interaction of rock with water and the atmosphere near Earth's surface causes weathering.
Fromation 1. The longer a soil has been forming, the thinner it becomes. 2. Microorganisms impede the formation of fertile soil. 3. Precipitation affects the rate at which nut…rients are removed from soil. i sorry i don't know which one it the best ..............:-(
No, soil formation doesn't affect the fertility of soil but soil looses its fertility by being exhausted.
Breaking down of rocks thousands of year ago is called formation of soil. This is called weathering rocks; they have a crack in them and when water gets into these cracks and …remains there , it may freeze in cold weather and form ice. Ice exerts pressure, thus breaking the rock over thousand of years, repeated weathering breaks rock into small grains of sand.
Soil is a complex material that evolves over time. An average soil is said to consist of 45% mineral matter, 25% water, 25% air, and 5% organic matter. The fo…rmation of soil starts with the parent material, the source of which could be from windblown or water transported sediments and organic matter. Over time, chemical and mechanical weathering processes break down this material into finer and finer particles. The rate of weathering is greatly affected by the climate. As plants and animals live and die, they add organic waste to the content of the parent material, and also aerate the material by digging and burrowing. Eventually a topsoil and subsoil will form from these processes, which can take hundred or thousands of years to produce even a meager thickness of productive soil.
soil characteristics develop as a result of their oriqin and development soils beqins as a particular rock material and develops slowly over many years, each soil is a pro…duct of a combination of: parent material, climate. livinq orqanisms, topoqraphy and time.
desert climates have fewer plants so less topsoil
Formation of soil takes a long process and takes more than one thousand years of continuous evolution. Rocks and minerals break into small particles due to weathering for a lo…ng time.These small particles when mixes with moss and organic matters a thin layer of soil forms. When plants grow on this thin layer of soil it attracts different types of animals including humane beings. Death of animals and humane beings and waste secreation of the animals form micro organism and bacteria on this thin layer of soil and soil become thick and rich.Thick and rich soil supports many plants and the process continue to the formation of soil further. Thus breaking of rocks due to weathering is the main cause of the formation of soil.Weathering is of two types- physical weathering and chemical weathering.Physical weathering like wind,water flow breaks the rock and chemical weathering changes it.In fact soil forms in four stages. stage I - breaking of the rocks into small particles, stage II- growing of plants over these small particles, Stage III- dead bodies of animals and waste secreation calls microorganism and bacteria, stage IV- soil become firm and rich to grow more plants and the process of soil formation continues. Thus,Soil forms out of different things in a gradual and continuous process like:rocks,minerals,and dead and decaying plants and animals. There are diffrent factors responsible for soil formation.Such as 1. topography, 2.climatic effect, 3.geological factors, 4. chronological factors, and 5.biological factors

Do you mean the importance of soil formation? This seems like a strange question. Can you rephrase it? When you realize that just about every bit of food you've ever eaten or… will ever eat originated in soil, you might consider soil formation important.
it is responsible because it helps the soil to get the amount of nutrients needed, so that if a plant is place there it can take some of the water from the soil in order to su…rvive.
Vegetation affects soil formation because vegetation influences the chemical and physical properties of the soil.
when rain water fall on the rock then it break the rock into smaller pieces.
