Tundra is described as an area where levels of subsoil beneath the surface of the earth are permanently frozen. This soil is
referred to as permafrost. The level of earth above the permafrost will thaw in the
short summer allowing plants to grow. This level will then freeze again in the winter
and most of the plants will go dormant.
Permafrost makes it difficult or impossible for trees to root down into the ground, so one of the characteristics of
tundra is that it is often treeless and the land appears barren. Another characteristic
of tundra is that it, like deserts, receives little precipitation. Tundra will also reach
extremely frigid temperatures, especially in the winter when it receives little to no
Tundra has two variations, Arctic Tundra and Alpine Tundra. Arctic Tundra can be found near or north of the Arctic circle around the north pole. Alpine Tundra can be found at various latitudes on earth but is located at high altitudes on mountains where trees do not grow.
