C Correct answer
Explanation

Niagara Falls is constantly moving backward (eroding upstream) due to the force of water wearing away the rock. The falls have receded approximately 7 miles (11 km) upstream over the last 12,000 years. This geological erosion process continues today, though rate-control measures have been implemented to slow the recession, making it a landmark that is literally moving backward in position.
