evidence: The rocky pyramid-shaped feature in Antarctica is a natural landform called a ‘horn’ or ‘pyramidal peak’. These peaks form when three or four intersecting glaciers carve out mountain faces in different directions, thus making a horn or pyramidal shape. They are common in Antarctica and found in many other places on Earth. Scientific evidence shows that Antarctica slowly drifted to its current position over millions of years through tectonic plate movement; not a sudden shift of the poles or crust.
