Sand is a naturally occurring granular material composed of finely divided rock and mineral particles. It is defined by size, being finer than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e. a soil containing more than 85% sand-sized particles (by mass).
The composition of sand varies, depending on the local rock sources and conditions, but the most common constituent of sand in inland continental settings and non-tropical coastal settings is silica (silicon dioxide, or SiO2), usually in the form of quartz. The second most common type of sand is calcium carbonate, for example aragonite, which has mostly been created, over the past half billion years, by various forms of life, like coral and shellfish. It is, for example, the primary form of sand apparent in areas where reefs have dominated the ecosystem for millions of years like the Caribbean.
In terms of particle size as used by geologists, sand particles range in diameter from 0.0625 mm (or 1⁄16 mm) to 2 mm. An individual particle in this range size is termed a sand grain. Sand grains are between gravel (with particles ranging from 2 mm up to 64 mm) and silt (particles smaller than 0.0625 mm down to 0.004 mm). The size specification between sand and gravel has remained constant for more than a century, but particle diameters as small as 0.02 mm were considered sand under the Albert Atterberg standard in use during the early 20th century. A 1953 engineering standard published by the American Association of State Highway and Transportation Officials set the minimum sand size at 0.074 mm. A 1938 specification of the United States Department of Agriculture was 0.05 mm. Sand feels gritty when rubbed between the fingers (silt, by comparison, feels like flour).
Sand! is a 1920 American silent Western film directed by Lambert Hillyer and written by Lambert Hillyer based upon the Russell A. Boggs short story "Dan Kurrie’s Inning." The film stars William S. Hart, Mary Thurman, G. Raymond Nye, Patricia Palmer, Bill Patton, and S.J. Bingham. The film was released on June 20, 1920, by Paramount Pictures.
Copies of the film are in the Library of Congress and George Eastman House Motion Picture Collection.
A sandō (参道, visiting path) in Japanese architecture is the road approaching either a Shinto shrine or a Buddhist temple. Its point of origin is usually straddled in the first case by a Shinto torii, in the second by a Buddhist sanmon, gates which mark the beginning of the shrine's or temple territory. The word dō (道) can refer both to a path or road, and to the path of one's life's efforts. See, Karatedo. c.f. Taoism 道 There can also be stone lanterns and other decorations at any point along its course.
A sandō can be called a front sandō (表参道, omote-sandō), if it is the main entrance, or a rear sandō (裏参道, ura-sandō) if it is a secondary point of entrance, especially to the rear; side sandō (脇参道, waki-sandō) are also sometimes found. The famous Omotesandō district in Tokyo, for example, takes its name from the nearby main access path to Meiji Shrine where an ura-sandō also used to exist.

How do people in iraq dive -lol- it would really hurt, maybey brake about EVERY BONE IN YOUR BODY !
First 172 Foot World Record High Dive - Rick Winters
Occurred on June 2021 / Mandelieu, France This baby Sultan of the sand is leaving the sandy seafloor to dive in and out to escape a predator and goes back to hiding. I just put a camera close to him and to get him doing it in the shot. So funny! Contact licensing@viralhog.com to license this or any ViralHog video. Make money from your videos!

Sand diving at Horseneck.
Look at the amazing sand pool working it's magic safely stopping runaway trucks. Real name, arrestor bed - is a bed of loose material (such as gravel) designed to slow a vehicle that is out of control. They are mainly found on steep slopes where vehicles may likely lose control going downhill.

Parkour in abondoned sand quarry. Mad adventure, fun and an unforgettable experience. Clothes: https://leapparkour.cz/store/ Facebook: https://www.facebook.com/leapproducti... Instagram: https://www.instagram.com/leapparkour/ Edited by Daniel Pospíchal LeapParkour We are a parkour team founded in March 2015. We go in for various types of body movement. Above all it is parkour, freerunning. Our common goal is to show the ability of human body by videos and various performances. We perceive parkour as constantly self-improvement both physically and mentally in a natural environment. We would like to pass this idea on to help the others on their “way of the combat”.
