Iceland, so named to discourage conquest by expanding empires, is not at all ice covered like Greenland and parts of Siberia, even though it is not far from the Arctic Circle. The average winter temperature of Iceland is considerably higher than it is in regions at the same latitude in eastern Greenland and central Siberia. Why is this so?
Solution 25E Step 1 Iceland is a terrain where the volcanic activity is high. Geysers are also present in Iceland. Since the volcanic activity is high, the climate will be warm due to the exhaust gas from the inner parts of earth. The warm geysers will keep the atmospheric temperature to a moderate level. More than that, the north atlantic current keeps the Iceland as a warm place during extreme winter. Conclusion The volcanic activities, geysers and north atlantic current keeps Iceland as warm during extreme winter.
