Electricity

How is lightning formed???

First thing is the sky is filled with electrical charges. Electric charge is spread out, and it is most likely not equal. The positive charge is at the top of the clouds, and the negative charge is at the bottom. Once the negative attraction gets close to Earth (which has a positive attraction) a flow of negative charge rushes toward the Earth. The positive charge follows after, since it is attracted to the negative charge. When the positive charge meets the earth's surface, a strong electric current carries positive charge into the cloud. That is visible to the human eye and is known as lightning.

elecrricity is formed when positive and negitive electrons come together and form a spark and in life the earth is the negitive electrons and the sky is the positive\

In most rain clouds, the bottom of the cloud is negatively charged. And the top of the cloud is postively charged. Ice inside the cloud is the key element in how lightning develops. The collisons within the tunderstorm can cause the electric particles to build up and create the lightning also.

electrical charges in the sky are mixed together and they make lightning

Lighting is formed because the sky is full of negatively and positly charged pariticles. When storm clouds collide then they will will meet and more then likley there will be more negative or positive. THe earth has a positive attration so all the negative and positive will be attract and if enough of the charges are present then they come down to earth in a lighting bolt.

Lightning is an atmospheric discharge of electricity, that usually occurs during thunderstorms, and sometimes during volcanic eruptions or dust storms. How lightning is actually formed is still a matter of debate. Scientists have studied the causes ranging from atmospheric perturbations to the impact of solar wind and accumulation of charged solar particles.

Lighting is formed when positive and negative electrons come together and form a spark and ii creates lighting and you can harness the lighting to make electricity.

THe sky fills with electrical charges. Their are positive and negative charges. THey meet and go to eath in lightning forms.

Lighting is formed by electrical charges in the sky. When electricity is spread out the positive charge is at the top of the clouds and the negative is at the bottom. When the negative attraction gets close to earth the negative and positve charges react and causes a bright light reaction.

In clouds there are eletrical charges that are all over. There are two different charges in the cloud though, positive on the top and negative on the bottom. The lower the cloud is to the Earth, the stronger the attraction between the particles and Earth. The negative particles are attracted to the Earth because Earth has a postive charge and since it is so big it has a big attraction with the particles in clouds. When the negative particles rush down, the postive particles follow with them causing lightening.

Lightning is formed by all the electrical charges that are all over in the sky. The electric charge is spread out and is not equal in every spot. In the clouds, the positive charges are on the top and the negative are on the bottom. When the positive charge hits the earth's surface, the electric current brings it into the cloud. Then it is lightning.

The sky is filled with positive and negative charges. The positive charges are usually at the to pand the negative charges are usually at the bottom. WHen these charges come together in the cloud there is usually ice and the charges cause lightning to form. That is pretty much how lightning forms.

Lightning is formed when cold and warm air meet. The warm air goes up and makes thunderstorm clouds. It has water droplets, which bump crystals in the air during a storm. This rubbing makes static electric charges. The cloud has positive (top) and negative (bottom) sides. When the charge gets strong at the bottom, the cloud releases energy. This energy is a lightning bolt and goes to where it is an opposite charge. The bolt actually goes back up to the cloud, which heats the air, which spreads quickly. This makes thunder.
