A variance has several meanings in business. In an accounting sense, a variance is the difference between an actual amount and a pre-determined standard amount or the amount budgeted. In a statistical sense, a variance is a measure of the amount of spread in a distribution.
CANADIAN GEOGRAPHY & CLIMATE. Canada is the second largest country on earth, covering an area of 10 million square kilometres (3.9 million square miles). Three oceans border Canada: the Pacific Ocean in the west, the Atlantic Ocean in the east, and the Arctic Ocean to the north.
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.
