One descriptor would be 'an aeolian deposit. Which means a deposit caused by wind.
An alternative would be the name Loess, which means the same thing. Downwind of a desert region, Loess deposits may be many tens of metres in thickness.

Where would you expect to find sand deposits on the curve in a river?
A sand deposit will usually occur on the curve of a river. It will show when the river is low, and all of the water will usually flow to the middle or the inside of the curve.Ê
Need to know type of sand?
There are a lot more types than you'd think! The white sand of tropical and subtropical settings are comprised of limestone and may have coral and shell fragments. The gypsum sand dunes of the White Sands National Monument are famous for their bright white colour.Arkose is a sandstone with lots of feldspar in it and granite rock outcrop.Some sands have chlorite, glauconite, gypsum or magnetite.Some sands come from volcanic basalts and obsidian.Many sands have iron impurities within the quartz crystals of the sand, making them appear a deep yellow colour.Some sand deposits have garnet (a type of gem) including other small gemstones.Bet you didn't know sand was so glamorous!
What is the difference between dunes and loess?
Sand dunes are made from mainly one mineral - sand or quartz grains and they form and move to develop a typical cross bedding structure. Loess however is wind blown silt (a mixture of sand and clay) with a fine grain size typically in the 20-50 micrometer range. The deposits are typically non stratified and cover a wide area. They also quickly become loosely cemented after deposition and are not reworked as are sand dunes. The source material for loess deposits is the rock flour left by retreating Ice sheets and the deposits therfore form in temperate regions while Sand Dunes are an indication of arid desert (tropical) conditions.
Deposits of sediment that run along the shore?
often salt or potassium in other cases
What is finely ground silica?
Silica mining and manufacturing companies grind the mined ore down to an average particle size ranging from 15 to 3 microns. All of the raw ore is naturally occurring silica that is typically surface mined. The finished product is much finer than industrial sand (e.g., playground sand, golf sand, filtration sand, etc.). The overall particle size distribution typically falls below a 200 mesh screen or 74 microns. The particle size distribution range is typically between 74 microns down to 5 microns. The finished material is fine in particle size similar to baking flour.Quartz is the most common silica crystal and the second most common mineral on the earth's surface. It is found in almost every type of rock; igneous, metamorphic and sedimentary. While quartz deposits are abundant, and quartz is present in some form in nearly all mining operations, high purity and commercially viable deposits occur less frequently. Silica sand deposits are most commonly surface-mined in open pit operations, but dredging and underground mining are also employed. Extracted ore undergoes considerable processing to increase the silica content by reducing impurities. It is then dried and sized to produce the optimum particle size distribution for the intended application. {sourcehttp://www.ima-na.org/industrial-sand}
Wind carrying sand grains deposits the sand when the wind?
Wind carrying sand grains deposits the sand when the wind slows down or hits an obstacle.
What deposits sand on beaches?
water
A sedimentary rock formed from sand deposits is called?
A sedimentary rock formed from sand deposits is called a 'Sandstone' or generically a 'Psammite'.
What is a sedementary rock formed from sand deposits?
Sandstone is formed from deposits of sand.
How do sand dunes and loess deposits form?
Wind erosion and deposition may form sand dunes and loess deposits. When the wind strikes an obstacle, the result is usually a sand dune!
What are the characteristics of aeolian deposits?
Aeolian deposits can be smooth sand sheets that can resemble a desert floor. They can be mobile sands that form active sand sheets or rugged vegetated sand sheets
