Cool summer temperatures can actually produce higher photosynthetic efficiency in plants than can warmer conditions. It[clarification needed] was split[when?] [11][12] Erosion has exposed the roots of the mountains, which take the form of greenstone belts in which belts of volcanic rock that have been altered by metamorphism are surrounded by granitic rock. While gold mines still operate near Kirkland Lake and Timmins, there are no longer any active mines in Colbalt or Rouyn-Noranda a reality not uncommon for early mining towns. Spanning the width of North America, Canada is the worlds second largest country after Russia, and home to a diverse topography that ranges from deserts to tundra, plus coastlines that rim not only the Great Lakes but also three of the worlds five oceans.

If underground areas are included, the Canadian Shield covers even more area. Many mammals such as caribou, white-tailed deer, moose, wolves, wolverines, weasels, mink, otters, grizzly bear, polar bears and black bears are present. We want to hear from you. As the exposed part of the North American puzzle piece, the Canadian shield is made of hard rock, both igneous (formed by the rapid cooling of liquid rock) and metamorphic (rock that has been changed by enormous heat and pressure). Canadian weather is harsh and cold during the long winter months but is more varied during other seasons. This process is known as the winterization of summer. Most temperate forests dont get as much rainfall as tropical rainforests, but they do get enough rainabout 30 to 60 inches each yearto grow big trees. 3 What biome is South Florida?

Canada's topography is dominated by the Canadian Shield, an ice-scoured area of Precambrian rocks surrounding Hudson Bay and covering half the country. The Shield can be thought of as a jigsaw puzzle of different crustal blocks, sometimes known as provinces, welded together over time.
