What is Lightning?
==== Lightning is strong air currents that bounce water droplets and pieces of ice up and down inside the cloud. These collide and rub against one another. The rubbing creates a force called an Electrical Charge. The cloud is now charged with electricity. There are possitive charges at the top of the cloud with negative at the bottom. The negative charges attract the possitive charges and a giant spark of electricity goes between them. You can see this spark as a flash of Lightning. The Lightning may also flash between the cloud and the ground. ====

What is a Tornado?
==== Tornadoes are twisting funnels that develop over land. These violent whirlwinds form where warm, moist meets colder drier air flowing in from another direction. A twisting column of air streches from storm clouds down to the ground. Like hurricanes, they have a central area of low pressure, around which powerful winds rush in spirals.It is not only the winds that cause damage. The low-pressure centre of the tornado can cause buildings to explode, as pressure inside the buildings is so much greater. ====
