How do rocks influence landscapes?
Students will investigate how local and regional landscapes are affected by properties of underlying bedrock. During the first part of class, they search for and examine local rocks and minerals, determine their properties using geologic tools, and learn the common rocks of the north shore. The geological history of Minnesota is told through the lens of plate tectonics, the rock cycle, rock specimens in our geology museum, and features on geologic maps. During a hike to Marshall Mountain, the class compares the patterns seen in the landscaper to a map of local bedrock types as they discover the geologic history of the north shore and Lake Superior.
