What are the three highland landform regions found in Canada?

The three highland landform regions found in Canada are indeed the Western Cordillera, the Innuitian Mountains, and the Appalachian Mountains. Each of these regions has distinct geological characteristics and formations that classify them as highland areas.

The Western Cordillera is a series of mountain ranges that stretches from British Columbia to the southern United States, characterized by rugged peaks and deep valleys. This region is home to some of the highest elevations in Canada, including the majestic Rocky Mountains.

The Innuitian Mountains are located in the Arctic region of Canada and are known for their extreme, rugged terrain. These mountains are primarily composed of sedimentary rock and have been shaped by glacial activity, which is typical in this frigid environment.

The Appalachian Mountains, though older and more eroded than the Rocky Mountains, are significant highlands in the eastern part of Canada, extending from Newfoundland to the United States. They played a crucial role in the geological history of North America and are recognized for their rolling hills and valleys.

The other options include regions that do not fit within the highland classification, such as the Interior Plains or the Canadian Shield, which are characterized by flat land and larger sedimentary deposits rather than mountainous terrain. Therefore, the selection of the Western Cordillera
