Skerry

A skerry (Swedish skär; norwegian skjær or skjer ) is a small island, formed in the Ice Age, when the light emanating from Scandinavia and North America, ice flowed over the underlying rock masses and sanding. Thus made ​​her flat, rounded shape. You can be great a few square meters to several square kilometers. Archipelago are used primarily in Scandinavia and Canada before, often in groups as a so-called archipelago (Swedish skärgård, Danish Archipelago ).

Scientifically considered (see geomorphology ) include the archipelago, together with the larger, but lush vegetated bars to the round bumps. Like the coastal archipelago (also Fjärdenküsten ) also emerged the fjords during the ice ages. The defrosting of the ice masses freed from the weight of the ice masses of rock emerged in the form of many small islands only during the last 10,000 years out of the sea. Today, the country stands still, so that the islands continue to grow.

Extensive European archipelago landscapes there on the coasts of Norway, Sweden and Finland ( Turku archipelago ) as well as in larger lakes in these countries (eg Mälaren, Vänern ). Here the larger islands are often inhabited. Outside Europe there are warping landscapes, especially on the Atlantic coast of Canada and the Hudson Bay ( northern Canada ). Archipelago rarely rise more than 50 meters above the sea and are depending on location, climate and wind conditions with grass, bushes or low trees overgrown. On the mainland side of the archipelago landscapes often are sheltered harbors and waterways, but the navigation is there as a result of many shoals often challenging.
