Final answer:
The statement is true; despite wood's insulating properties, lightning can travel through a tree due to the electrical breakdown of resistance caused by the lightning's energy, moisture, and the conducting sap within the tree.
Step-by-step explanation:
The statement, "Although wood is an insulator, lightning can travel through a tree to reach Earth," is true. While it's correct that wood has insulating properties, when lightning strikes, the enormous amount of energy it carries can cause an electrical breakdown of the wood's resistance, enabling the lightning to travel through the tree to the ground. This is because lightning seeks the path of least resistance and the moisture in the tree along with the sap can conduct electricity, making it possible for this natural phenomenon to occur.
