what is sedimentation?give four examples?



Sedimentation is the process of sellting down of dissoluble particles in a solvent as per it is kept undisturbed for some while.

e.g:-  1- settling down of stones in a bowl of water

2- mix mud with water & keep it 4 sometime; after, the mud will settle.

3- the settling of excess solutes in a solvent(in case the solution is saturated & the solute is solid)

4- well..........i told this much....... find one 4 yourselves..............go fast

Sedimentation simply means deposition of sediments in a low relief area (basin), by different medium (Air, water etc).
Example: The islands in the mouth (at The Bay of Bengal) of Ganges river, are formed by the deposition of sediments which were carried by Ganges herself.

Sedimentation means deposition of sediments in  the mouth of a river.
E.g. the sunderban deltas which are known as the world's largest deltas, are formed due to sedimentation.

The process of particles settling to the bottom of a body of water is called sedimentation. ... Layers of sediment in rocks from past sedimentation show the action of currents, reveal fossils, and give evidence of human activity. Sedimentation can be traced back to the Latin sedimentum, "a settling or a sinking down." For example, sand and silt can be carried in suspension in river water and on reaching the sea bed deposited by sedimentation. If buried, they may eventually become sandstone and siltstone (sedimentary rocks) through lithification. ... Desert sand dunes and loess are examples of aeolian transport and deposition.

On a daily basis we come across various incidents in which we have to separate one substance from the another to make it useful. Various methods are available by which we can separate substances which are mixed together. Sedimentation is one of the simplest separation methods. It is an essential concept that needs to be understood. Its importance is unquestioned and plays a crucial role with archaeology. It is a natural process and can be explained as the building up of layers of small particles like sand or mud. Weight and sedimentation is much related.


The process of sedimentation can be observed by a small experiment. Take a jar and fill it with garden variety mud, pour some water, shake well and keep it untouched for few minutes. In a while it can be noticed that the gravel and rocks have settled below, sand above and so on.  Basically the garden variety mud has formed layers of soil based on varied .


Similarly looking at a cliff, several layers in the surface of the cliff can be observed. These layers are caused by sedimentation. Over a long period of time, the grains of sand and mud build up, forming the layers. Fossils happen to be found in these layers. Logically, the quicker the bones are buried; the chances of survival are more as it is protected from scavenging animals and less damaged by weather. The sea, rivers and lakes are the best depositors of sand and mud. Dinosaur fossils were found to be nearer to the sea, lakes or rivers. A land-slide, where mud and rock fall down a mountain of a hill can also lead to a type of sedimentation.


Sedimentation can be used to separate particles based on their size by applying a centrifugal force to the required solution. In the process of Centrifugation, a centrifugal force is applied to a heterogeneous mixture which will separate  the mixture according to its density. The denser components shift away from the centrifugal axis whereas the less denser ones stay closer to the centrifugal axis. Thus separating the constituents of the mixture.

Sedimentation also helps to determine the medical conditions of a person. Sedimentation rate of RBC’s is an example. The sedimentation rate is performed by measuring how long it takes red blood cells (RBCs) to settle in a test tube. As time passes, RBC’s start to separate from the other plasma contents and they settle down at the bottom and serum will be formed above. The sedimentation rate or the ESR (erythrocyte sedimentation rate)is measured simply by recording how far the top of the Red Blood Cell layer has fallen (in millimeters) from the top of the serum layer in one hour.

Water treatment plants use the method of sedimentation to filter out unwanted particles from unclean water. Filtering through several layers of sand and soil, allowing certain sizes of particles to pass through.

Sedimentation in geology is the deposition of particles carried by Current or flow . The particles that carried by current or flow know as sediments .

The sediments is formed from weathering and erosion of mountains and the sediments is transporting by Current regime ( Gravity Force , waves , current ) , then it deposited in sedimentary basin and the sediment particles cemented to other and form sedimentary rock .

Sedimentary rock such as ( Conglomerate , Sandstones , Shales , Anhydraite , Salt , Limestone ,…. Etc ) .

Sedimentation . in this process the heavier insoluble impurities settles down.
Eg. 1. In the mixture of Sand and water. Sand settles down at the bottom
2.in the mixture of oil and water . water settles down and oil forms a layer.

Sedimentation- The process of settling down insoluble impurities at the bottom is called  Sedimentation.
For Ex- 1. Settling down sand in water
.2. Settling down mud in water.
