Answer:
Thunder
Step-by-step explanation:
Lightning is caused by rapid expansion of the air surrounding its path. It takes only a few thousandths of a second for a lightning bolt to travel from the clouds to a nearby tree. Temperature rises rapidly, resulting in a rapid rise in air pressure of 10 to 100 times the normal level. Thunderbolts travel vertically, following the shortest route. You hear the shock waves closer to the ground first, then the shock waves higher up. A long rumble may be heard from vertical lightning.
