The Four Welland Canals
How Ships Climb A Mountain
Geo, do you know why people built
the Welland Canal ?
Sure. Ships could not use the
Niagara River. The Niagara Falls were the 'obstacle'. You can see it all
on a relief map of the Niagara Peninsula.
From the information in the Canal
Profile diagram below, we can calculate the height of the mountain the
ships have to climb.
