(DESCRIPTION)
Title, Myth vs Reality. Text under Myth, Volcanoes on land exist only in hot climates.
 
Text under Reality, Volcanoes can form in any climate. The Eyjafjallajokull volcano resides in the subarctic climate of Iceland, for example, while numerous volcanoes exist under the ice in Antarctica. Earth's continents are part of massive slabs of rock known as tectonic plates, which are in continuous motion. Most volcanoes form along plate boundaries, where the plates collide or spread apart, but some form far from plate boundaries in places known as hot spots. Plate boundaries and hot spots are independent of climate zones.
