Elizabeth (9) asked a question on lightning

Elizabeth, thank you for your question. “How many %C is the air surrounded by lightning?” I am sorry that I had a difficulty in understanding it. Are you asking about the temperature (degrees C) or are you asking about the Carbon (C) in the air ?  As it was a question about lightning I thought I could ask my friends to talk about that. If you want to revise your question you can easily ask it again. lightning-strike

Thanks team, some very interesting observations.

What I find interesting is how does lightning happen. It’s all about clouds. Hot weather produces lots of evaporation of water from our oceans. The hot air and water mixture rises, look at the clouds from a kettle. As it rises, the cloud of water vapour and air gets colder, and colder. The water turns into very small ice crystals which are still lifted by the cloud of air that they are in. As this happens it is thought that the ice particles separate ……. the lighter particles move to the top of the cloud while the heavier particles remain at the bottom.

The water/ice particles have a small electrical charge associated with them. When they separate the charge moves with them. It is likely that this causes an uneven redistribution of the total electrical charge. If you have more lighter water/ice particles at the top of the cloud than heavier ones at the bottom the difference in the total charges could be significant. So ‘flash’ they try to equalise and thus the lightning flash. It’s the process of the ice crystals at the top of the cloud trying to get rid of their excess electrical charge by giving it to the heavier ice crystals at the bottom of the cloud.

Sometimes difference in charge is so great that the ‘flash’ continues to the ground, but if you are in a storm and look at the flashes a lot of them are within the clouds themselves.

Elizabeth, sorry for such a long explanation. It was such an interesting question. If you have any other questions linked to what my friends and i have said please ask them.

Elizabeth. Some additional information ……. Look at this site. The type of electricity that is built up in clouds , before the lightning flash is static electricity. There are some experiments you could try.
