MAJOR GEOGRAPHIC FEATURES
Quebec is made up of 3 regions. One is the Canadian Shield that makes up 90% of Quebec. It is composed of granite. The southern part forms a major subdivision called the Laurentian Highlands which is 968 miles (3,176 ft.) atop Mountain Fremblant. Low temperatures have caused permafrost in the northern quarter of the Canadian Shield area in Quebec. One of the other regions is the Appalachain Region that is made up of parallel ridges of molded and eroded sedimentary rocks. Notre Dam Mountains are the chief mountain system of this region. Glacial sands and clays fill the deep valleys. The last region is the St. Lawrence Lowland. It is a heavily populated area lying between the Canadian Shield and the Appalachain Region. It is underlaid by limestone and covered by marine clays and glacial sands. The Monteregian hills are part of this lowland and are located around Montreal. The highest peak is Brome Mountain. This lowland contains good farmland. Quebec has many rivers and lakes. St. Lawrence River is 1,900 miles long. Other main tributaries found in the North are Ottawa, Saint Maurice, Saguenary, and Manicougan. Other rivers found in the south are Richelieu, Saint Francois, and Chaudiere. Some streams found in Quebec are Eastmain, Nottaway and La Grand River.
