Shopping on line can be easy, simple and save you lots of money. It can also take a lot of your time, frustrate you, and result in unwanted purchases. Now the same can be said for regular high street shopping, but with the vast opportunity presented by the Internet it will pay you to spend a few minutes reading this and understanding how to better optimize your Silt shopping experience:
1. Compare - without doubt the biggest advantage that the Silt offers shoppers today is the ability to compare thousands of Silt at a time. This is a great thing, but not necessarily all the time! Too much can be daunting at times so take advantage of the great comparison sites and where possible let them do the hard work for you.
2. Research - if it has been said it will be on the internet. Ignorance is no longer a justifiable reason for buying the wrong thing. Take the time to research in detail everything that you could possible want to know about
3. Testimonials - don't know anybody that has bought a Silt? Wrong! If the Silt is good the internet will let you know. Use the Internet as a friend and get testimonials before you buy.
4. Questions - Got a question about Silt then search the Forums, FAQ's, Blogs etc. Don't be afraid to ask .....
5. Reputation - Never heard of the company selling Silt? Don't worry, no reason why you should know every company in the world, but you know someone that does! Use the internet to find out what people are saying about Silt and build up a picture of their reputation for sales, returns, customer service, delivery etc.
6. Returns - still worried that even after all of the above your Silt wont be what you want? Check out the returns policy. There is so much competition now that someone, somewhere is bound to offer the terms that you are comfortable with.
7. Feedback - happy with your Silt then let people know, after all you are depending on others people input in your buying decision, so why not give a little back.
8. Security - check for the yellow padlock on the Silt site before you buy, and the s after http:/ /i.e. https:// = a secure site
9. Contact - got a question about Silt, or want to leave a comment then check out the sites contact page. Reputable companies have them and respond.
10. Payment - ready to pay for your Silt, then use your credit card or PayPal! Be aware of companies that don't accept them, there may be genuine reasons but given the huge amount of choice you have when buying online there is no reason at all not to buy via credit card or PayPal.
Silt is
soil or
rock (geology) derived
granular material of a specific Particle size. Silt may occur as a soil or alternatively as suspended
sediment in a water column of any surface water body. It may also exist as deposition soil at the bottom of a water body.
Source
Silt is produced by the mechanical
weathering of rock, as opposed to the
chemical weathering that results in clays. This mechanical weathering can be due to grinding by glaciers,
eolian Abrasion (geology) (
sandblasting by the wind) as well as water erosion of rocks on the
stream beds of rivers and streams. Silt is sometimes known as 'rock flour' or 'stone dust', especially when produced by glacial action. Mineralogically, silt is composed mainly of
quartz and feldspar. Sedimentary rock composed mainly of silt is known as siltstone.
Silt, deposited by annual floods along the Nile River, created the rich and fertile soil that sustained the ancient Ancient Egypt civilization. This silt was depended on for this purpose. A decrease in silt deposited by the
Mississippi River throughout the
20th century has contributed to the disappearance of protective wetlands and barrier islands in the Mississippi River Delta region surrounding New Orleans.
Grain size criteria
In the Particle size (due to Krumbein), silt particles range between and mm (3.9 to 62.5 μm), larger than
clay but smaller than a
sand. In actuality, silt is chemically distinct from clay, and unlike clay, grains of silt are approximately the same size in all dimensions; furthermore, their size ranges overlap. According to the
United States Department of Agriculture Soil Texture Classification system, the sand-silt distinction is made at the 0.05 mm particle size. The USDA system has been adopted by the Food and Agriculture Organization (FAO). In the Unified Soil Classification System (USCS) and the AASHTO Soil Classification system, the sand-silt distinction is made at the 0.075 mm particle size (i.e. material passing the #200
sieve). Silts and clays are distinguished by their
plasticity (physics).

Environmental impacts
Silt can occur as a deposit or as material transported by a
stream or by a
current (water) in the
ocean. Silt is easily transported in water and is fine enough to be carried long distances by air as '
dust'. Thick deposits of silty material resulting from
aeolian deposition are often called
loess (a German term) or
limon (French). Silt and clay contribute to
turbidity in water.
One of the main causes of river siltation in the year 2006 is the result of slash and burn treatment of tropical forests. When the total ground surface is stripped of vegetation and then seared of all living organisms, the upper soils are vulnerable to both wind and water erosion. In a number of regions of the earth, entire sectors of a country have been rendered unproductive; for example, on the
Madagascar high central
plateau, comprising approximately ten percent of that country's land area, virtually the entire landscape is sterile of vegetation, with gully erosive furrows typically in excess of 50 meters deep and one kilometer wide.
Shifting cultivation is a farming system which sometimes incorporates the slash and burn method in some regions of the world. The resulting sediment load in rivers flowing to the west is ongoing, with most rivers a dark red brown colour. The resulting fish kills in most of these rivers have resulted in the process of extinction of a variety of
Madagascar's fish species.
