Rock types of Canadas physiogaphic region?
Mау possibly уου tеll mе thе rock types (sedimentary,metamorphic,аnd/οr igneous) thаt аrе found іn Canada’s landform region. Eg Western Cordillera,Interior Plains,Canadian Sheild,Grt Lakes-St.Law Lowlands,Hudson Bay-Artic Lowland,Innutition Highlands, аnd Appalachian.
I am only going to answer one question. I reckon asking 9 different questions is pressing your luck.
In the Western Cordillera you will find t number of different types of rock. These would contain igneous rocks from which Canada mines iron and silver.
There are also metamorphic and sedimentary examples where potash, asbestos and mica can be found. But coal (a sedimentary rock) is probably the most abundant.

Rocks 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.
IN CANADA you will find metamorphic rock; sedimentary rock, and the igneous rock One of three major classes of rock produced by the cooling and solidifying of molten magma. All igneous rocks are crystalline and most resist erosion. Extrusive, or volcanic, igneous rocks, such as basalt, form by the rapid cooling of molten material at the surface. Intrusive, or hyperbyssal, rocks, such as dolerite, form in sills or dykes at intermediate depth. Plutonic rocks, such as granite, form in batholiths at greater depth. The major chemical constituent is silica. Acid rocks contain high amounts of quartz, feldspar or mica, and are light coloured. Basic rocks are darker and contain 45–55% silica, including minerals such as hornblende.
