Question
Imagine that you pounded a nail into the trunk of a tree in your grandparents' yard as a child. Thirty years later you recall pounding the nail and find that the nail is still in the trunk. A) Would you expect to see that the nail had gained height as the tree grew over those 30 years? Or would the nail have just moved laterally (away from the center)? Or would you expect the nail to have moved in both directions? You'll need to justify your answer by discussing how B) primary growth and C) secondary growth works in trees. Sadly, you get word that the tree has become hazardous by growing too close to your grandmother's home. An arborist cuts it down and then you return to see the trunk. While looking at the growth rings, your grandmother tells you that 50 years ago there were three years in a row of severe drought, and asks if you can find evidence of the drought in the tree rings. D) What kind of rings would you tell your grandmother to look for and why?
