What is the geographical term for a steep, isolated column or pillar of rock that stands in the sea, typically formed after coastal erosion causes the collapse of a sea arch?
💡 Explanation:
A sea stack is a landform resulting from marine erosion. It forms when wave action erodes the base of a headland, creating a sea cave, then an arch, and finally, when the arch collapses, leaving the resistant pillar of rock standing isolated offshore.
