AbstractRocks are divided into three main categories according to how they were formed: igneous, sedimentary or metamorphic processes. Rocks differ in their texture, mineral and chemical composition, and bedding characteristics depending on which of these three processes that formed them. Igneous rocks, which are also referred to as magmatic rocks, are formed from materials that come from the depths of the Earth. There are two categories of igneous rocks: intrusive (or plutonic) rocks and volcanic rocks. Sedimentary rocks are the product of the consolidation of loose sediment that has accumulated in beds. A metamorphic rock is derived from a pre-existing igneous or sedimentary rock that is transformed, to a greater or lesser degree, by the action of physical factors such as temperature and pressure, or chemical factors that include the addition of new minerals.
Summary(Plain Language Summary, not published)
The map was originally published online in the Atlas of Canada, 6th Edition as an interactive digital map derived from a shapefile and mapped online using MapServer, a platform for publishing spatial data to the web. In order to preserve the geographical content of this Edition during its publication from 1999 to 2009 all the maps have been converted from their online interactive form to a raster and made available in PDF and JPEG.
