The most significant physical feature that forms Canada's boundary is the sea. Canada has the longest sea coast in the world. Canadian territory also extends far into the sea. The next most significant physical feature that forms Canada's boundary (and it pales by comparison) is the height of land between Québec and parts of Maine and New Hampshire. Except for the height of land in Quetico Park, the remaining significant physical features are only physical in part: an artificial line drawn through much of the Great Lakes and connecting waterways; and a similar artificial line drawn through the Rainy River watershed and through Lake of the Woods.
One of Rio de Janeiro's most prominent physical features is Sugarloaf Mountain.
