Question

A tree grows about one-foot each year. you carve your initials into the trunk of a tree that is 15 feet tall. your initials are four feet above the ground today. How far above the ground will they be in 10 years? why?

Answer 1

The initials will still be 4 feet above the ground.

Trees do not grow from the bottom up. At the branch tips there is meristem tissue, so called the apical meristem. Trees grow in height from these apical meristems, so trees grow from the top and the initials on the bottom of the tree will stay at the same height above the ground.
