Natural causes? Erosion, from wind and water.

http://geography.about.com/od/physicalgeography/a/erosion.htm

I cannot seem to find any specific natural causes of sand deposition. I have read all of my chapters and google searched "sand deposition" and can't get anything useful. Please help.

Erosion from wind and water causes it to break down into minerals and popssibly decompose. I had the same question on a science test I got it right. but as for you it might not be.

Sand deposition occurs when sediments, including sand particles, are transported by natural forces such as wind and water and eventually settle or accumulate in a new location. It is a natural process that plays a significant role in shaping the Earth's surface.

While erosion from wind and water causes the breakdown and transportation of sediments, including sand, it is important to note that sand deposition is the result of specific conditions and dynamics within the environment. The deposition of sand can occur under various natural causes and processes, including:

1. Coastal processes: Sand deposition commonly occurs along coastal areas due to the interaction of waves, tides, and currents. The movement of water transports sand particles along the coast, and when these forces weaken or change direction, the sand is deposited, leading to the formation of beaches, sandbars, and barrier islands.

2. River and stream processes: Sand deposition can also occur in river and streambeds. When the velocity of water decreases, such as in areas of slack water or when a river enters a lake or ocean, the sand particles that were transported by the flowing water settle and accumulate on the riverbed or shoreline.

3. Aeolian processes: Wind can also play a role in sand deposition. In arid or coastal regions with strong wind currents, sand particles can be lifted into the air and transported over long distances. When the wind speed decreases or encounters an obstacle like vegetation or landforms, the sand particles settle and accumulate, forming sand dunes or sand sheets.

To find more specific information on sand deposition, it is helpful to search for keywords related to specific geographical regions or environments where this process is prominent. Also, consider using scientific databases or academic sources that specialize in geology, sedimentology, or earth sciences to find more detailed information on the topic.
