Question

The age of a tree is best approximated by

A) estimating tree height.
B) counting tree growth rings.
C) measuring the diameter of a trunk at breast height (dbh).
D) counting the number of leaves.

Answer 1

The age of a tree is best approximated by counting tree growth rings through the technique of dendrochronology.

Step-by-step explanation:

The age of a tree is best approximated by counting tree growth rings. Tree rings develop annually and vary in width depending on the quantity of nutrients and water available each year. Scientists use a technique called dendrochronology to count the rings and determine the age of a tree.
