Lightning from space - level 1
A British astronaut is in space. He is in the ISS. The ISS flies over North Africa, Turkey and Russia. The astronaut films a video. The video shows lightning on Earth. The video is interesting.
Light moves at 300,000 kilometres per second. When a lightning strikes, you see it. However, sound moves slower. You hear the thunder after you see the lightning. You can tell how far the lightning is from you. If you hear the thunder 15 seconds after you see the lightning, the lightning is 4.8 kilometres away.
Difficult words: lightning (the electricity in the sky), strike (to hit), thunder (the noise that you hear after lightning).
You can read the original story and watch the video in the Level 3 section.
