What is the isolated standing rock left after a sea arch collapses called?
Answer and explanation
Correct answer: Sea stack
The correct answer is Sea stack. Waves continue to enlarge cracks and weaken the roof of a sea arch. Eventually the arch roof collapses, leaving a separate vertical pillar of resistant rock standing offshore; this remnant is called a sea stack. Later erosion may reduce it to a lower stump. A sinkhole is a karst or collapse depression, a meander is a river bend, and an esker is a sinuous glacial deposit, so none matches coastal wave erosion.
