There are three types of lightening, There is Ground-to-cloud, Cloud-to-ground and cloud-to-cloud.
Lightning typically comes from the elctrical static in clouds. However it can also come up from the ground and intermingle with a bolt of lightning coming down from the clouds. But mostly from the clouds above.Sandman
i think that electricity starts from the ground
Lightning travels both up and down. It typically originates from the ground and travels upwards to meet the downward-moving charge from the clouds. This forms a visible lightning bolt.
Lightning typically strikes from the sky down to the ground.
the charge of a lightning is positive and negative. The positive is on the top of a lightning cloud and the negative is surrounded on the bottom. As it flashes down it is a negative. However, the ground is a positive charge so as it reaches down, it turns into a positive charge. I hope this will answer you question
Actually it does BUT it also comes down from the clouds. Now A positive charge is sent up when the negative charge is sent down. They meet but we only see the one sent up because it is slower.
No, lightning strikes from the sky down.
No, it doesn't need to rain for thunder and lightning to occur because the thunder and lightning need cold and warm air so they collide. The clouds are like big batteries and the lightning is the short circuit. also the lightning can be between the clouds and it doesn't strike down to the ground. also if the clouds have temperature conditions and it doesn't have to rain it just creates thunder and lightning.
Lightning can strike upwards, from the ground to the sky, and it can also strike downwards, from one cloud to another, or from one part of a cloud to another part. (see: http://www.answers.com/topic/lightning)
Electricity is the transfer of electrons between molecules; for example, a battery sends these tiny particles from its negative end to its positive end. If an electrical current does not have a sufficient "load," or job to perform, along its path then it short-circuits and makes a popping noise accompanied by intense heat (which was the electrical energy that went unused and had to be disposed of somehow). The earth and its atmosphere are essentially a gigantic battery; when a path is formed in the air which can carry a current, the battery shorts and we call the resulting flash lightning.To answer the original question, however, it typically starts in a cloud, but 5-10% of lightning strikes start in the ground. It should also be noted that the above explanation is somewhat oversimplified. For more details, see the related links.No, lightning can not start from the ground, it forms inbetween or in a cloud and starts coming down when its closer to the ground there is a charge that causes it to also start coming up from the ground to meet the first part, the part coming up from the ground comes much slower though. If there is a flicker that is just the upward stroke repeating the process.
Lightning typically travels from the sky to the ground. It is initiated by a downward-moving stepped leader from the cloud that is met by an upward-moving streamer from the ground, creating the visible lightning bolt.
When lightning strikes in a cloud, it creates a path of ionized air, allowing the negative charges in the cloud to flow to the positively charged ground. This discharge of electricity neutralizes the charge separation between the cloud and the ground, resulting in the visible lightning strike and thunder.
