Final answer:
The statement is true; although wood is a poor conductor, the high voltage of lightning can overcome its resistance and pass through a tree to reach the ground.
Step-by-step explanation:
True or false: Although wood is an insulator, lightning can travel through a tree to reach Earth. The statement is true. Despite wood being a poor conductor of electricity, it is not a perfect insulator. In the presence of high voltage, such as a lightning strike, the electrical resistance of wood can be overcome. This allows lightning to pass through the tree to reach the ground. Trees are often struck by lightning because they can provide a path of least resistance for the lightning to reach the earth, especially if they are the tallest objects in the area.
