The landforms of Quebec fall into three main regions: the St. Lawrence Lowlands, the Appalachian Highlands and the Canadian Shield. There are also some smaller landforms such as the Laurentian Mountains, the Torngat Mountains and the Monteregian Hills.
The Canadian Shield is Quebec's most prominent landform. The plateau stretches over nearly 80 percent of the province, starting at the city of St. Lawrence and moving northward. It contains boreal forests, tundra, rivers and lakes. The Laurentian Mountains and Torngat Mountains lie on the Shield. The Laurentians start in central Quebec and run north. With an elevation between 2,000 and 4,000 feet, this ancient mountain range is covered in forests.
The Torngats run northeast between Quebec and the Labrador province. These mountains culminate in Mount Caubvick, the highest point. Although the Torngats have no trees, it does have many fjords. The Appalachian Highlands are part of Appalachian Mountain chain that extends between Maine and Quebec.
The St. Lawrence Lowlands dip down from the Shield diagonally across the province, extending on either side of the St. Lawrence Seaway. This fertile land serves as not only the agricultural hub of the province, but the population center as well. The lowlands rise up into the Monteregian Hills, flat-topped buttes that hover 800 feet above Montreal.
