When lightning strikes in a cloud push down on the negative charges in the g round?
no it go through the clouds and strikes
Where in the atmosphere does lightning occur?
Negative charge accumulates on the bottom of a cumulonimbus cloud and becomes attracted to the positive charge of the ground. When it overcomes air resistance, the charges shoot down. The lightning that you see is when the positive charge shoots back up into the cloud.
Why is ground possitively charged?
because oppisites attract. The power from the plants below the cloud pull the - charges down and the + charges goes up and that also causes lighting wow im 12 and i know this
Does lightning go up?
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)
Why is clouds upper part possitively charged and bottom part negetively charger?
because oppisites attract. The power from the plants below the cloud pull the - charges down and the + charges goes up and that also causes lighting wow im 12 and i know this

Does lighting form with positive or negative charges?
The lighting is always a negative charge, but it can flow both from the clouds and down, as well as from the ground and up.
Does lightning start from the ground and go up or start from the clouds and go down?
There are three types of lightening, There is Ground-to-cloud, Cloud-to-ground and cloud-to-cloud.

Is fog a stratus cloud close to the ground?
yes all it is is a big cloud that floats down to the ground
What is charge of lightning?
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

What do you call a lightning bolt coming from the ground?
Lightning is an electric current. Within a thundercloud way up in the sky, many small bits of ice (frozen raindrops) bump into each other as they move around in the air. All of those collisions create an electric charge. After a while, the whole cloud fills up with electrical charges. The positive charges or protons form at the top of the cloud and the negative charges or electrons form at the bottom of the cloud. Since opposites attract, that causes a positive charge to build up on the ground beneath the cloud. The grounds electrical charge concentrates around anything that sticks up, such as mountains, people, or single trees. The charge coming up from these points eventually connects with a charge reaching down from the clouds and hit the highest point. There isn't any lightning that originates from the ground.
Is lighting ground to sky or from sky to ground?
There is much confusion over the "up" or "down" motion of lightning bolts, but in most cases it is initiated by the flow of negative ions in clouds to a positively charged point at another point (cloud or ground). What is referred to as "lightning" is a luminous path of superheated air caused by repeated current flows from the ground and the air. In certain cloud types, the interaction of ice and water (and possibly the Earth's magnetic field) creates a surplus of negatively charged particles, usually near the bottom of the cloud. Where the ground and objects below have accumulated positive charges, an electric discharge can occur. This is preceded by "step leaders" moving down from the clouds and "positive leaders" moving up from the ground. Where these streams come in contact, the negative ions flow to the ground, followed by a return flow of positive ions. This can occur multiple times in the same lightning strike.
How does thunder and lightning work?
Lightning is a discharge of electrical energy that builds up within a storm. The charges develop because a storm causes air to move around which rubs against itself to generate electrical charges. Eventually the charge increases to a point where the electricity can flow through the air. Once an electric discharge starts it provides a better path for more electrical flow than normal air due to ionization which results in a sudden, large and fast discharge (i.e. a lightning bolt).Negative charges at the bottom of the clouds repel the negative charges on the surface of the earth. This leaves the surface of the earth positive (the electrons on the ground migrate to get further away from the other electrons in the cloud). From there, the negative electrons from the cloud attract the positive electrons on the ground, which pulls electrons from the air. This usually occurs at a high point on the ground.Answer:When you have a thunderstorm that forms from convection and differences in temperature across a frontal boundary, you start to get differing charges building up between the cloud base and the ground. When the difference in charge gets great enough between the cloud base and the ground, the air becomes a conductor instead of being an insulator and a negatively charged stepped leader comes down from the cloud base and meets a positively charged return stroke from the ground. When this happens, we see visible lightning and positive charge is carried up into the cloud base, while negative charge is carried down into the ground, essentially it is a transfer of both of the charges involved in the electrical discharge. This lightning strike is called a negative strike because the stepped leader is negatively charged. There is also something called a positive lightning strike, where enough differing charge builds up between the top of the cumulonimbus cloud and the ground and the same transfer of positive and negative charges happens, but the stepped leader from the top of the cloud in this case is positively charged and the return stroke from the ground is negatively charged. Initially the top of the cloud is positively charged, the cloud base is negatively charged, and the ground is positively charged. Positive strikes are possible after several negative strikes between the cloud base and the ground have happened. Lastly, lightning strikes can go out a maximum of 10 miles ahead and behind the storm, so remember just the because it looks like the storm has passed, doesn't mean the threat of lightning doesn't exist.

Does lightning come from the clouds?
The source of lightning in thunderhead clouds is when there is a significant amount of ice in the cloud, most likely hail and there are 2 differing charges in 2 areas. The negative charge is at the bottom of the cloud, while the positive charge is at the top of the cloud. The ground is positively charge until there is an electrical discharge between the negatively charged cloud base and the positively charged ground, then it becomes mostly negative which then can open up the opportunity for a lightning bolt to jump from the top of the cloud, all the way down to the ground in another electrical discharge that is of greater electrical potential (voltage) than the first electrical discharge between the cloud base and the ground. This is because it takes more voltage to have a visible electrical discharge over a longer distance. There has to be 30,000 volts/cm of distance for a visible electrical discharge to occur.
