Question

Quizplus · Accepted Answer

Lightning occurs when there is a buildup of electrical polarity within the clouds, usually caused by the movement of ice and water droplets within the cloud. This buildup of opposing charges results in a discharge of electrical energy in the form of a lightning bolt. Thunder is caused by the rapid heating and expansion of the air surrounding the lightning bolt, which creates a shock wave that we hear as thunder. Lightning is actually quite common on Earth, with an estimated 100 lightning flashes occurring every second around the globe.
