North America's terrain includes: two major mountain systems--the Rockies in the West and the Appalachians in the East; the Great Plains; the five Great Lakes; the Mississippi River; Canada's huge Hudson Bay Hudson Bay, inland sea of North America, c.475,000 sq mi (1,230,000 sq km), c.850 mi (1,370 km) long and c.650 mi (1,050 km) wide, E central Canada. Hudson Bay and James Bay (its southern extension) and all their islands border Nunavut Territory, Manitoba, Ontario, and Quebec. Hudson Strait (c.450 mi/720 km long) connects Hudson Bay with the Atlantic Ocean, and Foxe Channel leads to the Arctic Ocean.; and deserts, massive plateaus, plains, and tropical rain forests.
