Gravel

Gravel /ˈɡrævəl/ is composed of unconsolidated rock fragments that have a general particle size range and include size classes from granule- to boulder-sized fragments. Gravel is categorized by the Udden-Wentworth scale into granular gravel (2 to 4 mm or 0.079 to 0.157 in) and pebble gravel (4 to 64 mm or 0.2 to 2.5 in). One cubic yard of gravel typically weighs about 3000 pounds (or a cubic metre is about 1,800 kilograms).

Gravel is an important commercial product, with a number of applications. Many roadways are surfaced with gravel, especially in rural areas where there is little traffic. Globally, far more roads are surfaced with gravel than with concrete or tarmac; Russia alone has over 400,000 km (250,000 mi) of gravel roads. Both sand and small gravel are also important for the manufacture of concrete.

Geological formation

Large gravel deposits are a common geological feature, being formed as a result of the weathering and erosion of rocks. The action of rivers and waves tends to pile up gravel in large accumulations. This can sometimes result in gravel becoming compacted and concreted into the sedimentary rock called conglomerate. Where natural gravel deposits are insufficient for human purposes, gravel is often produced by quarrying and crushing hard-wearing rocks, such as sandstone, limestone, or basalt. Quarries where gravel is extracted are known as gravel pits. Southern England possesses particularly large concentrations of them due to the widespread deposition of gravel in the region during the Ice Ages.

Complete (The Smiths album)

Complete is a box set released by British band The Smiths on 26 September 2011. Standard versions contain their four studio albums (The Smiths, Meat Is Murder, The Queen Is Dead and Strangeways, Here We Come), a live album (Rank) and three compilations (Hatful of Hollow, The World Won't Listen and Louder Than Bombs) over 8 CDs or 8 LPs. A deluxe version contains the albums on both CD and LP formats as well as 25 7" vinyl singles and a DVD.

Despite its name it is not truly complete, as at least one song is missing on the standard versions: the B Side "The Draize Train" (studio version), though the live version of this instrumental is available on "Rank" and it's also available in the 7" of the deluxe edition. Other tracks missing from the Complete collection, "Jeane" and "Wonderful Woman" from the This Charming Man single are now available on the Deluxe 2CD version of the remastered 2008 compilation The Sound of The Smiths.

The package claims "Each album has been taken back to original tape sources and remastered by master-engineer Frank Arkwright, assisted by Johnny Marr at the Metropolis Studios in London". The CD version is presented "in VINYL REPLICA sleeves", actually the usual miniature-LP packaging.
