Which provinces are included in the interior plains of Canada?

The interior plains of Canada are characterized by vast, flat areas primarily composed of sedimentary rock and rich agricultural land. The provinces and territories included in this region are known for their extensive prairies and are significant for farming and ranching.

The correct choice identifies the Northwest Territories, Alberta, Saskatchewan, Manitoba, and a small part of British Columbia as part of the interior plains. These areas share similar geological features and climate conditions conducive to agriculture and grazing. The presence of fertile soil in these plains has made them a crucial region for both crop production and livestock farming in Canada.

Conversely, the other options contain provinces and territories that do not fall within the interior plains. For example, Ontario and Quebec are primarily located in the more densely populated areas of Eastern Canada, which feature different landscapes. Yukon and British Columbia are known for their mountainous terrains and are not classified within the flat characteristics of the interior plains. Similarly, New Brunswick and Nova Scotia are located on the Atlantic coast, featuring different geographic features like forests and coastal landscapes, rather than the vast grasslands of the interior plains.
