Question
How are the shapes of crowns of trees, and their location on earth, related to each other?
Answer
The shape of the crowns of trees has a lot to do with where it is located. If a tree is located nearer to the equator, then tall trees, with flat treetops (or crowns), are very common in this part of the world.
If a tree is located near the Arctic circle, the sun is never directly overhead and is usually quite low in the sky. Trees, in this part of the world, tend to be cone-shaped.
