Document Summary
Bedrock geology surficial geology and ecozones of canada: area a variety of materials that underlay the continent from a variety of origins, frontenac axis tobermary to kingston, area above is igneous and area below is carbonate. Physiographic regions: defined by composite patterns of main elements of the landscape. Main elements: landforms, drainage features, soils, climate, vegetation, climate, land use: strongly influenced by processes that operate at earths surface (characterized by the flow of energy) Processes end up creating drainage systems, climate systems, ecosystems, geomorphic systems, tectonic systems: western cordillera. Predominantly an area influenced by mountains and predominant wind directions, create varying conditions because of the prevailing winds, affecting how much water flows where and vegetation type. Subduction, sea floor spreading, orogensis: interior plains. Rivers here behave very differently than those on the west coast due to erodability of the slopes and the soil conditions, flooding is rarer because it has been shaped by thousands of years: canadian shield.
