Question

Why shouldn’t one stand under a tree or a tall building during a thunderstorm?
A. Lightning can strike trees and buildings.
B. Trees and buildings may fall causing damage.
C. Trees and buildings do not offer enough escape ground.
D. None of the above.

Answer 1

Hint: Thunder is resulted because of lightning. Lightning is attracted to the tallest objects. Trees and buildings are sometimes the tallest objects in nature. Humans have more ions than trees so we shouldn’t stay near trees or buildings as we will be better conductors than them.

Complete step by step answer:
Clouds have water molecules and they collide which means clouds have charged particles. Positive charges move to the top of the cloud and negative settles at the bottom of the cloud. As we know the clouds are constantly moving, so when they pass over a tree or a building the negative charges of the cloud and positive charges from the earth may produce an electric current or the ions in the clouds may collide to produce electric currents which cause lightning.Trees have ions as well as Human beings also have ions. Lightning is a result of electrical charges. And lightning occurs mostly on tall objects.Trees and Tall buildings are mostly tall objects in nature. Therefore, trees will be the targets. As trees do not contain many numbers of ions as much as we do, therefore humans are better conductors than trees and buildings. So lightning when struck by trees can jump to humans easily.The surroundings around the lightning area experience an increase in temperature and pressure. Therefore, the air expands in which the expansion makes the sound during thunderstorms. Therefore, one should not stand near a tree or a tall building during a thunderstorm because Lightning can strike trees and buildings and further it can jump to humans easily.
The answer is Option A.

Note: Lightning is a giant spark of electricity in the atmosphere between clouds, the air, or the ground of the earth. When two oppositely electrically charged regions are combined they release a lot of energy nearly one gigajoule of energy causing the lightning which can kill humans in some milliseconds.
