  2. Trees and buildings may fall causing damage,

  3. Trees and buildings do not offer enough escape ground,

  4. None of the above,

Show answer
Correct Option: A
Explanation:

Sometimes electric discharge can take place between the charged cloud and Earth. While passing over a tree or a tall building an opposite charge may be induced causing a lightning to strike the tree or a building and if the charge is large it may cause severe damage and may prove to be fatal. Thus, it is advised to stay away from tall buildings or tree during thunderstorms.

  1. Lightning may strike a building due to opposite charge causing fir or damage to the building

  2. In the rainy season water increases the chances of lightning striking a building causing damage

  3. Both A & B

  4. None of the above

Show answer
Correct Option: B
Explanation:

Sometimes electric discharge can take place between the charged cloud and earth. While passing over a tree or a tall building an opposite charge may be induced causing a lightning to a building and if the charge is large it may cause severe damage and may prove to be fatal. In the rainy season water being a good conductor of electricity increases the chances of lightning striking a building.
