In the US, the Rocky Mountains are a good example of glaciated terrain. A cirque , or bowl-like depression forms at the head of the glacier. After the glacier melts, these depressions often fill with water and form small lakes. Again, these features are common in the Rocky Mountains. For example, the Matterhorn in France.
Aretes are the sharp ridges leading away from horns.
Generally form from fringing reefs that surround volcanic islands. As the island subsides or is eroded away it leaves the lagoon and reef forming the atoll. Wave erosion and sediments carve-out these features, often creating sea caves or sea arches. The coast of northern California has many of these features as do portions of the Japan coast in northern Honshu. At this point we will take a look at some selected landforms.
