Final answer:
The statement is true; British Columbia, the Yukon Territories, Nunavut, and the Northwest Territories constitute the western and northern lands of Canada, encompassing both provinces and territories with various geographical features.
Step-by-step explanation:
The statement that the western and northern lands of Canada include the provinces of British Columbia, the Yukon Territories, Nunavut, and the Northwest Territories is true. British Columbia is a province on the west coast of Canada, known for its natural beauty and resources such as from its mining and lumber mills. The Yukon Territory, Nunavut, and the Northwest Territories are regions to the north, with Nunavut having separated from the Northwest Territories in 1999 to become its own territory. Together, these areas make up a significant portion of Canada's landmass and are characterized by diverse physical geography, including mountain ranges and remote, sparsely populated territories.
