed by the interaction of five soil forming factors. Weathering – Soil formation factors and processes – Components of soils Weathering A process of disintegration and decomposition of rocks and minerals which are brought about by physical agents and chemical processes, leading to the formation of Regolith (unconsolidated residues of the weathering rock on the earth’s surface or above the solid rocks). They are parent material, climate, biota (organisms), topography, and time. This disturbs the soil and makes it susceptible to erosion. The period taken by a given soil from the stage of weathered rock (i.e. _________________ is the breaking down of rock by water, wind, etc. Weathering is the breaking down of rocks into smaller (tiny) particles to form soil. 2. As a result, soil in these areas have a rich content of humus. 5. Sector - Lagos State Universal Basic Education Board (LSUBEB) … Other materials like dead plants and animals and other materials carried by stream or water mix with broken rock materials to form soil forming mixture or materials.

When the glaciers melt, huge mounds of soil are left behind, a part of which is carried by the stream. Soil Formation. Soil Formation and Properties. When these plants died, the leaves and roots inside the soil decay to form soil. Gravity: an agent of physical weathering and causes abrasion. 1. The relative influence of each factor varies from place to place, but the combination of all five factors normally determines the kind of soil developing in any given place. Animals eat plants and their wastes and eventually their bodies are added to the soil. Soil formation is the consequence of a combination of biological, physical, and chemical processes. Strengthening Mathematics and Science Education Project (SMASE), Cycle 1 Training - 2018 What are the agents of soil erosion? The evolution of soils and their properties is called soil formation, and pedologists have identified five fundamental soil formation processes that influence soil properties. Soil formation is fastest in hot, moist climates and slowest in cold, dry climates. 3. To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson.

When rainfall, the materials decay to form soil. High temperature hinders the process of leaching and causes an upward movement of solubl e salts. The drifted material gets deposited miles away from the place of its formation. Learn. Soil should ideally contain 50 percent solid material and 50 percent pore space. Soil is the most important renewable natural resource. o = organisms. Toward the soil surface, these particles are incorporated into the allophanic groundmass resulting from actual soil formation. Biological Weathering is a natural phenomenon that occurs on rocks due to living organisms. Also, rainfall on dried plants and dead animals helps to decay to form soil. The process of soil formation is called weathering. Rainfall helps to wash down different particle from the rocks. Soil structure can be classified according to the presence of colloidal soil particles and their interaction with coarser particles. Do you know that soil is formed from rocks?

We believes teachers inspire our future. When soil is formed, plants grow and their roots are deepen inside the soil. Soil is said to be formed when organic matter has accumulated and colloids are washed downward, leaving deposits of clay, humus, iron oxide, carbonate, and gypsum, producing a distinct layer called the B horizon. 4. Overgrazing, and deforestation are the major biotic agents, cause soil erosion. _________________ is the breaking down of rocks into smaller particles. Soil with 2:1 type of phyllosilicate clay minerals (e.g., montmoriollinite) typically have high cation exchange capacity (CEC), which allows them to bind with polyvalently charged organic matter complexes to form microaggregates (Amézketa, 1999). Soil clay particles have varying effects on aggregate formation, depending on its type. **** About CRN r = relief (or topography) p = parent material. The plants mature, die and new ones take their place. These processes, known as weathering, chip away rock fragments and thus modify its inherent physical and chemical characteristics. 2.
