Document Summary
To consider the relationship between canada"s physical and human geographies. To examine the nature of environmental issues in canada. Why is canada"s physical geography so essential to and understanding of its regional geography? (bone, 20122, 31) Physical landscapes differ in terms of: landforms, geology, climate, vegetation, solid, hydrology. Physiographic region: an area with distinct surface landform features (geomorphology) and underlying rock structure (geology) see figure 2. 1 p. 34. Geomorphology: the study of landforms and the process(es) of their genesis (from greek root words: geo-earth; and morpho- form) Three basic rock types: igneous- rocks formed when minerals crystalize during the cooling of molten liquids (ex. Granite (heat): sedimentary- rocks formed through the layering of mineral particles (ex. Limestone (deposition): metamorphic- existing rocks are altered through heat/pressure (ex. Erosional processes: the wearing away of something by a force: water, ice, wind. Challenges- imaging/understanding the ability of these processes to alter the physical landscape (force and time)
