Riding is a homonym of two distinct English words:
From the word ride:
From Old English *þriðing:
A riding is an administrative jurisdiction or electoral district, particularly in several current or former Commonwealth countries.
The word riding is descended from late Old English *þriðing or *þriding (recorded only in Latin contexts or forms, e.g., trehing, treding, trithing, with Latin initial t here representing the Old English letter thorn). It came into Old English as a loanword from Old Norse þriðjungr, meaning a third part (especially of a county), cf. farthing. The modern form riding was the result of initial th being absorbed in the final th or t of the words north, south, east and west, by which it was normally preceded.
A common misconception holds that the term arose from some association between the size of the district and the distance that can be covered or encircled on horseback in a certain amount of time (cf. the Walking Purchase).
Ridings are originally Scandinavian institutions.
In Iceland the third part of a thing which corresponded roughly to an English county was called þrithjungr. The island of Gotland and the Swedish province Närke were also divided into þrithjungar instead of hundreds.
An electoral district in Canada, also known as a "constituency" or a "riding", is a geographical constituency upon which Canada's representative democracy is based. It is officially known in Canadian French as a circonscription, but frequently called a comté (county).
Each federal electoral districts returns one Member of Parliament (MP) to the Canadian House of Commons; each provincial or territorial electoral district returns one representative — called, depending on the province or territory, Member of the Legislative Assembly (MLA), Member of the National Assembly (MNA), Member of Provincial Parliament (MPP) or Member of the House of Assembly (MHA) — to the provincial or territorial legislature.
While electoral districts in Canada are now exclusively single-member districts, multiple-member districts have been used at the federal and provincial levels. Alberta has had a few districts that returned from two to seven members: see Calgary, Edmonton and Medicine Hat. British Columbia had a mix of multiple-member districts in Vancouver and single-member districts elsewhere until the 1991 election, and Prince Edward Island had dual-member districts until the 1996 election.
In stratigraphy, bedrock is consolidated rock underlying the surface of a terrestrial planet, usually the Earth. Above the bedrock is usually an area of broken and weathered unconsolidated rock in the basal subsoil. The surface of the bedrock beneath soil cover is known as rockhead in engineering geology and identifying this, via excavations, drilling or geophysical methods, is an important task in most civil engineering projects. Superficial deposits (also known as drift) can be extremely thick, such that the bedrock lies hundreds of meters below the surface.
Bedrock may also experience subsurface weathering at its upper boundary, forming saprolite.
A solid geologic map of an area will usually show the distribution of differing bedrock types, i.e., rock that would be exposed at the surface if all soil or other superficial deposits were removed.
Soil scientists use the capital letters O, A, B, C, and E to identify the master soil horizons, and lowercase letters for distinctions of these horizons. Most soils have three major horizons—the surface horizon (A), the subsoil (B), and the substratum (C). Some soils have an organic horizon (O) on the surface, but such a horizon can also be buried. The master horizon, E, is used for subsurface horizons that have a significant loss of minerals (eluviation). Hard bedrock, which is not soil, uses the letter R.

After being leaked in September 2009 to Lil Wayne fan sites, "BedRock" was finally released on November 14, 2009. It was originally titled "Girl You Know" (the fan sites to which the single was leaked titled it "BedRock/Girl You Know") and the chorus was sung by Omarion and Lil Wayne's verse was different, but due to Omarion's departure from Young Money, he was replaced by Lloyd. The song was originally planned to be released as the 3rd official single of the album, however due to popular demand by fans it was released as the 2nd single.
