During the Ice Age did glaciers erode away any of the earth’s surface

It certainly did; glacial erosion is very characteristic and geologists can often tell at a glance whether a landscape has been glaciated.In the UK the ice reached as far south as the Thames/Severn rivers and there is a marked difference in the landscapes between northern and southern England. In the south, river valleys are V shaped – created by the erosion of rivers, in the north valleys are usually U shaped; glaciers have eroded the sides of the valleys – any V shaped valleys are relatively modern.The mountains of Scotland are rounded – again from glaciation.
