Multiple choice

What causes lightning?

  1. Lightning is caused by the build up of electrostatic charge in clouds.

  2. Air is a bad conductor, but the presence of different impurities and impure water drops makes air partly conductive. It causes sparking from high tension wires which we perceive as lightning.

  3. Condensation of water in the clouds causes sparking due to release of energy which we perceive as lightning.

  4. When air blows, clouds collide with each other, which causes sparking due to friction, which we perceive as lightning.
