Q: Information:  - The Montreal Alouettes are a Canadian football team based in Montreal, Quebec. Founded in 1946, the team has folded and been revived twice. The Alouettes compete in the East Division of the Canadian Football League (CFL) and last won the Grey Cup championship in 2010. Their home field is Percival Molson Memorial Stadium for the regular season and as of 2014 also home of their playoff games.  - Montreal Olympique were a professional soccer team based in Montreal that played in the NASL . They played three seasons from 1971 to 1973 , but saw little success . Notably , Graeme Souness appeared for the club in 1972 . The Olympique 's home ground was the Autostade . The NASL would return to Montreal in 1981 in the form of the Montreal Manic .  - The Autostade (the English name Automotive Stadium was rarely used) was a Canadian football stadium in the Victoriatown neighbourhood of Montreal, Quebec that stood at the north-west corner of the Cité du Havre sector of the Expo 67 site. It was the home of the Montreal Alouettes from 19681976, except for a brief period in 1972 when the team returned to its previous home, Molson Stadium.  - Montreal Manic were a professional soccer team based in Montreal that played in the North American Soccer League.

Q: Information:  - Soil is a mixture of minerals, organic matter, gases, liquids, and countless organisms that together support life on Earth. Soil is a natural body called the pedosphere which has four important functions: it is a medium for plant growth; it is a means of water storage, supply and purification; it is a modifier of Earth's atmosphere; it is a habitat for organisms; all of which, in turn, modify the soil.  - Arenite (Latin "Arena", sand) is a sedimentary clastic rock with sand grain size between 0.0625 mm (0.00246 in) and 2 mm (0.08 in) and contain less than 15% matrix. The related adjective is "arenaceous". The equivalent Greek-derived term is psammite, though this is more commonly used for metamorphosed sediments.  - A mineral is a naturally occurring chemical compound, usually of crystalline form and abiogenic in origin. A mineral has one specific chemical composition, whereas a rock can be an aggregate of different minerals or mineraloids. The study of minerals is called mineralogy.  - Sandstone ( sometimes known as arenite ) is a clastic sedimentary rock composed mainly of sand - sized minerals or rock grains . Most sandstone is composed of quartz and / or feldspar because these are the most common minerals in the Earth 's crust . Like sand , sandstone may be any color , but the most common colors are : tan , brown , yellow , red , grey , pink , white , and black . Since sandstone beds often form highly visible cliffs and other topographic features , certain colors of sandstone have been strongly identified with certain regions . Rock formations that are primarily composed of sandstone usually allow percolation of water and other fluids and are porous enough to store large quantities , making them valuable aquifers and petroleum reservoirs . Fine - grained aquifers , such as sandstones , are better able to filter out pollutants from the surface than are rocks with cracks and crevices , such as limestone or other rocks fractured by seismic activity . Quartz - bearing sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts .  - Psammite (Greek "psammos", sand) is a general term for sandstone. It is equivalent to the Latin-derived term arenite. Also, it is commonly used in various publications to describe a metamorphosed sedimentary rock with a dominantly sandstone protolith. In Europe, this term was formerly used for a fine-grained, fissile, clayey sandstone. Pettijohn gives the following descriptive terms based on grain size, avoiding the use of terms such as "clay" or "argillaceous", which carry an implication of chemical composition:  - Silt is granular material of a size between sand and clay, whose mineral origin is quartz and feldspar. Silt may occur as a soil (often mixed with sand or clay) or as sediment mixed in suspension with water (also known as a suspended load) in a body of water such as a river. It may also exist as soil deposited at the bottom of a water body. Silt has a moderate specific area with a typically non-sticky, plastic feel. Silt usually has a floury feel when dry, and a slippery feel when wet. Silt can be visually observed with a hand lens.  - Gravel 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 and pebble gravel. One cubic metre of gravel typically weighs about 1,800 kg (or a cubic yard weighs about 3,000 pounds).  - 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.  - Latin (Latin: ) is a classical language belonging to the Italic branch of the Indo-European languages. The Latin alphabet is derived from the Etruscan and Greek alphabets.
