This map shows the location of the Arctic physiographic regions which include the Innuitian Region, the Arctic Lowlands and the Arctic Coastal Plains.

Permafrost occurs when the ground remains at or below a temperature of 0oC for a minimum period of two years. Permafrost occurs not only at high latitudes but also at high...

This map shows the distribution of land cover types across Canada, based on satellite data obtained in 1995. The land cover map contains 31 classes: 12 forest; 3 shrubland; 7...

A watershed is an area that drains all precipitation received as a runoff or base flow (groundwater sources) into a particular river or set of rivers. The easiest way to...

The physical components of a watershed are rivers, lakes, ponds and reservoirs, groundwater aquifers, snowpacks, glaciers, ice fields, wetlands and precipitation. This map shows...

Apart from a source of drinking water, the water resources in watersheds supply water for irrigation and the production of hydroelectricity, and are a primary mode of...

A drainage basin is an area that drains all precipitation received as a runoff or base flow (groundwater sources) into a particular river or set of rivers. Canada’s major...

The map shows 3172 hydrometric stations, 1491 active and 1681 inactive, located on rivers and lakes across the country. All the stations on the map are situated in a drainage...

Hydrogeological regions are areas in which the properties of sub-surface water, or groundwater, are broadly similar in geology, climate and topography. Hydrogeology is the...

The percentage of subcompact cars in the total sales of light-duty vehicles with the model year 1990 is shown on this map for the populated areas. Light-duty vehicles include...

This map shows a simplified distribution of land cover types across Canada interpreted from satellite data obtained in 1995. Land cover has an important role in the water cycle...

Moisture regions illustrate moist (water surplus) and dry (water deficient) climate areas. The regions are a general guide to moisture surplus or deficit to be factored with...

Surficial hydrogeological materials show the distribution of sediment deposited in glacially influenced environments. Most drinkable groundwater resources in Canada occur in...

Rocks are divided into three main categories according to how they were formed: igneous, sedimentary or metamorphic processes. Rocks differ in their texture, mineral and...

The geologic time scale divides the 4.6 billion years of earths history into hierarchy of time periods. Every layer of rock corresponds to a specific time in the history of the...

The geologic time scale divides the 4.6 billion years of earths history into hierarchy of time periods. Every layer of rock corresponds to a specific time in the history of the...

Wetlands are areas characterized by relatively shallow water. These areas play an extremely important role in Canada's ecology. Canada has one of the largest areas in the world...

This map shows the number of tree species by ecoregion.There are about 180 species of trees in Canada. More tree species are found in Southern Ontario and along the St. Lawrence...

Ecozones are broad ecological zones on the earth's surface and cover a large range of ecosystems such as temperate forest, mountain ranges, grassland, taiga, arctic tundra,...

Nine zones indicate the areas where various trees, shrubs and flowers are most likely to survive. These zones are calculated based on average climatic conditions and altitude of...
