How are sediments transported and deposited in rivers?
sediments are transported by ocean rift, streams, river currents, wind (air). they are deposited according to size. The largest sediments are deposited first. The sediments settle into the sand and are carried by the stream. Near the mouth of the stream where the water moves slowly the small sediments settle out. The larger sediments get carried by the river into the sea then the samller sediments. The sea water dissolved minerals and soak the sediments and cement together. This eventually forms sediments. ...

Where does the dirt that covers or forms over the fossils in the strata of the earth come from?
The sediments are usually carried by water or are particles that settle out of water, but the sediments could be windblown. ...

How is suspended sediments removed from a completely mixed tank?
Assuming the liquid is water - add a flocculant (eg; Alum) and allow the sediment to settle. ...

What is meant by coagulation with reference to waste water treatment?
in waste water treatment some solid contaminants will settle out in settling basins or tanks leaving a pure water supernatant. If the particles are too small to settle either quickly or at all, chemicals (demulsifiers) are added to allow them to agglomerate (or coagulate) into large particles which will separate. ...
What is a storm water runoff treatment pond?
It is a pond that is designed, at a minimum, to retain and slow the flow of stormwater runoff so that solid pollutants, including sediments and trash, have an opportunity to settle out of the water column. Many are also designed such that the stormwater that is retained can infiltrate into the ground or pass through a wetland so chemical contaminants can be filtered out of the water, including metals, pesticides, and nutrients. ...

What are sediments and How are they involved in the formation of fossils?
Sediments are tiny pieces of earth that travel by being carried by either wind, water, or ice. they are involved with the process of fossils since it covers and buries an organism when it dies and eventually settle under great amounts of heat and pressure. ...
Asked in Geology
What is the movement of rock particles by wind water ice or gravity?
Erosion. Weathering is the physical and chemical breakdown of rock. Erosion is the removal of of weathered sediments. Transport is the movement of weathered sediments (say in suspension in river water) during the erosion process. Deposition is the laying down of the transported sediments in a new location. ...

How does chemical alum help the water treatment process?
it helps to coagulate dirty and makes them settle down at the bottom so the clean water can be filtered off ...
