The ear canal functions as an entryway for sound waves, which get propelled toward the tympanic membrane, known as the eardrum. When sounds enter the middle ear, they are transmitted to tiny bones called the ossicles, which consist of the stapes, the incus, and the malleus. Sounds are later carried (in the form of waves) to the inner ear.

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.
