According to the World Atlas, the major landforms of Quebec are plains, plateaus, coniferous forests, rivers and lakes. Most of Quebec is covered by the Canadian Shiels, a rocky but level landscape of plains and plateaus. The province contains over a million lakes and thousands of rivers and streams.
Quebec is Canada's largest province and is more than twice the size of Texas, according to the World Atlas. In northern Quebec is the tundra, a mostly level, treeless landscape with a permanently frozen subsoil. In the far north lie the Torngat Mountains; Mount D'lberville is Canada's highest point, standing at 1,625 meters. While the Torngat Mountains in the north are treeless, the Laurentian Mountains in the south are covered in dense forests. Both mountain ranges contain lakes and rivers.
Apart from mountain ranges, the World Atlas cites Quebec's Gaspe Peninsula as a major landform. It extends into the Gulf of Saint Lawrence and contains part of the Appalachian Mountains. The St. Lawrence River is the most famous river in Canada. It links the Atlantic Ocean with the Great Lakes, making it Canada's most important economic highway. The St. Lawrence Seaway is a system of canals in and along the river that grants ocean vessels access to the Great Lakes.
