斯堪的纳维亚半岛
The Scandinavian Peninsula occupies part of the Baltic Shield, a stable and large crust segment formed of very old, crystalline metamorphic rocks. Most of the soil covering this substrate was scraped by glaciers during the Ice Ages of antiquity, As a consequence of this scouring, the elevation of the land and the cool-to-cold climate, a relatively small percentage of its land is arable.
