Show answer & explanation

Correct answer: D

Explanation

The correct answer is Option 4 i.e. lightning is seen before thunder is heard.

Thunder and Lightning
  • Thunder is the sound caused by lightning.
  • Lightning is defined as a flash of light that is caused by the discharge of electricity in the atmosphere.
  • The relation between the two is that lightning causes thunder.
  • Thunder and lightning occur at roughly the same time, although we see the flash of lightning before we hear the thunder.
  • Thus, it can be said that lightning is seen before thunder is heard.
