How do landforms link the geography of canada and the us

St. Lawrence River, the Great Plains, and the Rocky Mountains are major landforms that both Canada and the United States of America share.  You could also say the great lakes. Hope I helped.     : )

Aristotle thought so every portion of the earth tends toward the center until by compression and convergence they form a sphere. travelers going south see southern constellations rise higher above the horizon.~ hope this !
