By the end of the lesson, the pupils should have attained the following objectives (cognitive, affective and psychomotor)and be able to list agents of formation. PLAY. 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). All materials are subject to TERMLY review. The drifted material gets deposited miles away from the place of its formation. EkoExcel - 2020. Soil formation is the consequence of a combination of biological, physical, and chemical processes. ** QUALIFICATIONS 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). No, soil formation doesn't affect the fertility of soil but soil looses its fertility by being exhausted. Temperature is another climatic agent inf luencing the process of soil formation. What are the agents of soil erosion? Soil Conservation Practices: 1. It is formally on the url of clicksamplenote.com.ng now on classbasic.com. S= soil formation. 5. 4.

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 . Colloids are scarce and soil textural composition is dominated by coarse particles without aggregation capacity, the grain structure is particularly loose. He termed this soil formation ‘pedogenesis’. Demonstrates how man involved in breaking down of rock; Pupil’s Activities – List various activities of man that aids formation of rock. The following sections will be devoted to an analysis of terms and concepts such as soil, environment, soil-forming factors, etc. Plant roots also increase the amount of organic material in the soil and leave root channels behind. Sector - Lagos State Universal Basic Education Board (LSUBEB) Flashcards. Discuss the process of breaking down of rock. Animals eat plants and their wastes and eventually their bodies are added to the soil. Raindrops (especially in dry environments) create splash erosion that moves tiny particles of soil. High temperature hinders the process of leaching and causes an upward movement of solubl e salts. 3. What are the agent of soil formation 2 See answers Brainly User Brainly User Answer: Soils are formed through the interaction of five major factors: time, climate, parent material, topography and relief, and organisms. Toward the soil surface, these particles are incorporated into the allophanic groundmass resulting from actual soil formation.

Time is perhaps the most important factor when it comes to soil formation. Welcome! We believes teachers inspire our future. The different influences of these factors cause different soil horizons to form. 2. These are rain, temperature wind, man, animals and plants. Soils are formed by the interaction of five soil forming factors. The soil forming mixture is changed by the weather (climate), plants and animals, over a long period of time to form 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. When the weather is hot, the rocks are expanded and contracted … _________________ is the breaking down of rock by man, animals, plant’s roots and micro organisms. When these plants died, the leaves and roots inside the soil decay to form soil. The evolution of soils and their properties is called soil formation, and pedologists have identified five fundamental soil formation processes that influence soil properties. When the glaciers melt, huge mounds of soil are left behind, a part of which is carried by the stream. He left the ‘…’ in case there were other factors that he had not considered at the time.

When the soil dries out, the clay particles are forced closer to each other, creating and strengthening aggregates. The smallest particles travel the farthest. The process of soil formation is called weathering. These are also responsible for forming aggregates by cementing sand and silt particles. During the expansion and contraction, small particles of rock fall to form soil. As soil forms, plants begin to grow in it.
