This map shows the location of the Cordilleran physiographic region. The Cordilleran Region is divided into three large linear zones called the Eastern System, the Interior System and the Western System. Each system is further divided into areas and subdivided into mountains, ranges, plateaus,...

This map shows the location of the eastern physiographic regions which include the Appalachian Region and the St. Lawrence Lowlands.

This map shows the location of the Interior Plains physiographic region. The Interior Plains occupy the region between the Shield on the east and the mountains of the Cordilleran Region on the west. They join with the St. Lawrence Lowlands of eastern Canada through the United States and are...

Canada’s landscape is very diversified and comprises several distinctive areas, called physiographic regions, each of which has its own topography and geology. The physical geography of Canada comprises two great parts: the Shield and the Borderlands. The Shield consists of a core of old,...

This map shows the location of the Shield physiographic regions. The Shield is divided into five great regions: Kazan Region, Davis Region, Hudson Region, James Region and Laurentian Region. Each of these five regions is divided by subareas, and each of these subareas has its own geological...

Canada is a vast country comprised of a multitude of very different landscapes: Atlantic provinces, the Appalachians, St. Lawrence and Great Lakes lowlands, Canadian Shield, The Prairies, mountain ranges and high plateaus of the Canadian Cordillera, and northern Canada.

Most unconsolidated materials covering the Canadian landmass have glacial origins. Some sediments were entrained by glaciers and deposited at a distance without being sorted. Other sediments were picked up and reworked by glacial melt water, or transported and deposited by river or wind action....

An earthquake is the rapid shaking of the Earth’s surface that follows the sudden release of energy within the Earth. They are most commonly caused by movements along the edges of the plates that make up the Earth’s crust. Each year, more than 3500 mostly small earthquakes are recorded in or near...

Landslides are the downslope movements of sediment and rock. They can be found in any part of Canada, even in areas with very little relief. They happen in bedrock or in loose sediment, on land or under water. They can be large or small, rapid or slow, and generally occur without warning. This...

Avalanches are a mass movement of snow and ice down a hillside. They occur when unique circumstances of climate and topographic factors come together. This maps shows major avalanches beginning with the Rogers Pass avalanche in 1906 and extending to the 1999 avalanche in Kangiqsualujjuaq, Quebec.

Hail is precipitation consisting of ice pellets with a diameter of 5 millimetres or more. Hailstorms can occur anywhere in Canada. The most common period when hailstorms occur is from May to July, usually occurring with afternoon thunderstorms. Hailstorm with large hail pellets is spectacularly...

« Hurricane » is one of the names given to a tropical storm whose winds revolve around a center of low pressure called the eye, at a minimum speed of 120 kilometres per hour. At a center of hurricanes vortex - the eye - there is calm area of blue sky. Around this central column, there are very...

Tornadoes are columns of air that spin at a high rate of speed. They are small in scale but can be very violent. The area affected by a tornado's passage is between about 40 and 400 metres in width and between 1.7 and 36 kilometres in length. During a tornado the damage is due to wind as well as...

The magnetic field of the Earth is influenced by the electromagnetic environment of the solar system. The disturbed interplanetary environment changes the conditions of the natural electromagnetic environment of our planet and affects normal operation of space and ground technological...

Storm surges occur in coastal areas when strong onshore winds and low atmospheric pressure during passing storms raise water levels along the shore above predicted levels. Storm surges occur on all four Canadian coasts (Pacific, Arctic, Atlantic and Great Lakes). The most severe known surges in...

A tsunami is a sea wave or series of waves produced by large disturbances of the sea floor that are of relatively short duration. Such disturbances cause the water column to move vertically and the resulting wave energy to spread outwards across the ocean surface at high speed. Although tsunami...

There are many geologically active volcanoes along the Canadian Cordillera in British Columbia and the Yukon. Recurrent earthquakes below our feet and gigantic mountain ranges rising majestically upward remind us that this part of Canada is geologically active. The possibility of an eruption,...

Protected areas are composed of land, freshwater and marine areas set aside through legislation to protect representative examples of Canada’s ecosystems. They are created and managed by the federal, provincial and territorial governments. A small but increasing number is also administered by...

A protected area is a geographically defined area that is designated, regulated and managed to achieve specific conservation objectives. Canada has a long history of establishing protected areas. The first such area, Banff National Park, was created in 1885. Although there was a conscious effort...
