問題詳情

【題組B】Lightning and ThunderLightning is a streak of electricity that occurs in every thunderstorm. Although lightning and thunder occur at the same time, you see lightning before you hear thunder because light travels faster than sound. Lightning and thunder are caused when the negative charge of electricity in the rain clouds meets the positive charge of electricity in the falling raindrops. Most lightning occurs from cloud-to-cloud, but some lightning occurs from cloud-to-ground, where it can start fires, melt metal, or be deadly to people. Although 90% of people survive lightning strikes, they can cause major internal injuries, burns, and hearing loss.Did you know you can calculate the distance of lightning from its thunder? We see lightning before we hear thunder because light travels much more quickly than sound. If you see lightning in the sky and hear thunder five seconds later, the lightning is about one mile from your location.lightning閃電 thunder雷聲 streak條紋;光線 electricity電 occur發生;出現 thunderstorm大雷雨 travel行進;旅行 is caused發生 the negative charge of electricity負電荷 the positive charge of electricity正電荷 raindrop雨滴;雨點 start fire起火 melt metal熔化金屬 deadly致命的 survive在...之後仍然生存 lightning strike雷撃 cause造成;導致 major重大的 internal體內的 injury傷害;損傷 burn燒傷 hearing loss聽力喪失 calculate計算 distance距離 location地點;位置
