If you pound a nail into a tree 1 meter off the ground and come back to find it in 20 years, what will it be?

• A. More than 1 meter off the ground and more deeply embedded in the tree
• B. 1 meter off the ground and the same depth in the tree
• C. More than 1 meter off the ground and the same depth in the tree
• D. None of the listed responses is correct.
• E. 1 meter off the ground and more deeply embedded in the tree

Answer: (E)

Verified step by step guidance

1. Understand the concept of tree growth: Trees grow in height from their tips, not from the base. This means that the point where the nail is inserted will remain at the same height over time.
2. Consider the process of secondary growth: Trees also grow in girth due to the activity of the vascular cambium, which adds layers of new cells. This can cause the nail to become more deeply embedded as the tree's trunk expands.
3. Evaluate the options given: Since the nail remains at the same height due to the nature of tree growth, any option suggesting a change in height can be eliminated.
4. Consider the depth of the nail: As the tree grows in girth, the nail will become more deeply embedded, which aligns with the correct answer.
5. Conclude with the correct understanding: The nail will be 1 meter off the ground and more deeply embedded in the tree due to the tree's growth patterns.
