If the potential difference is great enough, lightning will strike the object or the ground. Lightning can seriously damage trees, houses and other structures that it strikes. The high temperature of a lightning bolt can easily set a building on fire. The force of a lightning bolt can shatter the trunk of a tree. The extremely high voltage of a lightning bolt can cause metal to melt.
From National Lightning Safety Institute. If lightning strikes someone, it can easily kill the person. There are about 60 deaths a year in the United States due to lightning strikes. Cambodia has a much higher fatality rate, with 75 people being killed in Lightning strikes injure about people in the U. The greatest benefit of lightning is that it separates Nitrogen from the air, providing natural fertilizer to the ground below. Each year, 10 million tons of nitrogen are deposited into the Earth.
Lightning also causes forest fires which are essential in rejuvenating the forests and getting rid of old growth. Lightning is an amazing natural phenomenon. Use it to discuss the nature of electricity, charge and the transfer of electrical energy into heat, light and sound. Planet Science. Advanced Search. Under 11s. Over 11s. Over 11s Natural world.

Someone complained about a teacher using this question and the answer was disputed. After some time, the teacher claimed that the answer was that lightning is static electricity because she looked it up on the internet. So, I decided to look also, here is what I found searching for "what kind of electricity is lightning? Here they define current electricity as a steady flow of electrons.
If they use this definition, then maybe lightning is static, but then what would household current be which is AC and therefore not steady. I would define static electricity as non-moving electrons static - doesn't that make sense. When you rub the balloon on your head, the electrons build up on one side with the protons on the other. You can see the two pulling towards each other as you pull the balloon away from your head.
You hair stands up and reaches toward the balloon! The metal spoon is a conductor. A conductor is an object that electricity can easily move through, from atom to atom.
When we bring the spoon down to touch our negatively charged balloon, the electrons jump to meet the protons. In nature, bits of ice bump each other and collide up in the clouds. As they collide, they build up static electricity, with positively charged particles at the top of the cloud and negatively charged particles at the bottom.
