Thunder and lightning occur at roughly the same time although you see the flash of lightning before you hear the thunder. This is because light travels much faster than sound. What Gives Lightning Its Zap? Lightning happens when the negative charges (electrons) in the bottom of the cloud are attracted to the positive charges (protons) in the ...

2023年5月16日 · Thunder is the sound of the pressure wave produced when lightning instantaneously heats air and then it suddenly cools. Thunder and lightning accompany thunderstorms, volcanoes, and heat waves, but have you ever wondered what causes thunder and …

2024年12月5日 · Lightning begins as static charges in a rain cloud. Winds inside the cloud are very turbulent. Water droplets in the bottom part of the cloud are caught in the updrafts and lifted to great heights where the much colder atmosphere freezes them. Meanwhile, downdrafts in the cloud push ice and hail down from the top of the cloud.

2010年3月26日 · Thunder occurs when energy from lightning heats and rapidly expands the air. The resulting sound wave gets heard as thunder. While lightning and thunder occur at roughly the same time, lightning travels at the speed of light, or at 186,000 miles a second, while thunder travels at the speed of sound, equivalent to one-fifth of a mile in one second.

Thunder and lightning are natural phenomena and have nothing at all to do with Zeus, as the ancient Greeks thought. As early as 1752, Benjamin Franklin discovered that lightning was caused by powerful electrical discharges in the clouds. Thunderstorms are caused by small electrically-charged particles. It's quite simple really.

Put simply, lightning is a result of electrons moving between the clouds and the ground, and thunder comes as a result of lightning. Scientists are still trying to work out exactly how lightning forms, but we know it has something to do with the interactions between positive and negatively charged ions within clouds.

One of the most spectacular elements of a thunderstorm is lightning. In fact, it defines thunderstorm, as the lightning causes thunderstorms. Lightning is the discharge of electricity. The single stroke of lightning heats the air around 30,000 degrees celsius. This heating causes the air in the atmosphere to expand very fast.

Lightning can be explained in terms of charges produced due to rubbing. During a thunderstorm, the air currents move upwards and the water droplets move downwards. And this is caused due to the separation of charge due to this vigorous motion.

2018年7月31日 · Inside a thundercloud, cold temperatures and air updrafts provide perfect conditions for lightning genesis. Small, super-cooled droplets of water get carried upwards in the cloud by the updrafts, along with small ice crystals. Blobs of denser soft hail (called graupel) are comparatively unmoved or move downwards.

2002年12月30日 · Thunder is caused by lightning, which is essentially a stream of electrons flowing between or within clouds, or between a cloud and the ground. The air surrounding the electron stream is heated to...
