Lighting strikes form the air and the ground at the same time. When the two electrical charges meet in the middle it gives off a huge flash in mid air and can be very harmful if hit upon by it, but it can also be very relaxing to sit out outside and watch the two things hit. Some people take pictures and do research on them.

Also lightning is an atmospheric discharge of electricity accompanied by thunder.
ReplyDeleteYou need cold air and warm air. When they meet, the warm air goes up. It makes thunderstorm clouds! The cold air has ice crystals. The warm air has water droplets. During the storm, the droplets and crystals bump together and move apart in the air. This rubbing makes static electrical charges in the clouds.
ReplyDeleteLightning is an atmospheric discharge of electricity accompanied by thunder, which typically occurs during thunderstorms, and sometimes during volcanic eruptions or dust storms. In the atmospheric electrical discharge, a leader of a bolt of lightning can travel at speeds of 60,000 m/s (130,000 mph), and can reach temperatures approaching 30,000 °C (54,000 °F), hot enough to fuse silica sand into glass channels known as fulgurites which are normally hollow and can extend some distance into the ground There are some 16 million lightning storms in the world every year.
ReplyDeleteLightning can initially be formed by condensed water in clouds freezing into hail, then being blown by wind. The wind smashes the hail together, separating positive and negative charges. When enough negative charges build up, lightning is formed and strikes the tallest object near it.[citation needed]
