tundra+abiotic+factors+p.6

__** Abiotic Factors **__  Some abiotic factors of the Tundra Biome:
 * Little Rainfall
 * The top layer of soil thaws only during the summer
 * Temperture
 * Seasons (Long Winters, Long Summer, Short Spring and Fall)
 * Altitude
 * Mineral Composition ( How likely it is for an animal to have the resources to grow there)
 * Wind
 * Terrain


 * __Weather__**- The average annual temperature is about -18 F. The average temperature in the summer is from 37 F to about 60 F. The nights in the tundra can last for a long time in the winter and can get down to -94 F The wind speed can get as high as 60 miles per hour. The tundra only gets 6-10 inches of rain a year, it is like a desert in that aspect but a lot colder.

Example on how different the Tundra Biome can get with the different seasons!!!
 * __Landscape__**- The tundra is a very dry and barron place, it does not have any trees and is a huge area. The ground is frozen from 10 inches to 3 feet down so nothing can grow there. There is also not a lot of sunlight for plant to grow in the winter. In the summer, when the permafrost melts, the tundra turns into a place with a lot of lakes and bogs.
