Tundra is, according to the good folks at HowSutffWorks, "a treeless region located in the Arctic or at high altitudes. Tundra occurring in the Arctic is known as arctic tundra, that at high altitudes is called alpine tundra. Both types are relatively flat, and they have similar climates and vegetation. The main difference between the two, besides location, is that permafrost (permanently frozen ground) underlies virtually all of the arctic tundra but is rare in alpine tundra."
