What major geographic feature is Canada known for?

Canada is renowned for its extensive coastlines, which are among the longest in the world. This vast network includes both the Atlantic and Pacific Oceans, as well as the Arctic Ocean to the north. The coastlines not only provide a rich variety of ecosystems but also contribute significantly to Canada's economy through fishing, tourism, and shipping routes. The geographic diversity created by these coastlines supports a wide range of wildlife and habitats, playing a crucial role in the country's identity and natural heritage.

In comparison, while Canada does contain mountainous areas, such as the Rockies, and has some prairie regions, it is the coastline that is particularly distinctive due to its length and the multitude of inlets and bays that make it unique. Dense jungles and desert plains are not characteristics found in Canada, as the country's climate and geography are defined by temperate and frigid zones, rather than tropical or arid environments.
