When the human transports and dumps a soil deposit is called as fill and this entire process is called as filling. When a transporting agent for a transported soil itself is a human then it is called as a fill. Bentonite :Д«entonite is nothing but the chemically adhered volcanic ash formed due to weathering. This soil consist mixture of inorganic soil, fine particles and decomposed black organic matters. It is mostly found in swamps and is mainly deposited due to flooding of river. These soil mainly originates due to imperfect drainage conditions. Moreover it dark colored clay which is more plastic. It generally consist of decomposed vegetative matter. Humus is dark drown organic type of soil. Transported soils and residual soils are formed by different agencies of nature. Sorting : Generally no sorting takes place.Д«esides these examples there are many more examples of soils which are formed by the different methods of transportation and deposition.Surface Texture :В Similar as of ice transported soil, it also generates striated surface texture.Shape : Non- spherical and angular particles are created.Sorting : In this case very less amount of sorting takes place.Д®ffects on Soil Transported due to Gravity :.Surface Texture : The sediments attain striated surface texture.Shape :В Angular particles are created due to this type of transportation.Size :В The sediments get considered grinding and this impact often changes its size.Sorting :В Progressive and more considerable sorting takes place.Surface Texture :В This impact creates frosted surfaces.Shape :В Sediments generally gain more degree of rounding than water transported sediments.Size :В Considerable reduction in the size of the sediments take place.Sorting : Considerable sorting takes place.Surface Texture : Generally the sand becomes smooth in nature and attains shiny and polished look.Shape : Sand and gravels tends to gain round surface.Size :В It is observed that the sediments transported through water tends to reduce their size and abrasion in suspended load is seen.Transportation Effects on Soil Sediments Effects on Water Transported Soil : This occurs mainly because of rainwash, continuous creep towards downside etc. These deposits are called as colluvial deposits The loose unconsolidated sediments gets deposited below or at the base of hill slope. Gravity plays important role in the transportation of these soil deposits. The soil deposits transported due to melting of ice are called as glacial deposits. Ice also plays important role in terms of moving soil soil particles from one place to other. The soil particles which travells due to blowing of wind from their originated place to other place is called as aeoline deposits. Many times the soil particles gets carried away due to heavy wind effect. Generally lake water is best example to find such deposits. The soil which is deposited because of the suspension in fresh still water is called as lacustrine deposits. The soil which is normally been deposited due to suspension in sea water are called as marine deposits. The natural soil which is generally been deposited due to suspension ( highly diffused mixing of water and soil) in running water are called as Alluvial Deposits. The transported soil is further classified based on their transportation and deposition method. The characteristics which might get effected due to method of transportation are : The soil can be transported due to wind, water, ice or any other atmospheric agent.Д«asically the transportation method decides the characteristics of transported soil. Here in case of transported soil the originated soil due to weathering of rocks moves or travells from its place of origin and gets redeposited at another place. Most of the time Igneous rocks such as basalt/ granite and Sedimentary rocks such as shale, sandstone/ limestone are prior materials or products of residual soils.Д«lack cotton soil and lateritic soils also falls into the example of residual soils.ДЄlso Read : Soil Stabilization Methods & NecessityДЄlso Read : Bearing Capacity of Soil and Its Importance Residual soil tends to lie over rock bed. What is Residual SoilДЄt the time of weathering of rocks ( breaking down of rocks due to weathering effects and atmosphere), if the product generated remains in the same position of their origination is called as residual soil. Basically on the formation of the soil, it can be grouped into 2 categories namely : Residual Soil and Transported Soil.

Generally when big rocks gets exposed to atmosphere, with time they get disintegrated and decomposes forming natural soil. The origin of the soil is nothing but the mechanical disintegration and chemical decomposition of rocks.
