The climate and ecology of different locations on the globe naturally separate into life zones, depending on elevation, latitude, and location. The generally strong dependency on elevation is known as altitudinal zonation: the average temperature of a location decreases as the elevation increases.
However, the False Creek Tunnel, part of the Canada Line rail-based transit system in Vancouver, at 29 m (95 ft) below sea level, is the lowest publicly accessible point in Canada. [16] Parts of Richmond, British Columbia are below sea-level, though behind dikes.
However, the human body has both short-term and long-term adaptations to altitude that allow it to partially compensate for the lack of oxygen. There is a limit to the level of adaptation; mountaineers refer to the altitudes above 8,000 metres (26,000 ft) as the death zone, where it is generally believed that no human body can acclimatize.
Canada has a vast geography that occupies much of the continent of North America, sharing a land border with the contiguous United States to the south and the U.S. state of Alaska to the northwest. Canada stretches from the Atlantic Ocean in the east to the Pacific Ocean in the west; to the north lies the Arctic Ocean. [1]
Not all National Topographic System maps strictly follow the National Tiling System's linear grid. Some maps also, as an "overedge", cover land in an area which would otherwise be covered by an adjacent map sheet, simply because the latter area does not contain enough land in Canada to warrant a separate printing.

Heating of solids, sunlight and shade in different altitudinal zones (Northern hemisphere) [5] A variety of environmental factors determines the boundaries of altitudinal zones found on mountains, ranging from direct effects of temperature and precipitation to indirect characteristics of the mountain itself, as well as biological interactions of the species.
