Raging Rapids: The Power of Water Video |
Witness the Forces that Created Niagara Falls |
Students can watch as the walls of the Niagara Gorge give up the secrets of Earth's history that are embedded in them. Born just 12,500 years ago after the last glacial surge, Niagara Falls has been slicing through seven miles of riverbed for thousands of years, opening up a gorge rich with geological history. Then students will consider the possibility that the power of the raging falls is now threatening its very existence. Closed-captioned. Duration: 26 minutes.
