Lionâs Head, a wave-lashed arch of stone on the Lake Superior shores of Ontarioâs Sleeping Giant Provincial Park, exemplifies the Canadian Shieldâs rugged beauty. Viewed by satellite, the face of Canada reveals six clearly defined landform regions: Cordillera, Interior Plains, Canadian Shield, Great LakesâSt. Lawrence, Appalachian, and Arctic. All these regions occupy significant portions of Canadaâs vast expanse. Each possesses similar geologic structures, physical features, climatic conditions, soils, and vegetation. Considered as a whole, Canadaâs landforms encompass an unrivaled diversity of landscapes: spectacular mountain ranges, sweeping plains, rocky uplands, temperate lowlands, and frigid tundra. The forces of nature â our daily weather, for example â actively shape landforms. Some forces level landforms, others rebuild them.
