A Correct answer
Explanation

Niagara Falls is gradually eroding backward due to water flow, receding about 1 foot per year. The falls have moved approximately 7 miles upstream from their original location over thousands of years. This natural erosion process continues, though modern flow control has slowed the rate. The question uses poetic phrasing about 'constantly moving backward.'
