Extreme Earth – Thunder Storms

Thunder and Lightning

Lightning-ThunderLightning is electricity. In effect, positive charges and negative charges collect in different parts of a cloud — no one really knows exactly how. When enough charges collect, there is a bolt of lightning as the electricity travels between areas of opposite charge. Lightning can flow between clouds or from the cloud to the ground. The lightning jumps through the air, heating the air and making it expand. The air then quickly contracts again as it cools. This movement of air makes the sound wave called thunder.  Thunder storms are not uncommon in late summer in this country but in warmer parts of the world they are much more frequent and can be a real problem. There are several interesting videos to help teaching about thunder storms and lots of sites have sets of interesting facts!
