Final answer:
True, lightning can travel through a tree to reach the Earth. Burning pressure-treated wood should be avoided due to potential health risks.
Step-by-step explanation:
True. Lightning can indeed travel through a tree to reach the Earth. Although wood is generally considered an insulator, under certain conditions, such as during a lightning strike, it becomes a conductor of electricity.
When lightning strikes a tree, the high voltage of the lightning can ionize the moisture inside the tree, creating a conductive path. This allows the electrical current to flow through the tree and into the ground.
It's important to note that while burning pressure-treated wood is technically possible, it should be avoided. Pressure-treated wood contains chemicals, such as arsenic, that can be released into the air when burned, posing health risks. It is safer to dispose of pressure-treated wood properly through appropriate waste management methods.
