During cold periods of Earth’s history, glaciers carved channels into the volcanic rocks from which the islands were originally formed. As the Earth warmed and sea level rose, these channels became the long, deep, steep-sided inlets that now line the eastern coast of Auckland Island.

Glaciers are not landforms. It is the action of glaciers that creates landforms. The process is known as glaciation.

How might evidence for glaciation around the globe also provide evidence for the movement of the continents?
