Answer :
In a thunderstorm, standing under a tall tree can be dangerous due to the following reasons:
1. Lightning Risk: Tall trees are more likely to be struck by lightning during a thunderstorm because they are the highest point in the immediate area. Lightning seeks the shortest path to the ground, and a tall tree can attract a lightning strike, putting anyone standing under it at risk of being struck.
2. Fall Hazard: During a thunderstorm, strong winds can cause branches to break and fall from tall trees. These falling branches can injure individuals standing below them. Additionally, the tree itself may be weakened by the storm and could topple over, posing a significant danger to anyone underneath.
3. Ground Currents: Lightning strikes to tall trees can also travel through the ground, creating what are known as ground currents. These currents can spread out from the base of the tree, potentially affecting anyone standing nearby. This can lead to electric shock injuries even if the lightning does not directly strike the tree or the person.
Therefore, it is crucial for park visitors to seek shelter in sturdy buildings or designated lightning shelters during a thunderstorm to ensure their safety and avoid the hazards associated with standing under tall trees.
