Answer Details
The best word(s) or phrase(s) to fill the gap is "erode".
Explanation: The verb "erode" means to gradually wear away or destroy a surface by natural processes such as wind, water, or ice. In this sentence, the sea waves are causing the cliff on the west coast to wear away or be destroyed gradually over time. This gradual wearing away of the cliff is a result of the constant action of the sea waves, so "erode" is the most appropriate choice to fill the gap.
