Q: What is the tree-line?

Q: What are the different types of tree lines?
A: The main types of tree lines include Arctic, Antarctic, Alpine, Exposure, Desert, Toxic and Wetland.
Q: What climate exists above the tree-line?
A: Above the tree-line exists an alpine climate characterized by cold temperatures and snow cover throughout much of the year.
Q: How does wind affect the lower elevation of some tree lines?
A: In coastal areas and isolated mountains, high winds can reduce tree growth so that trees only grow at lower elevations than in larger mountain systems with more protection from windy conditions.
