Why don’t trees grow on top of mountains?

 

                   Mountain-tops are usually bare of trees because growing conditions are not suitable for them. The soil is usually very thin on mountain-tops, and the location is too cold and exposed for trees to grow without damage. Some trees can grow there, but they are usually dwarfed and flattened by the wind. Sometimes, although they are trees, they look more like mosses.
