Microsoft Rewards Bing Homepage Quiz Question: Why are these trees called ‘quaking aspens’?
The given options are:
- They grow along fault lines
- The species is anxious
- The leaves tremble
Correct Answer: The leaves tremble
Info: An aspen leaf attaches to a branch by a long, flattened petiole (stem), which causes the leaf to ‘quake’ in the slightest breeze. When all the leaves flutter at once, it may seem as if the tree is shaking, which has inspired many nicknames, such as trembling aspen or quaking aspen.
