ken's differences between the tundra and the tropical forests

The main  differences between the two climates is not enough rain in tropical wet and dry climates to support rain forests. Tundra climates are dry, with a brief, chilly summer and a bitterly cold winter.Tundra is located on earth's poles, which receive little sunlight making it extremely cold. Little vegetation can become established because of the permafrost that prevents root systems, as well as the winds that clear miles of open land.
